Installation on Actuator
Orientations, Normal and Reverse Acting
Normal acting is full CW when the process valve is closed and CCW when the process valve is open. Reverse acting
is full CW when the process valve is open and CCW when the process valve is closed.
90° indicator dome assemblies are design to accommodate any mounting arrangement and can be adjusted up to
9° off axis if needed. 45° indicator dome assemblies can only accommodate normal acting applications that are
mounted parallel ±9°. Consult your local distributor or factory representative for 45° reverse acting or mounted
perpendicular applications.
Illustration #1:
The image to the left shows a Valvetop unit mounted
parallel to the process valve in the closed position.
The green arrow at the top shows the “normal acting”
direction of travel to open the valve. This is the standard
orientation and your unit unless otherwise specified will
be factory set to operate in this fashion.
Illustration #2:
The image to the right shows a Valvetop mounted
perpendicular to the process valve in the closed
position. The green arrow at the top shows the
“normal acting” direction of travel to open the valve.
Notice that the indicator dome has been rotated 90°
compared to the unit above.

Mounting
TopWorx has numerous mounting bracket kits available to meet your specific application, whether rotary or linear.
Consult your local distributor or factory representative for ordering information. The illustration shows a direct Namur
mount on a quarter turn valve. Refer to your mounting kit documentation for specific mounting instructions.
Storage
Until conduit, conduit plugs, and any applicable spool valve port connections are properly installed, the ValveTop
unit will not support its IP/NEMA rating as the unit ships with temporary covers. Ensure that it is stored in a dry
environment with a relative humidity range between 10%-95% and a temperature ranging from -40ºF (-40ºC) to
160ºF (71ºC). Once properly installed, the temperature range listed on the nameplate will supersede this storage
temperature range.
Illustration #3: Mounting Assembly
Installation Notes
1. Use caution not to allow undue axial (thrust) load on the shaft.
2. Cycle the valve a couple of times prior to final tightening of the
mounting kit hardware. This allows the shaft to self-center in the
pinion slot, or coupler. Refer to the dimensions and materials
section of this document for appropriate tightening torque.
3. Always use sound mechanical practices when torquing down anyhardware or making pneumatic connections. Refer to the Integrated
Pneumatic Control Valves section for detailed information on
pneumatic connections.
4. This product comes shipped with conduit covers in the conduit
entries in an effort to protect the internal components from debris
during shipment and handling. It is the responsibility of the
receiving and/or installing personnel to provide
appropriate permanent sealing devices to prevent
the intrusion of debris, or moisture, when stored
outdoors or when installed.
It is the responsibility of the installer, or end user, to
install this product in accordance with the National
Electrical Code (NFPA 70) or any other national or
regional code defining proper practices.

Pneumatic Hookup Procedures
Prior to connecting the supply air to the spool valve, flush the system to remove any debris or contaminates. Galvanized pipe can easily flake and contaminate the system and therefore is not recommended. A 40 micron point of use
filter at every device is recommended.
4-Way Spool Valves
The TopWorx spool valve is a 5 port, 4-way valve driven by an internally mounted pilot. The spool valve supply port
and work ports are marked as follows:
Highly Recommended
TopWorx highly recommends Locktite 567 brand thread
sealant. Do not use a hard setting pipe compound. If Teflon
thread seal tape is used, start the wrap on the second
thread from the leading thread of the fitting. This will prevent tape shreds from contaminating the spool valve seals.
Breathers (AL-M31) should be installed in the exhaust
ports to keep debris from falling into the spool valve and
damaging the seals. This must be addressed prior to installation, or storage.
A flow control may be used in Port 3, but should NEVER
BE USED in Port 5. Any blockage or restriction may cause
an internal pressure build-up inside the enclosure and pose
a safety issue.

Calibration of Target / Feedback
Calibration of the FOUNDATION Fieldbus SCM-FF
Never perform calibration procedure unless area is known to be safe.
·
·
For Intrinsically Safe models, unit must be wired in accordance with Control Drawing S-K088A, or I.S.
components may be damaged.
For standard explosion-proof models: The OPEN and CLOSED limit switches encapsulated within the
SCM-FF may be calibrated using a DC power supply set between 9-32V, or calibrated once connected
to the Fieldbus network.
Step 1
Connect the power supply, or Fieldbus wires, to the FF terminals. The terminals are not polarity sensitive.
With power applied to the FF terminals, the valve may be manually stroked using the Calibration Switch on
the SCM-FF.
Step 2
Place calibration switch to the CLOSE position. Valve should move to CLOSE position. If it does not, consult
troubleshooting section of page 11.
Step 3
Disengage the bottom Cam from the splined hub and rotate the bottom Cam clockwise until the Red LED
lights. Release the Cam to re-engage the splined hub.
Step 4
Slide the calibration switch to the OPEN position. Valve should move to OPEN position. If it does not,
consult troubleshooting section on page 11.
Step 5
Disengage the top Cam from the splined hub and rotate the top Cam counter-clockwise until the Green
LED lights. Release the Cam to re-engage the splined hub.
Step 6
Cycle the valve CLOSED and OPEN a few times using the calibration switch to verify both limit switches are
maintaining their set points.
Step 7
Place calibration switch in the FF position. If using a power supply to calibrate, disconnect leads to the
supply, and connect the Fieldbus loop when ready to put into service.
Step 8
Manipulate the transducer parameters via the control system as necessary for desired mode of operation.
NOTE: If using a reverse acting actuator, re-calibrate switches using Steps 3-6, but rotate counter-clockwise
for close and clockwise for open. Reverse Action must be set in the Transducer Block (see “Transducer
Block Initialization, Single-Dual Action”).

Resetting Factory Defaults in SCM
There are five restart options available for the Resource Block Restart parameter in the TopWorx DXP/DXS-FF. The
fifth parameter is Reset with Factory Defaults and will be implemented by writing 0x05 to the RESTART parameter.
This restart is used to reset the device to factory default initial values.
After Conducting a Reset of Factory Defaults the Device Tag Information will be lost, all DI &
DO Functions Blocks will be assigned to Channel 0 and The Transducer Block will be placed
in Out Of Service.
Do not power down the device for 40 seconds after you execute a “Restart with Factory
Defaults.” Non-Volatile Random Access Memory (NVRAM) is being written and must
complete before device loses power. The device condition is unpredictable if an early
power cycle is executed.

Appendix A: FOUNDATION Fieldbus Technology
Blocks and the User Application
The Fieldbus Foundation has defined a standard for building user applications. The Foundation standard is built
around “Blocks.” Blocks are used to represent different types of functions that the device performs and provide a way
of grouping different parameters and functionality together in an easy to understand framework.
A Fieldbus Foundation device has a Resource Block, Transducer Block, and Function Blocks.
Once the hardware of the TopWorx Sensor-Communication Module (hereafter known as SCM-FF) is set up, fieldbus
communication is used to set the transducer parameters to get the functionality desired. The desired transducer functionality is associated with a function block. The host system is then used to link the function blocks together, and the
application is downloaded to all of the devices in the loop.
Resource Block
The Resource Block describes characteristics of the fieldbus device such as the device name, manufacturer, and serial number. There is only one resource block per device.
Transducer Blocks
Transducer Blocks are the connection of Function Blocks to the real world. Many of the settings unique to a Fieldbus
Device are defined in the transducer block parameters.
The Function Blocks are typically standard between devices, so that they may be linked together to form easily constructed, interoperable applications. The Channels of a transducer block can be attached to a function block for use in
the application.
Function Blocks
Function Blocks provide the control system behavior. The input and output parameters of Function Blocks can be
linked over the fieldbus. The execution of each Function Block is precisely scheduled. There can be many function
blocks in a single user application.
The SCM-FF provides 5 Discrete Input (DI) and 3 Discrete Output (DO) function blocks. Configuration of all these
blocks is NOT required for full device operation.

Transducer Block Initialization
There are several settings in the transducer block that should be set before
commissioning of the SCM-FF.
Through these parameters, a user can configure a wide range of diagnostics
and alarms. These include cycle timers, and counters, as well as temperature
monitoring. The alarm conditions can be configured through a transducer
channel in one DI Block.
Also, the user may configure the SCM-FF for use in Single or Dual pilot valves
for Direct or Reverse Acting applications, all through convenient Transducer
settings.
(a) Diagnostics & Alarming
There will be 5 limit parameters that must be set during calibration. These
parameters will vary with the type of valve the device is operating. The alarm
priorities must also be set, depending on the application.
By simply changing the settings in the transducer, all the diagnostic limits and
functional settings can be set by the end user.
1.
Cycle Times
Set the Cycle Time Open Limit (LIM_CYC_OPEN_TIME) and the
Cycle Time Close Limit (LIM_CYC_CLOSE_TIME) parameters to
the maximum amount of time in seconds the valve is allowed to
complete its stroke before an alarm condition is invoked. If the LEDs
are enabled, they will blink for local notification of the time limit
alarms. If the Cycle Time Open Limit is exceeded, the green LED
will flash. If the Cycle Time Close Limit is exceeded, the red LED will
flash. Pushing the Alarm Reset Pushbutton on the board will stop
the flashing.
The default setting for both the Cycle Time Open and Cycle Time
Closed Time Limit is 10 seconds.
2.
Cycle Count
Set the Cycle Count Limit (LIM_CYC_COUNT) parameter to the
maximum number of valve cycles allowed before a Cycle Count
Alarm condition is activated.
The default setting for the Cycle Count Limit is 50000 cycles.
3.
Temperature
The Temperature High Limit (HI_LIM_BOARD_TEMP) parameter
should be set to alarm when the temperature sensor reads above a
user specified value and the Temperature Low Limit
(LO_LIM_BOARD_TEMP) will be set to alarm when the temperature
sensor reads below a user specified value.
The default setting for the Temperature High Limit is 50°C. The
default setting for the Temperature Low Limit is -10°C.
(c) Calibration Switch Functionality
The SCM-FF is shipped in a mode where the calibration switch is
active. A 9 to 32 VDC power supply can be used to activate and
deactivate the device, to open and close the valve, and set the target.
In order to enable the calibration switch in a safe manner, three
conditions are required to be true simultaneously. These are:
1.
2.
3.
The CAL_SW_STATE parameter transitions to Enabled when all
three conditions have been met simultaneously. This parameter will
transition to the disabled state when the Transducer Block is placed
into service or the CAL_SW_ARM is set to disabled.
NOTE
When the transducer mode changes from OOS mode,
the valve will go to the FF position calculated at the time
regardless of the current position of the valve or the
Calibration switch.
Transducer Special Diagnostic Features
During installation, a special diagnostic parameter called
ACTIVE _BLOCK_ALMS can be used to alert the user of configuration errors specific to the device. This block is used to conveniently
identify some of the issues that may arise with installing the SCM-FF.
The values returned are explained below:
a.
b.
c.
d.
e.
(b) Functional Settings
1.
Single-Dual Action
The ACTION_ELEMENT parameter is used to determine what
direction the actuator goes when energized. The 2 settings of the
ACTION_ELEMENT parameter are Direct and Reverse Acting.
“Reverse Acting” is to be used when the energized state is to close
the valve.
The Default setting for Action Element is DIRECT Action.
2.
Channel 13
Channel 13 is a user configurable input channel. The user can
define the functionality of a DI block associated with Channel 13
by selecting the appropriate bits in the CHAN_13_MASK parameter.
One of several alarms can be used to trigger a DI including cycle
count, over stroke timer, temperature or any combination of these.
The unit is shipped with Channel 13 set up for over/under temperature indication.
CAL_SW_ARM parameter is TRUE/Armed. The
operator may consider this like a calibration switch
lock out parameter when disabled.
The calibration switch on the SCM-FF must be in
the FF position. This allows smooth transition to
the manual control condition.
Transducer block must be in the Out Of Service (OOS)
mode. This sets all of the connected output parameters to
a BAD status, allowing upstream controllers to recognize
the device is not controlled by the control scheme.
f.
g.
h.
i.
None Active - No active block alarms are active.
Invalid Mode - The computed actual mode for the block is
not supported the block’s actual mode will go to out of
service.
Mode Error - The mode calculator detected an error.
Both Contacts Closed - Both contacts are closed.
Conflicting Channels Assigned - Conflicting output
channels have been assigned. (See DO Block Section
for a description of the correct configuration of output
channels).
Open without Close - An ‘Open’ output channel has been
assigned without a ‘Close’ channel.
No Output Channels - No output channels have been
assigned.
Out Of Service - Transducer block is out of service.
Invalid Input - The target position is not valid for the
current device configuration. Check the target setting
to insure that it is in the correct position.
Stroke Valve Method
The method allows the user to simply invoke the method, receive
appropriate warnings of using an operating process and then allow
the user to repeatedly open/close the valve while viewing the actual
feedback from the valve on the screen. This method automatically
makes the necessary transducer block mode changes to enter the
method and automatically reinstate the previous transducer block
mode when the method exits. This prevents the user from unintentionally rendering the device unusable from the host control system.

Fieldbus Foundation Transducer Channel Architecture
The SCM-FF has one transducer block with 13 channels. The 5 DI and 3 DO function blocks will link to these transducer channels through the standard channel selection capability. (See Function Blocks)
The 13 Transducer Channels are listed below.
Transducer Channels
Notes on Channels
Channels 1 and 5
These are Multi-value DO blocks standard with Fieldbus Foundation. Channel
1 is intended for use with a single control signal, while
Channel 5 is to be used with a dual control signal.
Channels 2, 3 and 4
Channels 2, 3 and 4 use 0 = false and 1 = true for open, close, and stop. This
gives a more comfortable interface for users more familiar with ladder logic. In
the situation where Open and Close are both true (or false) at the same time,
the last input is rejected as invalid.
Readback signals are 0 = false and 1 = true for is-opened, is-closed or isstopped. Channels 2, 3 and 4 cannot be used simultaneously with channels 1
or 5.
Channels 4 and 5
Available with a Dual-Control Pneumatic valve.
Channels 6, 7 and 8
Echoes the Readback information from channels 1, 2 and 3.
Channel 9
Reflects the input from a dry contact type of input wired into the
Auxiliary input screw terminals and uses 0 = closed, 1 = opened
reflecting the contact condition.
Channels 10, 11 and 12
Reflects alarm conditions in the valve. When something needs to happen in
response to these error conditions, a DI should be used to publish the state of the
alarm condition. These channels use 0 = false (no alarm), 1 = true (alarm condition
exists). CTOA, CTCA, and CCA are transducer channels that allow alarms to be
scheduled into the system. These alarms are:
Cycle Time Open Alarm (CTOA – Channel 10)
Cycle Time Closed Alarm (CTCA – Channel 11)
Cycle Count Alarm (CCA – Channel 12)
Above inputs are used in preventative maintenance and indicate when a valve is
operating outside of acceptable times. These channels exist so that some action on
the loop can be scheduled in critical applications. Cycle times may increase with an
increase in valve stiction, and/or a loss of air pressure. The times and counts used
as alarm limits are user settable (see Appendix 2).
Regardless of whether these alarms are linked to function blocks, these FF
standard alarms are always reported to the alarm handling host when one of
these conditions exists and the corresponding priority is set to greater than 1.
Channel 13
Stimulates activity when a set of alarm conditions exist. This channel uses a
user-settable mask to allow any of five alarm conditions to cause the linkable DI
parameter to become true. Channel 13 is a masked OR function. It includes the
previous alarms, as well as a Temperature High (TMPH), and Temperature Low
(TMPL) alerts. For TMPH and TMPL, a sensor is used to sense the temperature of
the circuit board. The user can select which of these alerts on Channel 13 are to be
used by masking out the undesired ones.

Appendix D: Discrete Output (DO)
Discrete OUTPUT Blocks (DO Block)
There are 3 FOUNDATION Fieldbus standard DO blocks and 5 output channels.
The DO blocks take discrete control data and translate it to actuation in the field.
These blocks are used to open and close the valve. There are 4 different strategies provided to open and close a valve, depending on the system being used,
and whether a single or dual action pilot valve is being used.
Single Block Control Method, Single Action (Default)
Set the Channel Parameter of DO1 to 1(Open/Close Output), and DO2 and DO3
to 0 (No Connection). The valve is now controlled by the wiring going to the V1
terminals. By writing a 0 or a 1 to this DO block will now open and close the
valve.
Single Block Control Method, Dual Action
Set the Channel Parameter of DO1 to 5 (Open/Close/Stop Output), and DO2
and DO3 to 0. The valve is now controlled by the wiring going to the V1 terminals and V2 terminals. By writing a 0 or a 1 to this DO block will now open and
close the valve. Writing a 2 to the DO block will de-energize both the V1 and V2
terminals, stopping a valve using a block center type of pneumatic valve.
To use the READBACK_D values for the BACK CALCULATION OUTPUT
DISCRETE parameter of the DO block, the following two options must be selected:
1. In the Resource Block the “Output Readback” option should be selected.
2. In the DO Block under IO_OPTS, select the “Use PV for BKCAL_OUT” option.
Configuration Error Handling
In order to minimize configuration errors, several write checking features have
been added to the SCM-FF. Write checks to the CHANNEL parameter of the DO
blocks should prevent illegal configurations. These illegal configurations are:
1.
2.
3.
Dual Block Control Method, Single Action
Set the Channel Parameter of DO1 to 2 (Open), DO2 to 3 (Close), and DO3 to
0. Now by writing a 1 to DO1, the valve will Open. Changing this value back to
0, and writing a 1 to DO2 will cause the valve to close.
4.
Three Block Control Method, Dual Action
Set the Channel Parameter of DO1 to 2 (Open) , DO2 to 3 (Close), and DO3 to
4 (Stop). Now by writing a 1 to DO1, the valve will Open. Changing this value
back to 0, and writing a 1 to DO2 will cause the valve to close. Changing this
value back to 0, and writing a 1 to DO3 will cause the outputs to terminals V1
and V2 to turn off, stopping an actuator using a block center pneumatic valve.
5.
Note on Energize to Close
To energize to close (also called Reverse Acting), the ACTION_ELEMENT
parameter must be reset to Reverse Acting. See the Transducer section for
more details.
If the two-state Channel 1 Open-Close has been assigned, an attempt to
assign Channel 2 Open, Channel 3 Close or the Channel 5 Open/Close/
Stop channels will be rejected with a write check.
If the three-state Channel 5 Open-Close-Stop has been assigned, an
attempt to assign the Channel 2 Open, the Channel 3 Close or the Channel 1 Open/Close channels will be rejected with a write check.
If the channel you are trying to assign has already been assigned to another Function Block, the write will be rejected with a write check.
If the Open channel has been assigned and the Close channel has not,
an ‘Open without Close’ block alarm is generated by the block. NO OTHER LOCK-OUTS ARE IMPLEMENTED (no write-check). This
becomes an open only valve. Without the close signal, the last position
will be maintained.
If the Close channel has been assigned and the Open channel has not,
a ‘Conflicting Channels Assigned’ block alarm is generated by the block.
NO OTHER LOCK-OUTS ARE IMPLEMENTED (no write-check).
This becomes a close only valve.
Error handling for the configuration of channels has been modified as well. The
Transducer Block has a special BLOCK_ALARMS_ACTIVE parameter which may
be used to diagnose a configuration problem. The configuration errors are listed in
Table 2.

Appendix E: Discrete Input (DI) Block
Discrete INPUT Blocks (DI Block)
There are 5 Discrete Input Blocks available on the
SCM-FF. The DI block takes the manufacturer’s discrete
input data, selected by channel number, and makes it
available to other function blocks at its output. These DI
blocks become available to the user when linked to one
of the Transducer Channels available for inputs.
Table 1:
DI Channel Parameter Settings List
A host may retrieve internal information at any time and
alarms are reported as they occur. To make a light come
on or another valve close requires a DI to publish the
information on the bus.
Channels
The 5 DI Function Blocks in the device are associated to
the real world by setting the CHANNEL parameter to the
desired Transducer Channel. Illustration 11 shows the
relationship between Transducer channels and the DI
assigned channels. The output of the DI block (viewed in
the OUT_D parameter) is defined by the DI block’s
CHANNEL assignment. The valid settings for the CHANNEL parameters are listed in Table 7.
By resetting a DI CHANNEL parameter to a different
transducer channel number (0, 6-13, see Table 1) an
end user may customize the functionality of the SCM-FF
to fit a particular application requiring DI’s on temperature
limits and cycle counts instead of the defaults.
