Mach4 General Discussion / Modbus and Sim
« on: August 10, 2016, 05:10:24 PM »
Does the Modbus I/O work when using the Sim as the motion controller?
Reason I am asking is I am having no joy with it.
I can open open the diagnostics for the Modbus and watch an output bit enable/disable but the PLC doesn't see it.
if I send an Input to Mach4 from the PLC, I get nothing in Mach at al, not even in the diagnosticsl.
I have connected to Mach3 and all works as expected so I know the PLC is ok and the very simple ladder is fine.
