I think this is one of those RTFM moments, but after a couple days searching I'm out of manual to read!
I'm trying to set up a very basic setup - I just want Mach3 to turn on a PLC output (for now). I'm connecting to the PLC through a USB-Serial cable.
I think I've got things set up OK - on the Test Modbus dialog I can write a "1" to the address of interest (decimal 8192 for output Y001 in this case) and have it turn on, on the PLC. Great! I can turn whichever outputs I want on.
But then I'm running into problems actually tweaking the output in Mach3. I understood that port 0 means Modbus, so if I have Cfg#0 pointing at the address of Y001 (which works in the Test Modbus dialog), with 8 registers set to Ouptut-Coils, then I should be able to set Mach3's outputs to Port 0, pins 0-7. However I can't get any of those outputs to work.
What step am I missing? I've attached my config screens to compensate for my confusing verbiage above.
Thanks!
