Hi to all, finally connect succesfully Mach3 to Beckhoff PLC via Modbus TCP, I can read and write values via Modbus TCP in Test screen, but Mach3 not write the values for step and dir in PLC attached to PLC Modbus Variables. I like control the mill whit Mach3 send to PLC the Pulse and Dir to PLC via Modbus TCP and de PLC send the signal to stepper drives. It's totally necesary the use of brains? I frefeed not use brains just only Setup TCP Modbus screen.

I look in the forum the same config and not find any thing about this.

Thanks,

modbus in mach is far, far, far to slow for step/dir
