Each UDC entry has a port number (1Ć4), a variable name or
register/bit number, and a minimum (Val @ -10V) and maximum (Val
@ +10V) value. Val @ -10V" specifies the value of the variable that
will be output as the minimum voltage, and Val @ +10V" specifies
the value of the variable that will be output as the maximum voltage.
This allows a small area of the signal range to be displayed over the
full range of the 8Ćbit digitalĆtoĆanalog converter. Values are
transferred to the analog output every scan if CCLK has been turned
on in a UDC task that is running, and every 5 milliseconds if CCLK is
off.
Each PMI entry has a port number (1Ć4), a parameter number and
description, and a minimum and maximum value. You can select the
parameter from a list of available parameters and set the Val @
-10V" and Val @ +10V" values in the same way as for a UDC
module. Only data that exists on the selected PMI Processor can be
output to one of its meter ports. Values are transferred to the analog
output after every current minor loop scan in the PMI Processor.
Use the following procedure to set up the meter ports for the UDC
modules and PMI Processors.
Step 1.
Enter S" for Set Up UDC/PMI from the Monitor menu
shown in figure 18.1.
Step 2. Enter the slot number of the UDC module. The screen will
display the current variable name (or register and bit
number) and the minimum and maximum values for each
port on the UDC module. It will also display the parameter
number and name and the minimum and maximum values
for each port on the PMI Processors associated with the
selected UDC module (A and B).
Step 3. Enter U" to select the UDC analog outputs, A" to select
the PMIĆA analog outputs, or B" to select the PMIĆB
analog outputs.
Step 4. Enter the port (1Ć4) you want to configure.
Step 5. If you entered U" (UDC) above, enter the task name (for
LOCAL variable), the variable name or register and bit
number of the variable you want to assign to the selected
UDC meter port.
If you selected A" (PMIĆA) or B" (PMIĆB), select the
parameter you want to assign to the port. Use the Up
Arrow and Down Arrow keys to scroll through the list of
available parameters displayed on the screen.
Step 6. Enter a minimum and maximum value for the selected
variable in the Val @ -10V" and Val @ +10V" fields,
respectively.
Step 7. When you are finished setting up the UDC and PMI meter
ports, press <ESC> to return to the Monitor menu.
