About Process Trend
About Process Trend
Overview
Uniformance Process Trend is a desktop trending and analysis tool you can use to
retrieve and view data from an operating plant or plants. Process Trend is
tag-based—all information you retrieve and view is based on the tags you select and
how you customize them.
Process Trend is a multiple document interface (MDI) application, which allows you
to view up to eight trends and up to 10 analyses at one time. This enables you to
compare trends and analyses across a plant and, by attaching to a remote PHD server,
to compare analyses with different plant locations.
You can also view traces from more than one plant on the same plot so you can
compare performance between different operating locations. Process Trend trends
tags on different time windows. For example, you can have a time span of two hours
for all tags, however one tag can have a start time of 4:00 p.m. and an end time of
6:00 p.m. while another tag can have a start time of 8:00 p.m. and an end time of
10:00 p.m. This time flexibility enables you to gather data that represents the plant
operations over the same time duration, at different periods of the day.
Following is an example of a plot trending eight different tags:

Click OK.
The default settings are saved and will be applied to all plots you create in
Process Trend.
Notes:
•
When using the Raw Retrieval Attribute type, a data reduction method called Best
Fit may be applied. The application of Best Fit depends on the number of data
samples that exist within the requested time period. If the number of actual data
samples exceeds the maximum number of values allowed by Process Trend, then
the Best Fit reduction will be applied automatically. See the “Visual PHD
Developers Reference Guide” (PIM3001) for details about Best Fit.
•
When using any interval based Retrieval Attribute type (all retrieval types except
Raw), the Best Fit data reduction may also be applied. In this case, the Best Fit
data reduction will be applied when the requested retrieval interval yields more
data values than Process Trend has allowed. In this instance, the retrieval interval
will be re-calculated such that the number of samples returned will be less that the
allowable maximum. See the “Visual PHD Developers Reference Guide”
(PIM3001) for details about Best Fit.

retrieved would start at the current time less one
hour. So if it was 12:00 noon, the data retrieved
would start at 11:00 am.
Notes:
•
When using the Raw Retrieval Attribute type, a data reduction method called Best
Fit may be applied. The application of Best Fit depends on the number of data
samples that exist within the requested time period. If the number of actual data
samples exceeds the maximum number of values allowed by Process Trend, then
the Best Fit reduction will be applied automatically. See the “Visual PHD
Developers Reference Guide” (PIM3001) for details about Best Fit.
•
When using any interval based Retrieval Attribute type (all retrieval types except
Raw), the Best Fit data reduction may also be applied. In this case, the Best Fit
data reduction will be applied when the requested retrieval interval yields more
data values than Process Trend has allowed. In this instance, the retrieval interval
will be re-calculated such that the number of samples returned will be less that the
allowable maximum. See the “Visual PHD Developers Reference Guide”
(PIM3001) for details about Best Fit.

Zooming in Plot Areas
You can use the zoom button to magnify an area of the plot. The zoom feature is
available on only time-based plots, such as trends and SPC charts. You can use
different Process Trend features to focus on specific areas of the plot.
The following features enable you to focus on a specific area of information in the
plot:
•
zoom buttons
•
crosshairs
•
hairline cursor
Using the Zoom Feature
Zoom values >
100% will increase
the timespan, while
zoom values <
100% will decrease
the timespan.
The zoom feature works in combination with the time span settings. For example, if a

Using the Hairline Cursor
You can use the hairline cursor to view trend data for specific coordinates on a plot.
The hairline cursor differs from the crosshairs as it shows trend data, rather than x-y
coordinate values on the plot. When you place the hairline cursor on a plot, it shows
the actual values representing the intersection between the hairline and the trace lines.
You can use the hairline cursor to view data in a plot by:
•
Placing the cursor on a plot and viewing the values that appear at the bottom of the
plot window. You can lock the hairline cursor and use the arrow keys to move the
cursor in small increments. This enables you to view data in a controlled format
rather than manually moving the mouse to position the hairline.
•

•
The date and time the tag information was retrieved.
•
The tag value.
•
The confidence level of the data.
Use the data table when you want to view the exact value associated with a plot and
to quickly identify confidence levels and areas that require closer analysis. The

Setting and Viewing Time Characteristics
You can modify the time characteristics in trend plots to obtain a different view of
the plotted data. The time span begin and end times in a plot may vary between tags.
However, all tags on a plot must be assigned the same length of time span. For
example, all of your tags have a two hour range, but one tag data collection period
might begin at 2:00 p.m. and end at 4:00 p.m., while another tag data collection
period might begin at 10:00 a.m. and end at 12:00 p.m. Both of these settings are
valid.
Working with Time Lags
A time lag represents the time offset value from the current time. This is shown on
the time scroll bar as the distance between the scroll button and the right edge of the
scroll bar. Each tag can have a different time lag (also called a time offset value).
This time lag value allows the user to review historical data for each selected tag.
Changing Time Spans
The time span setting represents the length of time in the plot x-axis. You can click
the time span control on the Time Span toolbar and select a Process Trend default
time span for the x-axis, or you can create a custom time span using the Plot Tag
Definition window.

Overview
Process Trend provides four different analysis charts that you can use to analyze
process data. An analysis chart can be based on the active plot, or you can select
specific tags on which to generate an analysis charts.
You can create the following analysis charts:
Use this chart…
To report…
Statistical
General statistical information in a graphic format. This
chart shows information such as normal distribution,
mean, and standard deviation.
SPC
General statistical process control information in a graphic
format. This chart shows information such as x-bar, upper
and lower control limits, as well as out of control values.
Regression
Standard regression information in a graphic format. This
chart shows information such as x-y plot and the line of
regression.
Power Spectrum
Standard frequency analysis information in a graphic
format.
When you create an analysis chart from a trend plot, the first selected tag in the
legend is analyzed in the chart. If the analysis uses two tags, for example, a
regression analysis, the first two selected tags in the legend are analyzed.
Setting Analysis Chart Options
The display set up for each of the analysis charts is very similar between different
chart types. For example, you follow the same procedures to modify the text, lines,
fonts, and colors used in charts. When you change the settings for one analysis chart,
the settings do not change for each open chart. You have to set the display options for

Analysis Chart Algorithms
Following are the algorithms for analysis charts.
Statistical Charts
You can set the following parameters for Statistical charts:
•
LSL: Low Standard Limit. The Low Extreme value in PHD server configuration
information is used as the default value for LSL, but users can modify it later.
•
HSL: High Standard Limit. The High Extreme value in PHD server configuration
information is used as the default value for HSL, but users can modify it later.
•
#Bar: Number of bars in histogram. The default value for #Bar is 10, but users can
modify it later.
•
Unit: Y Axis unit. The default value for Unit is Counts, but users can select Counts
or Percent.
The Statistics Analysis is based on N samples of a PHD tag data:
V[1], V[2], ......, V[N].
where N is the number of data samples with good value.
106 • Uniformance Process Trend User Guide
Analyzing Plots
The following analysis results will be obtained if the history data is valid:
Min is the Minimum Value of the V[].
Max is the Maximum Value of the V[].
Histogram: The Histogram is calculated by:
W is the width of a bar in a histogram, and
W = (Max - Min) / #Bar.
Counts[] is the heights of bars in a histogram if Unit is selected as Counts, and
Counts[i] = is the number of sample for ((i-1)W ≤ V[j] < iW)
Where i = 1, 2, ..., #Bar, and j = 1, 2, ..., N.
If the Unit is selected as Percent, the heights of bars in the histogram is Percent[i],
and
Percent[i] = Counts[i] / N
Mean Value Mean:
N
å V [i ]
Mean = i =1
N
Standard Deviation Dev:
Dev =
å ( V [i ]− Mean)
N −1

Normal Distribution Curve: The Normal Distribution Curve, where area is equal to
the histogram, is calculated by:
Y (x) =
æ ( x − Mean) 2 ö
WN
÷
expçç −
2 Dev 2 ÷ø
Dev 2π
è
where x ranges from Mean - 3Dev to Mean + 3Dev.
Process Capability Cp:

Regression Analysis Charts
You can set the following parameters for Regression Analysis charts:
•
Shift: Time Shift. The default value for Shift is 0, but you can modify it later from
0 to the Time Span / 4.
The Regression Analysis is based on Nx samples of a PHD tag data

and Ny samples of another PHD tag data Vy[1], Vy[2], ......, Vy[Ny].
and their time stamp array Ty[1], Ty[2], ......, Ty[Ny],
where Nx and Ny are the numbers of data samples with good value.
First, a new array V’y[1], V’y[2], ......, V’y[Nx] is calculated, and V’y[i] is the
interpolation value of Vy[] at the point Tx[i] + Shift. Where i = 1, 2, ..., Nx.

Interfacing to Process Trend
Interfacing to Process Trend
Overview
You can develop a programmatic interface to Process Trend. Applications can invoke
Process Trend by:
•
Passing trend input information via a command line interface.
•
Interfacing with a previously activated Process Trend, passing trend input
information using DDE.
VB Setup for Using DDE to Pass Information to Process
Trend
This example
assumes that the VB
application has a
control named label1.
When a change event
occurs in label1, the
example code is
executed.
The following example shows the setup from a VB application when you are using
DDE to pass information to Process Trend:
Private Sub Label1_Change()
On Error GoTo error_label1
‘// if nothing in label, exit sub
If Label1.Caption = "" Then Exit Sub
‘// setup label DDE attributes to talk to process
trend
Label1.LinkTopic = "Process Trend for
PHD|tpdtrend"
Label1.LinkItem = "labelDDE"
Label1.LinkMode = 2
Label1.LinkPoke
Exit sub
error_label1:
If Err.Number = 282 Then ' no app running
ret = Shell("c:\Program Files\Honeywell TPI\Process
Trend\phdtrend.exe vbNormalFocus)
Resume
Else
Msgbox err.number & ": " & err.description
End If
End Sub
Uniformance Process Trend User Guide • 119
Interfacing to Process Trend
Note: In the previous code:
•
label1.linkitem - represents the process trend control used to accept the DDE input.
•
label1.linktopic - represents the running name of Process Trend followed by the
LinkTopic (as defined in Process Trend).
•
label1.caption - represents the execution string to be processed by Process Trend.
Calling Options
The calling options for executing the VB setup are:
•
Passing Filenames to Process Trend (used only when invoking Process Trend).
•
Passing Tagnames to Process Trend (applicable to initial invocation or interfacing
with running Process Trend - DDE interface).
•
Passing Actions to Process Trend (applicable to interfacing with running Process
Trend only) - available only via DDE interface.
Passing Filenames to Process Trend
This is used only when invoking Process Trend.
[filename] where filename = fully qualified path + filename of the file to display
[/p]
print trend, then exit Process Trend
Example: : c:\Program Files\Honeywell TPI\Process Trend\phdtrend.exe
c:\data\trend1.plt /p
Passing Tagnames to Process Trend
This is applicable to initial invocation or interfacing with running Process Trend –
DDE interface.
[/H hostname]
where hostname = PHD host name for all tags listed. If this option is not
passed in, then the default PHD host name (as defined by the system environment
variable PHD_HOST) will be used.
[/T taglist] [/S timelist] [/N filename] [/L] [/U]
where taglist is a list of tags to plot, separated by semi-colons.
where timelist is a list of end times and desired time span enclosed by a
single quote; the timelist makeup is:
/S ‘endTime1,SpanInSeconds1;endTime2,SpanTimeInSeconds2;….
endTimen,SpanTimeInSecondsn’; (where n = number of Tags in taglist)
120 • Uniformance Process Trend User Guide
Interfacing to Process Trend
endTime can be either a relative time (like Now, or Now-3200s, or Yesterday, etc.)
or an absolute time (like 4/28/98 14:00:00); the SpanInSeconds must be the number
of seconds in the span to display; for example: 1 hour = 3600, etc. When displayed, if
all of the SpanTimeInSeconds are not the same, the largest SpanTimeInSeconds
will be used for the span time when plotting the tags.
where filename is the name to call the plot that will be displayed. The
filename must be enclosed in single quotes.
where /L and /U allow the user to specify whether the added tags will be
locked or unlocked. Only 1 of /L or /U should be used.
Example when invoking new Process Trend:
…phdtrend.exe /H phd1 /T tag1;tag2 /S ‘now,3200;09/28/98 15:00:00,7200’ /N
‘T1Test’ /U
Example when interfacing with running Process Trend via DDE:
Set Label1.Caption = “/H phd1 /T tag1;tag2 /S ‘now,3200;09/28/98 15:00:00,7200’
/N ‘T1Test’”
Passing Actions to Process Trend
This is applicable to interfacing with running Process Trend only – available only via
DDE interface
[/C filename]
Close file identified by filename
Example: set label1.caption = “/C testfilename”
[/F filename]
Set focus to the file identified by filename
Example: set label1.caption = “/F testfilename”
Interfacing to Process Trend via GUS Schematics
You can invoke Process Trend through a GUS Schematic. The following is a sample
piece of code that will use the DDE link and pass information to Process Trend. This
sample code passes only an existing file name, although any of the described inputs
could be passed. The GUS schematic initiates the communication by a pressing a
command key.

Frequently Asked Questions
Frequently Asked Questions
Retrieval Requests
1.
When I am trending tags using RAW data retrieval, the shape of the curve
changes whenever I zoom in or out. In some cases, if a bad value is displayed on
the trend, the bad value gap seems to change as well, getting smaller when
zooming in and larger when zooming out. What causes this?
Answer: When requesting RAW data retrieval, the amount of data that will be
returned is unknown due to data compression techniques being applied to the
collected data. Process Trend has a maximum number of data samples per tag
that can be processed. If the number of data samples is greater than this
maximum number, then a data reduction called Best Fit is automatically applied.
This reduction will preserve the critical points of a curve, such as the high and
low values, as well as bad value indication. As users analyze specific areas on the
curve via zooming, a new data request is made; the Best Fit algorithm is applied
again, returning a higher resolution set of data. As users zoom in, the Best Fit
algorithm will be re-applied until the number of raw data samples is less than the
maximum number of allowable samples. See the “Visual PHD Developers
Reference Guide” (PIM3001) for details about Best Fit.
2.
What is the maximum number of samples that can be processed for each tag
being traced?
Answer: For linear curves, the maximum number of samples before the Best Fit
algorithm is invoked is 2000 data samples; for step curves, the maximum number
of samples is 1000.
3.
When I am retrieving averages on a 1 minute interval, if I increase the time span
to 30 days, the retrieval interval frequency displayed on the legend of the plot
changes to 1298 seconds. Why?
Answer: When interval based data is requested, if the interval value, when used
with the requested time span, results in more samples than allowed for Process
Trend, then the retrieval interval is automatically re-calculated to return an
allowable number of samples. This is performed automatically so that the user
does not have to change both the time span and the retrieval interval when
modifying the initial request. Since the user has requested a new time span, it is
assumed that the time span should be given higher priority than the retrieval
interval.
Uniformance Process Trend User Guide • 123
Frequently Asked Questions
Retrieval Times
4.
Can I have multiple time axis scales? That is, when I plot tag1 and tag2 on the
same plot, can each of the tags be plotted against a different time?
Answer: Absolutely. While the time span for each of the tags must be the same,
for example each tag’s time span must be 2 hours, the start and end times for
each tag can be different. These start and end times can be modified directly in
the Plot Tag Definition dialog screen, or via the time scrollbar on the toolbar.
Select the tag to affect and the adjust the times.
5.
Can I have the same tag plotted multiple times on one plot?
Answer: Yes; this is usually done specifically for looking at one tag against
multiple time spans.
Plot Operations
1.
Can I unlock only 1 tag on a plot?
Answer: No, the lock/unlock is for the entire plot. If multiple plots are being
displayed, each plot maintains its own lock/unlock status.
2.
How do I change the physical characteristics of a plot? I want to change the
background color of the trace area.
Answer: See the section “Setting Plot Characteristics” for details on changing
the plot characteristics.
3.
Can I manipulate the time scrollbar without using the mouse?
Answer: Yes; if the hairline cursor is not on display, the right and left arrows
will simulate the same action as clicking on the right or left arrows beside the
scrollbar. If the <Shift> or <Ctrl> and the right or left arrow buttons are pressed,
the result is the same as clicking in the time scrollbar. Additionally, if the up or
down arrows are pressed, then a new timespan is selected, based on the order of
selection in the toolbar timespan list control. The up arrow will increase the
timespan, while the down arrow will decrease the timespan.
124 • Uniformance Process Trend User Guide
Frequently Asked Questions
Plot Printing
1.
When I have multiple plots displayed, can I print more than one plot at a time, or
must I request multiple print requests, one per plot?
Answer: Printing is performed on an individual plot only. There is no way to
print multiple plots with a single request.
Hairline Cursor
1.
When I position the hairline cursor, all of the values and times in the legend
change, such that all of the times for all of the tags displayed in the legend are the
same. Is this correct?
Answer: Yes; the function of the hairline cursor is to show the time value
represented by the hairline cursor as well as the value of the intersection between
the hairline and each tag’s trace. If tags are being traced against a different time
window, then the time values displayed in the legend will represent the
individual times for each of the traces.
2.
How can I manipulate the Hairline Cursor for fine tuning?
Answer: When the hairline cursor is displayed, use the arrow buttons (right and
left) to move the hairline 1 second at a time; use the <Ctrl> and the right or left
arrow buttons to move by 1 minute increments.

Uniformance Process Trend User Guide • 131
Glossary
server process
1.
A process in charge of communicating with the user process and interacting with
Oracle to carry out requests of the associated user process.
For example, if a user queries some data that is not already in the database
buffers of the SGA, the associated server process reads the proper data blocks
from the data files into the SGA.
Oracle can be configured to vary the number of user processes per server process.
In a dedicated server configuration, a server process handles requests for a single
user process. A multi-threaded server configuration allows many user processes
to share a small number of server processes, thus minimizing the number of
server processes and maximizing the use of available system resources. On some
systems, the user and server processes are separate, while on others they are
combined into a single process. If a system uses the multi-threaded server, or if
the user and server processes run on different machines, the user and server
processes must be separate.
2.
In SQL*Net, an Oracle process that receives SQL statements from the client and
sends them to the Oracle database on the server machine. The server parses and
executes the SQL statements, and sends data and status values back to the client.
standard deviation threshold
The amount a value may deviate from its regression estimate without being
considered a gross error. The amount is equal to the standard deviation multiplied by
the tag configuration parameter Gr Error Sigma Limit.
Statistical Process Control (SPC)
Statistical Process Control (as in the SPC analysis chart available with the
Uniformance Desktop Process Trend).
tag
An entity that is being collected and historized. Equivalent to a parameter on the
source system (for example, FC100.PV).
PHD uses three types of tags:
•
Process Tags - data collected by PHD real-time interfaces (point.parameter)
•
Virtual Tags - calculations based on collected, manual input and other virtual tags
•
Manual Input Tags - data collected and input manually into PHD tags
