What’s New with PMAC Plot 1.19
There are numerous new features implemented in PMAC Plot Release 1.19 Software.
• FFT Conversion for quick or detailed plot
• Saving gathered data in quick or detailed plot
• Simulation mode
• Different default plot color for ease of printing
Using these new features is intuitive but for users interested in knowing more about them, more
information is provided in the following.
Installation
Run the Setup.Exe application on Disk #1 of this distribution. This will place all required files in
the appropriate locations on your system.
The default location for PmacPlot is C:\Program Files\Delta Tau\PmacPlot.
We suggest you reboot your system at the end of the installation process.
Command Line Parameter
PmacPlot is a 32-bit application separate from PEWIN32. PmacPlot can be launched from a
PEWIN32 menu item. PmacPlot can be run by itself.
If PmacPlot is run alone, use the PMAC device number as a command line argument.
Example: Assume there are two PMACs in the system: the first PMAC is device 0, and the
second PMAC is device 1. To talk to the first PMAC, run PmacPlot as follows:
C:\Program Files\Delta Tau\PmacPlot\PmacPlot.exe 0
The method of communication is determined by the settings of Motion Applet. If you want to
switch from PC-bus communication to serial port communication, you need to change the settings
in Motion Applet and then launch PmacPlot.

QUICKPLOT
QuickPlot
The quick plotting dialog box makes data acquisition and presentation easy. It is not required to
know any PMAC memory locations to gather or how to plot some common motor parameters. A
few simple menus and buttons control the address mapping.
Main Quick Plot Screen
Plot Title
In this field, a title can be given to a plot. This title will appear above the plot.
Motors to Gather
Click this button to open a window to select what information will be collected and for which
motors. Commanded encoder values, actual encoder values, and servo command output can be
commanded for up to eight motors. The servo command output is DAC output for PMAC and
current quadrature for PMAC2. A check mark indicates to gather data for that item.
Specify the Gather Period (I19), which tells PMAC how often to collect data from the selected
items. The units for the gather period are in servo cycles. With PMAC in its default jumper
setting for the servo interrupt, 1 servo cycle is equivalent to 440 µsec. Thus, if the Gather Period
should be 1, data will be gathered every 440 µsec. If the entered Gather Period is zero or
negative, the PmacPlot will give a warning and prompt for a reasonable value.

PMAC Plot User Manual
The number of motors displayed in this window depends on the type of PMAC in the system. If
there is an 8-axis controller PMAC in the system, there will be eight motors shown in this
window.
Define Gather Buffer
After the motors to gather data for have been selected, click this button to set up the appropriate
PMAC I-Variables for data gathering.
Note:
Data cannot be gathered until this button is clicked.
Begin Gathering
When ready to start gathering data, click this button. The amount of elapsed time is displayed in
the Gather Time field.
End Gathering
When enough data has been gathered, click this button to stop data gathering. The Gather Time
field will stop changing. At this point, the data can be uploaded.
Upload Data
Once data has been gathered, click this button to upload the existing gathered data from PMAC’s
memory into the PC’s memory.
Possible Choices
Before plotting the data, specify what items to see on the plot. Highlight items in the Possible
choice field and move them to the Left Plot Axis or Right Plot Axis fields.
Note:
There must be at least one selected item to be plotted. Up to four items may be
plotted against each vertical plot axis.
The motors selected to gather data for determine which items can be selected to plot.

QuickPlot
PMAC Plot User Manual
Example:
If specifying to gather data for motor #1’s actual position only, only motor #1's actual position,
actual velocity (1st time derivative of position), actual acceleration (2nd derivative), or actual jerk
(3rd derivative) may be plotted. In this example, commanded position, velocity, etc. cannot be
plotted because data has only been gathered for motor #1’s actual position. To plot the following
error for motor #1, gather data on motor #1’s actual and commanded position since following
error is defined as the difference between the two.
Add to Left
This button adds the selected item from Possible Choices field to the left plot axis.
Note:
Up to four items can be added. This means that only four items can be plotted
against the left plot axis. A total of eight items can be plotted with four items per
vertical axis at a time.
Add to Right
This button adds the selected item from Possible Choices field to the right plot axis.
Note:
Up to four items can be added. This means that only four items can be plotted
against the right plot axis. A total of eight items can be plotted with four items
per vertical axis at a time.
Left Plot Axis
This field lists the items to be displayed on the left plot axis. There can be up to four items
plotted against the left plot axis.
Note:
Up to eight items, four items per vertical axis may be plotted at a time.
Right Plot Axis
This field lists the items to be displayed on the right plot axis. There can be up to four items
plotted against the right plot axis.
Note:
Up to eight items, four items per vertical axis may be plotted at a time.
Remove Item
This button removes the selected item from the plot axis.
Note::
There must be at least one item on the left plot.
Horizontal Axis
Use this list box to specify what item is to be plotted on the horizontal axis. In most cases, the
horizontal axis is Time. However, other items can be chosen as horizontal axis.
Example: Choose one motor’s commanded position as vertical axis and another motor’s
commanded position as horizontal axis.

PMAC Plot User Manual
DETAIL PLOT
Detail Plot
In contrast to quick plotting (which allows plotting position, velocity, acceleration, jerk, and
command output for one or more motors), detailed plotting gives much more control and
flexibility over how the plots look and what information they contain. By using detailed plotting,
plots can be generated that also contain I/O bits, various internal registers (such as status
registers, A/D registers from PMAC accessory boards, etc.), DPRAM registers, M-, P- and Qvariables, and virtually anything in PMAC’s memory. This powerful tool is recommended for
those who have some experience with quick plotting and are familiar with PMAC’s memory map.
Main Detailed Plot Screen
The basic steps needed to create a detailed plot are:
1. Specify the addresses for PMAC to gather (called sources). There are a total of 24 sources
that can be specified and gathered (these pertain to PMAC I-variables I21 through I44).
2. Specify how these sources are to be scaled and processed (i.e. whether a source is to be
differentiated (to obtain velocity, acceleration, etc.) or to be bit-masked and so on. These
processed sources are called items. There are a total of 24 items.
3. Specify which items (i.e. plot curves) are to be included on a plot (for example, items 1 and 2:
commanded and actual position for motor #1). On any given plot, there can be up to four
items (or curves) – two for the left vertical axis and two for the right vertical axis. There are
a total of 26 plots.
Detail Plot

PMAC Plot User Manual
4. Proceed to initiate data gathering on PMAC by using the DEFINE GATHER, GATHER and
END GATHER commands. Use these as on-line commands, or include both the GATHER and
END GATHER commands in the motion/PLC programs (i.e. CMD ”GATHER” and CMD
”END GATHER”).
5. Upload the gathered data into the Executive and plot the results.
Items to Gather
Use this window to specify what PMAC addresses are to be gathered. These addresses are
referred to as gather sources. There are a total of 24 sources. PMAC can be instructed to gather
all 24 at the same time.
Address to Gather Dialog Box
In this window, specify the Gather Period (I19), which tells PMAC how often to collect data from
the selected sources. The units for the gather period are in servo cycles. With PMAC in its
default jumper setting for the servo interrupt, 1 servo cycle is equivalent to 440 µsec. The
specified Gather Period must be greater than zero. There are 24 input fields (labeled as source #1
through #24). Type any valid PMAC address (X, Y, L, D, DP, or F -type addresses). A cross
mark placed by the corresponding source field indicates what source will be gathered.
Specify a Variable to Gather (>>)
Next to each address field is a button labeled with a >> mark. Clicking this button opens up a
small dialog box, used to specify an M-, P-, or Q- variable to gather. When the OK button is
clicked, the address of the variable selected is then copied into the corresponding source field.
This feature allows easy specification of gathering a PMAC variable without having to look up its
address in PMAC’s memory map.
Example: To gather M-variable 121, select the M-variable and enter 121 as the variable number.
Or click on -> to check which address the M121 points to.

Detail Plot
PMAC Plot User Manual
Specify a Variable to Gather Dialog Box
To save the sources specified to a file on a disk, click the Save to disk button. Conversely, a set
of sources may be loaded from a disk by clicking the Load from disk button. Upload the gather
sources from PMAC’s memory (I-variables I21 through I44) by clicking the Upload from
PMAC button. Lastly, clicking the Use defaults button will copy default addresses into all
source fields. Remember that when OK is clicked, the specified sources will be sent to PMAC
immediately (I-variables I19 through I44).
Scaling and Processing
Use this window to specify how to scale and process a source. These processed sources are
referred to as items. Many times it becomes necessary to scale the values gathered by PMAC.
Example: If gathering a position register for a motor, to obtain data in units of encoder counts,
take the raw gathered position value, and divide by: 32 * Ix08 (where x is the motor number).
The default value for Ix08 is 96, so divide the raw gathered value by 32 * 96 or 3072. Since the
PmacPlot will always multiply the scale factor specified, multiply by 0.0003256 (which is the
same thing).
Scaling and Processing Dialog Box
Select one of the 24 items (labeled A through X) by double clicking it with the mouse, or
highlighting it and clicking the Edit button. A second dialog box will appear:

Item Name
This field contains the name or title of the item, as it will appear in the legend of the plot.
Units
This field contains the units of the item, as it will appear in the legend of the plot.
Source
This list box allows you to choose the source you wish to use for this item. Your choices are
from Source 1 to Source 24. The previously specified address of the selected source is shown in
parenthesis. If the source is shown with an asterisk next to it, this indicates that the source has
not been selected to be gathered.
Scale Factor
This field contains the scale factor that will be used to multiply the raw data samples from the
specified source. When plotting position, velocity, acceleration or jerk in units of counts, this
scale factor will need to be set to:
The default value for Ix08 is 96. Therefore, this scale factor is equal to 1 / (32*96) or 0.000326.
If your selected source is something other than position, velocity, acceleration or jerk, the scale
factor will be different (usually 1).
Differentiate
Use this list box to specify whether or not the source samples are to be differentiated.
Differentiation is used commonly for deriving velocity (Once), acceleration (Twice), and jerk
(Three times). In most cases, this will be set to None.

Detail Plot
PMAC Plot User Manual
Bit masking
A source may be specified to be bit-masked with a value. Often this technique is used to plot the
values of certain bits in a number. Click the Use bit mask button to enter a value for the bit mask
(hexadecimal values must be preceded with a $).
Note:
The Source address for bit masking has to be 24 bit (X or Y). Also check the
Shift result to LSB checkbox to shift the bits of the masked result to the right.
The value in the source will be treated as an unsigned data. The mask cannot be
more than seven digits in hexadecimal value.
Combine above with a Second Source
Selecting this button opens a different dialog box where two scaled sources can be combined.
Commonly this is used for items like following error, where the difference of two sources
(command position and actual position) needs to be calculated and plotted.
Scaling and Processing for Two Items
The dialog box allows the implementation of a mathematical operation on any two gathered
sources. Commonly this is used for items like following error, where the difference of two
sources (command position and actual position) needs to be calculated and plotted.
Scaling and Processing Dialog Box for two Items
The items in this dialog box function the same as in the previously described dialog box. Two
sources and two scale factors must be specified.
Combining Operation
Use this operation to specify how the two sources will be combined. This operation is performed
after the individual sources are scaled.
Do not Combine with Primary Item
Clicking this button opens the previous dialog box where only one source is used instead of
combining two sources.

Horizontal Axis
Use this list box to specify what item is to be plotted on the horizontal axis. In most cases, Time
will be plotted. However, a plot may be generated where one item is plotted (on the horizontal
axis) versus another item (on either the left or right vertical axis).
Example: If data gathering a program that commands two motors to move in a circle, plotting
each motor versus time will result in sine wave plots. If one motor is plotted versus the other (by
specifying one of the motors to be on the horizontal axis), the plot will yield a circle. To have
advanced stability analysis, create a phase plane with following error as horizontal axis and its
derivative as vertical axis.
Left Vertical Axis
Use this list box to specify what items are to be plotted on the left vertical axis. Specify at least
one item (and may specify up to two items). If only one item is desired, select None for the
second list box.
Right Vertical Axis
Use this list box to specify what items are to be plotted on the right vertical axis. Up to two items
may be specified. If only one item is desired, select None for the second list box. If no items are
to be plotted, select None for both list boxes.

The FFT conversion works for PPL, but it cannot convert PPL data saved in frequency domain
back to time domain.
• If position, velocity, acceleration, jerk, following error or DAC/Current information were
plotted and then saved in time domain, the FFT operation will generate frequency domain
information.
• If position, velocity, acceleration, jerk, following error or DAC/Current information were
plotted and then converted using FFT, and saved them in time domain, the FFT operation will
not generate time domain information.
Save Plot Data into a Text File and Recreate the Plot from Microsoft
Excel
PmacPlot can now save the plot data into a tab-delimited text file, which can be loaded into
Microsoft Excel to recreate the plot for the report. To open the saved text file from Excel, select
File, then Open; select the text file name and be sure the Files of Type is Text Files (*.prn, *.txt,
*.csv), and click Open. Excel will launch the Text Import Wizard. At step 1 of the wizard, select
Delimited at Original Data Type. At step 2, select Tab as Delimiter. Then click Finish at step 3.
Note:
The data of the horizontal axis (usually it is Time) will appear at the first column.
The legends of the series will appear at the first row.
After the file is successfully loaded, use Excel to regenerate the plot from the data.
Save Plot Data into a Matlab File (M-file)
The PmacPlot can also save the data into M-file, which can run in Matlab. In other words, all the
data can be exported to Matlab for further mathematical analysis.
If the data is saved into an M-file and run it in Matlab, the following texts will display in the
Matlab Window:
*********************************************************
* This file is generated by Delta Tau Data System's PmacPlot Software
* If you have any problem about this file,
* Please contact Delta Tau at (818) 998-2095
* The following column vectors are created:
* x_v : TIME (SEC)(X-Axis)
* y_0 : Mtr 1 Act Vel (Left Axis)
* y_1 : Mtr 1 Act Pos (Right Axis)
* Use the above vectors to generate your plots
* Ex. Plot(x_v, y_0)
*********************************************************
The information displayed will show the variable names for those created vectors. Usually, the
data of the horizontal axis will be stored in the vector x_v, and the data of the vertical axis and
right vertical axis will be stored in the vectors y_x , where x is an index number.

FFT (Fast Fourier Transform)
This feature was added n version 1.19 and may be used to translate time domain data to frequency
domain data. The algorithm used in the conversion is called Danielson-Lanczos Transformation
and may be found from the book Numerical Recipe. This algorithm is based on the premise that
the number of data points is a power of 2 and zero padding is done to ensure the property.
Frequency Range
It is important to note that setting the gather period (I19) and servo period (I10) will affect the
frequency range of the FFT.
• If only the low frequency range data are relevant, increase the gather period. For instance, if
I10 is set to the default value (3713991) and gather period to 10 (I19=25), the resulting
frequency range is 0 to 45 Hz.
• If higher frequency range data are needed, decrease the gather period. For instance, if I10 is
set to the default value (3713991) and gather period to 10 (I19=5), the resulting frequency
range is 0 to 225 Hz.
In addition, a sufficient number of the data points are needed to ensure data integrity. When I19
is set high, make sure that data gathering is done for sufficient time so that the number of data
points are adequate to perform FFT. If not enough points are gathered for FFT, an error message
will appear.
Logarithmic Plot
Choose whether the FFT will be plotted in the Cartesian or the logarithmic scale. Using
logarithmic scale may help to identify the finer detail in certain cases.
PMAC Plot 1.19 has Simulated Mode operation capability, meaning it no longer requires a
PMAC to be run on Windows 95/98/NT. The previously saved gathered data may be loaded in
Qgd, Dgd or PPL formats and the gathered data may be processed and plotted.

USING SIMULATED MODE
The following steps will enable simulated mode:
1.
First, make sure the PMAC drivers are unloaded in the PC. Click the Unload button
from the MotionExe.exe applet in Windows NT. In Windows 95/98, unplugging PMAC
will ensure that no drivers for PMAC are loaded.
2.
Start the PMAC Plot 1.19. The following message will be displayed.
3.
Click Yes to start the simulation mode. Click No to end the program.
4.
Load the gathered data files or PPL files.
5.
Now it is ready to plot.
