Turbo PMAC Setup for Using ACC-72EX
All interactions between PMAC and ACC-72EX occur through M-variables. Most of the important
registers which are required are mapped in the suggested M-Variable definition files generated by ACC-
72EX Setup Assistant software. The generated files can be included in the header section of the project
files in PEWIN32PRO2.
Note
If multiple ACC-72EX cards are in the same UMAC rack, the M-
variable macro names will be identical for both files, despite the file
name difference based upon the ACC-72EX base address. Make sure
to add a prefix or suffix to the macro names both in the header file and
definition file in order to distinguish the proper macro names for
different ACC-72EXs. Note that no macro name should be longer
than 32 characters.
There are multiple steps in getting the COMX module working with the network/fieldbus. Some of these
steps are protocol-specific, and it is recommended to follow the requirements based upon each protocol
manual provided by Hilscher.
Initialization PLC
Recall that ACC-72EX requires a reset after each power up, power cycle, $$$ (reset), or $$$*** (factory
default reset). This can be achieved with a startup (or initialization) PLC. Example:
