Chapter 2 Safety
Safety
TankRadar REX equipment is often used in areas where flammable
materials are handled and where an explosive atmosphere may be
present. To protect both the plant and the personnel, precautions must
be taken to ensure that this atmosphere cannot be ignited. These areas
are called hazardous areas and equipment within these areas must be
explosion protected.
A number of different explosion protection techniques have been
developed over the years. Intrinsic safety and explosion proof (or flame
proof ) safety are two techniques.
2.1
Intrinsic Safety
Intrinsic safety, IS, is based on the principle of restricting electrical
energy available in hazardous-area circuits such that any sparks or hot
surfaces, that may occur as a result of electrical faults in components,
are unable to cause ignition. Intrinsic safety is the only technique
accepted for Zone 0 hazardous areas. It is also safe for personnel and
allows equipment to be maintained without the need for a gas-free
certificate.
The basic principles of intrinsic safety are:
Note!
•
All flammable materials are grouped according to the energy
needed to ignite them.
•
Equipment located in hazardous areas are classified according to
the maximum surface temperature that it can produce and this
must be safe with the flammable gases that may be present.
•
Hazardous areas are classified according to the probability that an
explosive atmosphere is present, and this dictates whether or not
a particular explosion protection technique may be used.
For trouble shooting and repair work of components in or in connection to
intrinsically safe equipment, strict observance of the following rules is
necessary:
- Disconnect the power supply to the Radar Tank Gauge.
- Use a certified battery operated instrument only.
- Use Rosemount TankRadar REX original spare parts only.
Replacement with non-original spare parts may jeopardize the intrinsic
safety.

Explosion Proof
Explosion proof enclosures can be used when an explosion can be
allowed inside the enclosure as long as it does not spread to the outside.
The enclosure must be strong enough to withstand the pressure and
must have narrow gaps to allow the pressure to escape without igniting
the atmosphere outside of the equipment.
Note!
2-2
Any substitution to non-recognized parts may impair safety. The
explosion-proof (flame-proof ) enclosure of the Gauge Head must not be
opened while the unit is powered.

FOUNDATION Fieldbus Technology and
Fieldbus Function Blocks
3.1
Overview
This section introduces fieldbus systems that are common to all fieldbus
devices.
3.2
Introduction
A fieldbus system is a distributed system composed of field devices and
control and monitoring equipment integrated into the physical
environment of a plant or factory. Fieldbus devices work together to
provide I/O and control for automated processes and operations. The
FOUNDATION fieldbus provides a framework for describing these systems
as a collection of physical devices interconnected by a fieldbus network.
One of the ways that the physical devices are used is to perform their
portion of the total system operation by implementing one or more
function blocks.
3.2.1
Function Blocks
Function blocks within the fieldbus device perform the various functions
required for process control. Because each system is different, the mix
and configuration of functions are different. Therefore, the FOUNDATION
fieldbus has designed a range of function blocks, each addressing a
different need.
Function blocks perform process control functions, such as analog input
(AI) and analog output (AO) functions as well as proportional-integralderivative (PID) functions. The standard function blocks provide a
common structure for defining function block inputs, outputs, control
parameters, events, alarms, and modes, and combining them into a
process that can be implemented within a single device or over the
fieldbus network. This simplifies the identification of characteristics that
are common to function blocks.
The FOUNDATION fieldbus has established the function blocks by defining
a small set of parameters used in all function blocks called universal
parameters. The FOUNDATION fieldbus has also defined a standard set of
function block classes such as: input, output, control, and calculation
blocks. Each of these classes also has a small set of parameters
established for it. They have also published definitions for transducer
blocks commonly used with standard function blocks. Examples include
temperature, pressure, level, and flow transducer blocks.

The FOUNDATION specifications and definitions allow vendors to add their
own parameters by importing and subclassing specified classes. This
approach permits extending function block definitions as new
requirements are discovered and as technology advances.
Figure 3-1 illustrates the internal structure of a function block. When
execution begins, input parameter values from other blocks are
snapped-in by the block. The input snap process ensures that these
values do not change during the block execution. New values received
for these parameters do not affect the snapped values and will not be
used by the function block during the current execution.

Figure 3-1. Function Block Internal Structure
Once the inputs are snapped, the algorithm operates on them,
generating outputs as it progresses. Algorithm executions are controlled
through the setting of contained parameters. Contained parameters are
internal to function blocks and do not appear as normal input and output
parameters. However, they may be accessed and modified remotely, as
specified by the function block.
Input events may affect the operation of the algorithm. An execution
control function regulates the receipt of input events and the generation
of output events during execution of the algorithm. Upon completion of
the algorithm, the data internal to the block is saved for use in the next
execution, and the output data is snapped, releasing it for use by other
function blocks.
A block is a tagged logical processing unit. The tag is the name of the
block. System management services locate a block by its tag. Thus the
service personnel need only know the tag of the block to access or
change the appropriate block parameters.
Function blocks are also capable of performing short-term data collection
and storage for reviewing their behavior.

Chapter 3 FOUNDATION Fieldbus Technology and
Device Descriptions
Device Descriptions are specified tool definitions that are associated with
the function blocks. Device descriptions provide for the definition and
description of the function blocks and their parameters.
To promote consistency of definition and understanding, descriptive
information, such as data type and length, is maintained in the device
description. Device Descriptions are written using an open language
called the Device Description Language (DDL). Parameter transfers
between function blocks can be easily verified because all parameters
are described using the same language. Once written, the device
description can be stored on an external medium, such as a CD-ROM or
diskette. Users can then read the device description from the external
medium. The use of an open language in the device description permits
interoperability of function blocks within devices from various vendors.
Additionally, human interface devices, such as operator consoles and
computers, do not have to be programmed specifically for each type of
device on the bus. Instead their displays and interactions with devices
are driven from the device descriptions.
Device descriptions may also include a set of processing routines called
methods. Methods provide a procedure for accessing and manipulating
parameters within a device.
3.3
Block Operation
In addition to function blocks, fieldbus devices contain two other block
types to support the function blocks. These are the resource block and
the transducer block. The resource block contains the hardware specific
characteristics associated with a device. Transducer blocks couple the
function blocks to local input/output functions.
3.3.1
Instrument-Specific Function Blocks
Resource Blocks
Resource blocks contain the hardware specific characteristics
associated with a device; they have no input or output parameters. The
algorithm within a resource block monitors and controls the general
operation of the physical device hardware. The execution of this
algorithm is dependent on the characteristics of the physical device, as
defined by the manufacturer. As a result of this activity, the algorithm
may cause the generation of events. There is only one resource block
defined for a device. For example, when the mode of a resource block is
“out of service,” it impacts all of the other blocks.
3-3
Reference Manual

Chapter 3 FOUNDATION Fieldbus Technology and
308017EN, Edition 1/Rev. B
October 2007
Transducer Blocks
Transducer blocks connect function blocks to local input/output
functions. They read sensor hardware and write to effector (actuator)
hardware. This permits the transducer block to execute as frequently as
necessary to obtain good data from sensors and ensure proper writes to
the actuator without burdening the function blocks that use the data. The
transducer block also isolates the function block from the vendor specific
characteristics of the physical I/O.
3.3.2
Alerts
When an alert occurs, execution control sends an event notification and
waits a specified period of time for an acknowledgment to be received.
This occurs even if the condition that caused the alert no longer exists. If
the acknowledgment is not received within the pre-specified time-out
period, the event notification is retransmitted. This assures that alert
messages are not lost.
Two types of alerts are defined for the block, events and alarms. Events
are used to report a status change when a block leaves a particular
state, such as when a parameter crosses a threshold. Alarms not only
report a status change when a block leaves a particular state, but also
report when it returns back to that state.

Link Active Scheduler (LAS)
All links have one and only one Link Active Scheduler (LAS). The LAS
operates as the bus arbiter for the link. The LAS does the following:
•
recognizes and adds new devices to the link.
•
removes non-responsive devices from the link.
•
distributes Data Link (DL) and Link Scheduling (LS) time on the
link. Data Link Time is a network-wide time periodically distributed
by the LAS to synchronize all device clocks on the bus. Link
Scheduling time is a link-specific time represented as an offset
from Data Link Time. It is used to indicate when the LAS on each
link begins and repeats its schedule. It is used by system management to synchronize function block execution with the data transfers scheduled by the LAS.
•
polls devices for process loop data at scheduled transmission
times.
•
distributes a priority-driven token to devices between scheduled
transmissions.
Any device on the link may become the LAS, as long as it is capable.
The devices that are capable of becoming the LAS are called link master
devices. All other devices are referred to as basic devices. When a
segment first starts up, or upon failure of the existing LAS, the link
master devices on the segment bid to become the LAS. The link master
that wins the bid begins operating as the LAS immediately upon
completion of the bidding process. Link masters that do not become the
LAS act as basic devices. However, the link masters can act as LAS
backups by monitoring the link for failure of the LAS and then bidding to
become the LAS when a LAS failure is detected.

Only one device can communicate at a time. Permission to communicate
on the bus is controlled by a centralized token passed between devices
by the LAS. Only the device with the token can communicate. The LAS
maintains a list of all devices that need access to the bus. This list is
called the “Live List.”
Two types of tokens are used by the LAS. A time-critical token, compel
data (CD), is sent by the LAS according to a schedule. A non-time critical
token, pass token (PT), is sent by the LAS to each device in ascending
numerical order according to address.
3.4.2
Device Addressing
Fieldbus uses addresses between 0 and 255. Addresses 0 through 15
are reserved for group addressing and for use by the data link layer. For
all Emerson Process Management, Rosemount Division fieldbus devices
addresses 20 through 35 are available to the device. If there are two or
more devices with the same address, the first device to start will use its
programmed address. Each of the other devices will be given one of four
temporary addresses between 248 and 251. If a temporary address is
not available, the device will be unavailable until a temporary address
becomes available.
3.4.3
Scheduled Transfers
Information is transferred between devices over the fieldbus using three
different types of reporting.
3-6
•
Publisher/Subscriber: This type of reporting is used to transfer
critical process loop data, such as the process variable. The data
producers (publishers) post the data in a buffer that is transmitted
to the subscriber (S), when the publisher receives the Compel
data. The buffer contains only one copy of the data. New data
completely overwrites previous data. Updates to published data
are transferred simultaneously to all subscribers in a single broadcast. Transfers of this type can be scheduled on a precisely periodic basis.
•
Report Distribution: This type of reporting is used to broadcast
and multicast event and trend reports. The destination address
may be predefined so that all reports are sent to the same
address, or it may be provided separately with each report. Transfers of this type are queued. They are delivered to the receivers in
the order transmitted, although there may be gaps due to corrupted transfers. These transfers are unscheduled and occur in
between scheduled transfers at a given priority.
•
Client/Server: This type of reporting is used for request/response
exchanges between pairs of devices. Like Report Distribution
reporting, the transfers are queued, unscheduled, and prioritized.
Queued means the messages are sent and received in the order
submitted for transmission, according to their priority, without overwriting previous messages. However, unlike Report Distribution,

Rosemount Tank Radar REX
Chapter 3 FOUNDATION Fieldbus Technology and
these transfers are flow controlled and employ a retransmission
procedure to recover from corrupted transfers.
Figure 3-3 diagrams the method of scheduled data transfer. Scheduled
data transfers are typically used for the regular cyclic transfer of process
loop data between devices on the fieldbus. Scheduled transfers use
publisher/subscriber type of reporting for data transfer. The Link Active
Scheduler maintains a list of transmit times for all publishers in all
devices that need to be cyclically transmitted. When it is time for a device
to publish data, the LAS issues a Compel Data (CD) message to the
device. Upon receipt of the CD, the device broadcasts or “publishes” the
data to all devices on the fieldbus. Any device that is configured to
receive the data is called a “subscriber.”

Unscheduled Transfers
Figure 3-4 diagrams an unscheduled transfer. Unscheduled transfers are
used for things like user-initiated changes, including set point changes,
mode changes, tuning changes, and upload/download. Unscheduled
transfers use either report distribution or client/server type of reporting
for transferring data.
All of the devices on the fieldbus are given a chance to send
unscheduled messages between transmissions of scheduled data. The
LAS grants permission to a device to use the fieldbus by issuing a pass
token (PT) message to the device. When the device receives the PT, it is
allowed to send messages until it has finished or until the “maximum
token hold time” has expired, whichever is the shorter time. The
message may be sent to a single destination or to multiple destinations.

Function Block Scheduling
Figure 3-5 shows an example of a link schedule. A single iteration of the
link-wide schedule is called the macrocycle. When the system is
configured and the function blocks are linked, a master link-wide
schedule is created for the LAS. Each device maintains its portion of the
link-wide schedule, known as the Function Block Schedule. The Function
Block Schedule indicates when the function blocks for the device are to
be executed. The scheduled execution time for each function block is
represented as an offset from the beginning of the macrocycle start time.

To support synchronization of schedules, periodically Link Scheduling
(LS) time is distributed. The beginning of the macrocycle represents a
common starting time for all Function Block schedules on a link and for
the LAS link-wide schedule. This permits function block executions and
their corresponding data transfers to be synchronized in time.

Grounding
Signal wiring of the fieldbus segment can not be grounded. Grounding
out one of the signal wires will shut down the entire fieldbus segment.
Shield Wire Ground
To protect the fieldbus segment from noise, grounding techniques for

It is highly recommended that you limit the number of periodic writes
to all static or non-volatile parameters such as HI_HI_LIM, LOW_CUT,
SP, TRACK_IN_D, OUT, IO_OPTS, BIAS, STATUS_OPTS, SP_HI_LIM,
and so on. Static parameter writes increment the static revision
counter, ST_REV, and are written to the device's non-volatile memory.
Fieldbus devices have a non-volatile memory write limit. If a static or
non-volatile parameter is configured to be written periodically, the
device can stop its normal operation after it reaches its limit or fail to
accept new values.
5.2
Overview
Each FOUNDATION fieldbus configuration tool or host device has a
different way of displaying and performing configurations. Some will use
Device Descriptions (DD) and DD Methods to make configuration and
displaying of data consistent across host platforms. Since there is no
requirement that a configuration tool or host support these features, this
section will describe how to reconfigure the device manually. Appendix H
Operation with Delta V shows the Delta V implementation of these
common functions.

about FOUNDATION fieldbus technology and the function blocks used in
the TankRadar REX 3900 Radar Gauge, refer to the FOUNDATION
fieldbus Block manual (Ref. no. 00809-0100-4783).
5.3
Assigning Device Tag and Node Address
The TankRadar REX 3900 is shipped with a blank tag and a temporary
address (unless specifically ordered with both) to allow a host to
automatically assign an address and a tag. If the tag or address need to
be changed, use the features of the configuration tool. The tools
basically do the following:
1
Change the address to a temporary address (248-251).
2
Change tag to new value.
3
Change address to new address.
When the device is at a temporary address, only the tag and address can
be changed or written to. The resource, transducer, and function blocks
are all disabled.
5.4
Configure Gauge
The wizard is used to do a standard configuration of the device. For
further information refer to the Rosemount TankMaster Winsetup User´s
Guide (Ref. no. 303027E) and Appendix C Register Transducer Block.
All settings that are made from this method can also be made manually
from the DD information, through the parameters listed below.

Configuration using the TRL/2 port
When using a TankRadar REX 3900 with FOUNDATION fieldbus the
configuration of the gauge is done via DeltaV or other Fieldbus Host.
With the help of Device descriptors these hosts are able to present, read,
and write necessary information and data within the gauge and assist the
user to a successful configuration of the gauge.
In some cases, there could be a need for a more advanced service
access to the gauge. This is done by using the TankMaster and
accessing the data from the TRL/2 Bus Port, which is always readily
available. Below are instructions of how to connect this port and how to
use it.
5.9.1
Electrical Connection
The Field Bus Modem is delivered, as standard, with a 3 m long cable for
the RS-232C connection to the PC. The TRL/2 bus connection is made
with a twisted pair of wires. The Field Bus Modem must not be used in a
hazardous zone as it is not explosion protected. The Field Bus Modem is
powered from an AC/DC converter (6-12 V, 150 mA) supplied by
Emerson Process Management / Rosemount Tank Gauging. In some
rare cases the Field Bus Modem can be powered from the RS-232C port
of the PC.

Operation and Maintenance
6.1
Overview
This section contains information on operation and maintenance
procedures.
Methods and Manual Operation
Each FOUNDATION fieldbus host or configuration tool has different ways
of displaying and performing operations. Some hosts will use Device
Descriptions (DD) and DD Methods to complete device configuration and
will display data consistently across platforms. The DD can be found on
www.fieldbus.org. There is no requirement that a host or configuration
tool support these features.
The information in this section will describe how to use methods in a
general fashion. In addition, if your host or configuration tool does not
support methods this section will cover manually configuring the
parameters involved with each method operation. For more detailed
information on the use of methods, see your host or configuration tool
manual.
6.2
Safety Messages
Procedures and instructions in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that raises potential safety issues is indicated by
a warning symbol ( ). Refer to the following safety messages before
performing an operation preceded by this symbol.

Service Method
This method is for service purpose only. If your host does not support
methods ENV_DEVICE_MODE it needs to be manually configured.The
following options are available:
6.2.3
•
FOUNDATION fieldbus:
Set the device in normal fieldbus communication mode.
•
Restart gauge:
Restarts the device, not the fieldbus card.
•
Set to factory default:
Sets all configured data to factory settings.
Calibration Distance Configuration
See “Configure Gauge” on page 6-1 for further information.
6.2.4
Master Reset Method (Resource Block)
To perform a master reset, run the Master Reset Method. If your system
does not support methods, manually configure the Resource Block
parameters listed below.
Set the RESTART = Run, Resource, Defaults, or Processor
6.2.5
•
Run = nominal state when not restarting (default)
•
Resource = not used by device
•
Defaults = sets parameters to FOUNDATION fieldbus default values
•
Processor = does a warm start of the fieldbus card and the gauge
Write Protection (Resource Block)
Inputs to the security and write lock functions include the hardware
security jumper, the hardware and software write lock bits of the
FEATURE_SEL parameter, the WRITE_LOCK parameter, and the
DEFINE_WRITE_LOCK parameter.
The WRITE_LOCK parameter limits access to modify parameters within
the block except to clear the WRITE_LOCK parameter. During this time,
the block will function normally updating inputs and outputs and
executing algorithms. When the WRITE_LOCK condition is cleared, a
WRITE_ALM alert is generated with a priority that corresponds to the
WRITE_PRI parameter.
The FEATURE_SEL parameter enables the user to select a hardware or
software write lock or no write lock capability. To enable the hardware
security function, enable the HW_SEL bit in the FEATURE_SEL
parameter. When this bit has been enabled the WRITE_LOCK
6-2
Reference Manual
308017EN, Edition 1/Rev. B

Rosemount Tank Radar REX
Chapter 6 Operation and Maintenance
parameter becomes read only and will reflect the state of the hardware
jumper. In order to enable the software write lock, the SW_SEL bit must
be set in the FEATURE_SEL parameter. Once this bit is set, the
WRITE_LOCK parameter may be set to LOCKED or NOT LOCKED.
Once the WRITE_LOCK parameter is set to LOCKED by either the
software or the hardware lock, all user requested writes as determined
by the DEFINE_WRITE_LOCK parameter shall be rejected.
The DEFINE_WRITE_LOCK parameter allows the user to configure
whether the write lock functions (both software and hardware) will control
writing to all blocks, or only to the resource and transducer blocks.
Internally updated data such as process variables and error logs will not
be restricted by the security jumper.
The following table displays all possible configurations of the
WRITE_LOCK parameter.

Simulation
For testing purposes, it is possible to manually drive the output of the
Analog Input Block to a desired value.
1
Note!
Power up the device. If the SIMULATE jumper is in the OFF position,
move it to the ON position. If the SIMULATE jumper is already in the ON
position, you must still remove the jumper and place it back in the ON
position.
As a safety measure, the jumper must be reset every time power is
interrupted to the device in order to enable SIMULATE. This prevents a
device that is tested on the bench using SIMULATE from getting installed
in the process with SIMULATE still active.
2
To change only the OUT_VALUE and not the OUT_STATUS of the AI
Block, place the TARGET MODE of the block to MANUAL. Then, change
the OUT_VALUE to the desired value.
3
To change both the OUT_VALUE and OUT_STATUS of the AI Block, set
the TARGET MODE to AUTO. Set SIMULATE_ENABLE_DISABLE to
ACTIVE. Enter the desired SIMULATE_VALUE to change the
OUT_VALUE and SIMULATE_STATUS_QUALITY to change the
OUT_STATUS.
If errors occur when performing the above steps, be sure that the
SIMULATE jumper has been reset after powering up the device.
6.2.7
Block Instantiation
The Rosemount TankRadar REX 3900 supports the use of Function
Block Instantiation. When a device supports block instantiation, the user
can define the number of blocks and block types to match specific
application needs. The number of blocks that can be instantiated is only
limited by the amount of memory within the device and the block types
that are supported by the device. Instantiation does not apply to standard
device blocks like the Resource, Level Transducer, and Register
Transducer Block. Block instantiation is done by the host control system
or configuration tool, but not all hosts are required to implement this
functionality. Please refer to your specific host or configuration tool
manual for more information.
Rosemount TankRadar devices are pre-instantiated with function blocks
at the factory, the default configuration for the Rosemount TankRadar
REX 3900 is listed below.

Diagnostics Device Errors
In addition to the BLOCK_ERR and XD_ERROR parameters, more
detailed information on the measurement status can be obtained via
DIAGN_DEV_ERR. Table B-7 on page B-7 lists the potential errors and
the possible corrective actions for the given values. The corrective
actions are in order of increasing system level compromises. The first
step should always be to reset the gauge and then if the error persists,
try to the steps in Table B-7. Start with the first corrective action and then
try the second.

Appendix C Register Transducer Block
Appendix C Register Transducer Block
Overview
The Register Transducer Block allows access to Database registers and
Input registers of the Rosemount TankRadar REX gauges. This makes it
possible to read a selected set of register directly by accessing the
memory location.
The Register Transducer Block is only available with advanced service.
Since this Register Transducer Block allows access to most registers
in the gauge, which includes the registers set by the Methods and
Configuration screens, in the Level Transducer Block (see Appendix A
Specifications) it should be handled with care and ONLY to be changed
by trained and certified service personnel, or as guided by Emerson
Process Management / Rosemount Tank Gauging support personnel.

Appendix E Analog-Input Block
Overview
The Analog Input (AI) function block processes field device
measurements and makes them available to other function blocks. The
output value from the AI block is in engineering units and contains a
status indicating the quality of the measurement. The measuring device
may have several measurements or derived values available in different
channels. Use the channel number to define the variable that the AI
block processes.
OUT_D

OUT
OUT=The block output value and status
OUT_D=Discrete output that signals a selected
alarm condition
Figure E-1. Analog-Input Block
The AI block supports alarming, signal scaling, signal filtering, signal
status calculation, mode control, and simulation. In Automatic mode, the
block’s output parameter (OUT) reflects the process variable (PV) value
and status. In Manual mode, OUT may be set manually. The Manual
mode is reflected on the output status. A discrete output (OUT_D) is
provided to indicate whether a selected alarm condition is active. Alarm
detection is based on the OUT value and user specified alarm limits.
Figure E-2 illustrates the internal components of the AI function block,
and Table E-1 lists the AI block parameters and their units of measure,
descriptions, and index numbers.

Simulation
To support testing, you can either change the mode of the block to
manual and adjust the output value, or you can enable simulation
through the configuration tool and manually enter a value for the
measurement value and its status. In both cases, you must first set the
ENABLE jumper on the field device.
Note!
All fieldbus instruments have a simulation jumper. As a safety measure,
the jumper has to be reset every time there is a power interruption. This
measure is to prevent devices that went through simulation in the staging
process from being installed with simulation enabled.
With simulation enabled, the actual measurement value has no impact
on the OUT value or the status.

Signal Conversion
You can set the signal conversion type with the Linearization Type
(L_TYPE) parameter. You can view the converted signal (in percent of
XD_SCALE) through the FIELD_VAL parameter.
× ( Channel Value – EU*@0% )FIELD_VAL = 100
------------------------------------------------------------------------------------( EU*@100% – EU*@0% )
* XD_SCALE values
You can choose from direct or indirect signal conversion with the
L_TYPE parameter.
Direct
Direct signal conversion allows the signal to pass through the accessed
channel input value (or the simulated value when simulation is enabled).
PV = Channel Value
Indirect
Indirect signal conversion converts the signal linearly to the accessed
channel input value (or the simulated value when simulation is enabled)
from its specified range (XD_SCALE) to the range and units of the PV
and OUT parameters (OUT_SCALE).
FIELD_VAL
PV = ⎛⎝ --------------------------------⎞⎠ × ( EU**@100% – EU**@0% ) + EU**@0%
100
** OUT_SCALE values
Indirect Square Root
Indirect Square Root signal conversion takes the square root of the value
computed with the indirect signal conversion and scales it to the range
and units of the PV and OUT parameters..
PV =
⎛ FIELD_VAL
--------------------------------⎞ × ( EU**@100% – EU**@0% ) + EU**@0%
⎝
⎠
100
** OUT_SCALE values
When the converted input value is below the limit specified by the
LOW_CUT parameter, and the Low Cutoff I/O option (IO_OPTS) is
enabled (True), a value of zero is used for the converted value (PV). This
option is useful to eliminate false readings when the differential pressure
measurement is close to zero, and it may also be useful with zero-based
measurement devices such as flowmeters.
Note!

Low Cutoff is the only I/O option supported by the AI block. You can set
the I/O option in Manual or Out of Service mode only.

Alarm Detection
A block alarm will be generated whenever the BLOCK_ERR has an error
bit set. The types of block error for the AI block are defined above.
Process Alarm detection is based on the OUT value. You can configure
the alarm limits of the following standard alarms:
•
High (HI_LIM)
•
High high (HI_HI_LIM)
•
Low (LO_LIM)
•
Low low (LO_LO_LIM)
In order to avoid alarm chattering when the variable is oscillating around
the alarm limit, an alarm hysteresis in percent of the PV span can be set
using the ALARM_HYS parameter. The priority of each alarm is set in
the following parameters:
•
HI_PRI
•
HI_HI_PRI
•
LO_PRI
•
LO_LO_PRI
Alarms are grouped into five levels of priority:
Priority
Number
Priority Description
0
The priority of an alarm condition changes to 0 after the condition that
caused the alarm is corrected.
1
An alarm condition with a priority of 1 is recognized by the system, but
is not reported to the operator.
2
An alarm condition with a priority of 2 is reported to the operator, but
does not require operator attention (such as diagnostics and system
alerts).
3-7
Alarm conditions of priority 3 to 7 are advisory alarms of increasing
priority.
8-15
Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.

Status Handling
Normally, the status of the PV reflects the status of the measurement
value, the operating condition of the I/O card, and any active alarm
condition. In Auto mode, OUT reflects the value and status quality of the
PV. In Man mode, the OUT status constant limit is set to indicate that the
value is a constant and the OUT status is Good.
The Uncertain - EU range violation status is always set, and the PV
status is set high- or low-limited if the sensor limits for conversion are
exceeded.
In the STATUS_OPTS parameter, you can select from the following
options to control the status handling:
BAD if Limited – sets the OUT status quality to Bad when the value is
higher or lower than the sensor limits.
Uncertain if Limited – sets the OUT status quality to Uncertain when
the value is higher or lower than the sensor limits.
Uncertain if in Manual mode – The status of the Output is set to
Uncertain when the mode is set to Manual.
Note!
The instrument must be in Manual or Out of Service mode to set the
status option.
The AI block only supports the BAD if Limited option. Unsupported
options are not grayed out; they appear on the screen in the same
manner as supported options.

Advanced Features
The AI function block provided with Fisher-Rosemount fieldbus devices
provides added capability through the addition of the following
parameters:
ALARM_TYPE – Allows one or more of the process alarm conditions
detected by the AI function block to be used in setting its OUT_D
parameter.
OUT_D – Discrete output of the AI function block based on the detection
of process alarm condition(s). This parameter may be linked to other
function blocks that require a discrete input based on the detected alarm
condition.
VAR_SCAN – Time period in seconds over which the variability index
(VAR_INDEX) is computed.
VAR_INDEX – Process variability index measured as the integral of
average absolute error between PV and its mean value over the previous
evaluation period. This index is calculated as a percent of OUT span and
is updated at the end of the time period defined by VAR_SCAN.

Configure the AI Block
A minimum of four parameters are required to configure the AI Block.
The parameters are described below with example configurations shown
at the end of this section.
CHANNEL
Select the channel that corresponds to the desired sensor measurement.
The Rosemount TankRadar REX 3900 measures Level (channel 1),
Distance (channel 2), Level Rate (channel 3), Signal Strength (channel
4), Volume (channel 5), and Average Temperature (channel 6).
L_TYPE
The L_TYPE parameter defines the relationship of the gauge
measurement (Level, Distance, Level Rate, Signal Strength, Volume,
and Average Temperature) to the desired output of the AI Block. The
relationship can be direct or indirect root.
Direct
Select direct when the desired output will be the same as the gauge
measurement (Level, Distance, Level Rate, Signal Strength, Volume,
and Average Temperature).
Indirect
Select indirect when the desired output is a calculated measurement
based on the gauge measurement (Level, Distance, Level Rate, Signal
Strength, Volume, and Average Temperature). The relationship between
the gauge measurement and the calculated measurement will be linear.
Indirect Square Root
Select indirect square root when the desired output is an inferred
measurement based on the gauge measurement and the relationship
between the sensor measurement and the inferred measurement is
square root (e.g. level).

XD_SCALE and OUT_SCALE
The XD_SCALE and OUT_SCALE each include three parameters: 0%,
100%, and, engineering units. Set these based on the L_TYPE:
L_TYPE is Direct
When the desired output is the measured variable, set the XD_SCALE to
represent the operating range of the process. Set OUT_SCALE to match
XD_SCALE.
L_TYPE is Indirect
When an inferred measurement is made based on the sensor
measurement, set the XD_SCALE to represent the operating range that
the sensor will see in the process. Determine the inferred measurement
values that correspond to the XD_SCALE 0 and 100% points and set
these for the OUT_SCALE.
L_TYPE is Indirect Square Root
When an inferred measurement is made based on the gauge
measurement and the relationship between the inferred measurement
and sensor measurement is square root, set the XD_SCALE to
represent the operating range that the sensor will see in the process.
Determine the inferred measurement values that correspond to the
XD_SCALE 0 and 100% points and set these for the OUT_SCALE.

can configure inversion and alarm detection on the input value.
The Discrete Input function block supports mode control, signal status
propagation and simulation.
Normally, the block is used in Automatic (Auto) mode so that the process
variable (PV_D) is copied to the output (OUT_D). You can change the
mode to Manual (MAN) to disconnect the field signal and substitute a
manually-entered value for OUT_D. In this case, PV_D continues to
show the value that will become OUT_D when the mode is changed to
Auto.
To support testing, you can enable simulation, which allows the
measurement value to be manually through the SIMULATE_D
parameter. Figure F-2 illustrates the internal components of th DI
function block, and Table F-1 lists the definitions of the system
parameters.

I/O Selection
To select the I/O associated with the discrete measurement, configure
the value of the CHANNEL attribute.
Simulation
To support testing, you can either change the mode of the block to
manual and adjust the output value, or you can enable simulation
through the configuration tool and manually enter a value for the
measurement value and its status. In both cases, you must first set the
ENABLE jumper on the field device.
Note!
All fieldbus instruments have an ENABLE jumper. As a safety measure,
the jumper has to be reset every time there is a power interruption. This
measure is to prevent devices that went through simulation in the staging
process from being installed with simulation enabled.
With simulation enabled, the actual measurement value has no impact
on the OUT_D value or the status.

Field Value Processing
You can configure the Invert I/O option (IO_OPTS) to process
FIELD_VAL_D. The invert option indicates whether or not the discrete
input is logically inverted before it is stored in the process variable
(PV_D).
The output of the Invert processor is PV_D. This value goes to the mode
switch where it becomes OUT_D when the mode is Auto. OUT_D is also
tested for an alarm state. You might choose this option when the field
contact is normally closed, so an open contact or a broken wire
represents the active state of the condition being sensed.
Note!
INVERT is the only I/O mode that the DI block supports. You can set the
I/O option in Manual or Out of Service mode only.
Alarm Detection
To select the state that initiates an input alarm, and to set discrete alarm
substatus in the output, configure the DISC_LIM attribute. You can enter
any value between 0 and 255. A value of 255 disables the alarm.
Block Errors
The following conditions are reported in the BLOCK_ERR attribute:
Simulate Active - Simulate_D is enabled and OUT_D does not reflect
actual process conditions
Input Failure/Process Variable has Bad Status - The hardware is bad,
the configured channel is invalid or a Bad status is being simulated
Out of Service - The block is not being processed
Modes
Manual (Man) - The output is disconnected from the field.
Automatic (Auto) - The block algorithm determines OUT_D
Out of Service - The block is not processed. The output status is set to
Bad: Out of Service. The BLOCK_ERR attribute shows Out of Service.

Status Handling
Under normal conditions, a Good: Non-cascade status is passed through
to OUT_D. The block also support Status Action on Failure and Block
Error indications.
Action on failure
In case of hardware failure, FIELD_VAL_D, PV_D and OUT_D change to
a Bad status and the BLOCK_ERR attribute displays Bad PV. When
SIMULATE_D is enabled, FIELD_VAL_D, PV_D and OUT_D change to
a simulation status. When the block is set to Man mode, OUT_D is set to
Good: Non-cascade, Constant status.
