5.14.1. Interface module "PLmC_Interface"
The interface between a central IEC61131-3 user program on C3 powerPLmC and
a local IEC61131-3 user program on a Compax3 servo axis T30 or T40 is created
with the program module "PLmC_interface".
The " PLmC_Interface" module must be called up in each Compax3 T30
which is operated as a slave on a C3 powerPLmC.
With Compax3 T40 this is only necessary, if the slave axis is programmed
directly (not with operating mode: "Slave on C3 powerPLmC (Cam programming
on C3 powerPLmC)")
The call-up must take place cyclically!
The module can be found in the "C3_PLmC_interface.lib" library, which must be
integrated manually via the library manager, if required.
FB name PLmC_Interface
Interface module for the control of C3 powerPLmC
VAR_OUTPUT
O0
BOOL Status of the digital output O0 on the C3 powerPLmC side
O1
BOOL Status of the digital output O1 on the C3 powerPLmC side
O2
BOOL Status of the digital output O2 on the C3 powerPLmC side
O3
BOOL Status of the digital output O3 on the C3 powerPLmC side
LocalEnable
BOOL Enable for the local IEC61131-3 program
LocalEnable switches to FALSE for one cycle, if a
command for this axis is activated on the C3 powerPLmC.
This helps to avoid that the axis will receive different
commands at a time.

Note:
The execution of all local motion functions should be coupled with the
LocalEnable output.
Via the outputs O0...O3, the outputs set by C3 powerPLmC can be set out via the
physical outputs with the aid of C3_Output.
Please note that the last 16 lines of the recipe array (C3Array.ColXX_Row17 to
C3Array.ColXX_Row32) are reserved for the communucation with C3 powerPLmC.
