Hi there,
I just got a sample Mach3 program from Art and I have been testing with CUBLOC modules.
They work fine with the Modbus protocol.
I got it working under "Setup Modbus Control" but I am not sure where the inputs or outputs of the Modbus shows up.
It's running in the background though fine without errors with this minimal code in CUBLOC which set the CUBLOC to Modbus RTU Slave mode:
Const Device = CB280
Opencom 1,115200,3,80,80
Set Modbus 1,1,20
Do
_P(0)=1
Delay 1000
_P(0)=0
Delay 1000
Loop
