Brian, I continue to be amazed at how fast the MachX software continues to be advanced...
I remember all to well problems coordinating Modicon PLCs over Modbus with GM-Fanuc robots...( I was an engineer on a 50 machine molding and packing line)
For example, with all the I/O in the host its a trivial thing to have a Jog swtich move an axis unless a limit switch is hit. With Mach, the axis move and the limit switch will be in the Mach software and the Jog input will be in the PLC. Do this for four directions, add a switch for jog speed, and then a handwheel for fine jog control and you can have a real mess.
Here's hoping you come up with an elegant and simple solution to this problem.
