General Mach Discussion / Mach 3/4 and modbus PLC
« on: May 31, 2006, 05:59:17 PM »
Hello,
I'm trying to get a modbus connection between my PLC (DL205 w/ D2-250 CPU) and Mach4. I've got a cable made and it's tested good. I've got the PLC's port 2 setup for modbus. In the Mach modbus configuration I keep getting "timeout" responses from the PLC.
Art mentioned having to have a special program running on the PLC to setup modbus addresses for IO points. I need help, I'm so out of ideas... Thanks.
