Grettings,
I have been talking on and off with Greg about a SS Drop out issue, Greg suspects it may be a ground issue, BUT, The Issue dissappears when a Modbus Driven PLC is taken out of the equation. (althought it shares panel ground with the SS external power supply).
I was wondering, If anyone here is running a SS, + Modbus/PLC + Brains + a simple Macro pump can you see if your SS will just disappear from the Mach3?
My Set up: Through Serial Modbus I am talking to a standard DL06, the ladder in the PLC is not complex, it is just straight trough I/O plus an Analog Output for Spindle control, and an analog input that reports back true spindle speed from the Spindle Drive. The PLC has control over the digital inputs/outputs of the AC drives i.e. Servo enable, fault reset, spindle fault.
and it does basic I/O control of the spindle and the I/O of the ATC on the spindle. Mach going through basic Brains that transfer the information from and to the PLC from the screen set in mach. I only use the Macro pump to send Error messages, about faults.
I was hoping someone who is running a SS, plus a PLC and Brians can they see if they think there may be somekind of Software conflict inside mach3 that may be causing a Bug with the SS Plug in. The PLC and Brains are NOT complex just striaght through I/O, and not neccessarily alot of I/O eigther.
I, like Greg think it may be a ground loop issue, but I am trying to elimate other potential issues, so if someone here can look at their set up to see if they run into a Drop problem with the SS.
Thanks,
Scott
