Automatic Data Transfers Between PTMPM and PLC
The PLC CPU controls the PTM Processor Module (PTMPM) by sending it several %Q bits and
%AQ words during each PLC sweep. These %Q bits and %AQ words represent commands such
as Enabled/Disabled, Power/Synchro Mode, Display Mode, and Gain values.
In return, the PTMPM provides information to the PLC CPU by sending it several %I bits and %AI
words each PLC sweep. The information sent by the PTMPM includes voltage, current, power,
and phase values, as well as discrete fault status.
Compatibility
The PTM is compatible with all Series 90-30 CPUs, and the PTMPM module may be mounted in
any type of baseplate (CPU, Expansion, Remote).
