We are converting a PLC 3 system to control logix. This is the second system we have done. The trouble we are have is this system has (4) 1771-ES. We can’t seem to get any Wright messages out to the Servo. We did see some number come back through are read block that only after we homed the system with the PLC 3 and switch the RIO to the control logix processor with out powering down the servo. The data we seemed to get was current position while I jogged the servo via the hard wired jog inputs. What can we look for in are read/wrights to get this module running with a control logix processor?
