Appendix
A
Typical Parameter Download Program
This appendix describes how to set up and download parameters to the TCM from the PLC CPU.
The parameters are stored in the PLC %R table and sent in a predefined group of 3 words to the
TCM each sweep. It takes then 65 sweeps to update all the parameter data in the TCM on startup.
The program to parse the configuration data and send it to a TCM can be set up as in the
following programming example.
In this example the TCM is configured at:
%I0001 (length 64)
%Q0001 (length 24)
%AI0001 (length 28)
%AQ0001 (Length 3)
The parameter values to be sent to the TCM are located in %R0001 to %R0130. There are 16
parameters per channel plus 2 diagnostic parameters. These 130 parameters are continuously sent
(2 at a time) to the TCM to make sure the TCM always has the latest values.
The Index into the register array is located in %R0200. It is initialized to 1 and incremented by 2
each PLC scan. When it reaches 131 it is set back to 1 to repeat the process.
The Group number for the TCM is located in %AQ0001. Dividing the Index number in % R0200
by 2 each PLC scan creates it. The Group number has a range of 0 to 64.
