GS20 Drive Read but not Writing with GS20A-CM-ENETIP Card
I have a GS23-55PO1 with a GS20A-CM-ENETIP comms card connected to a productivity 2000 PLC. I have set the parameters on the drive to communicate using the adapter card and can get a read success. The write function says 'No Parameters" when it is off and "slave device fa" when it is triggered on. I have used this same set up in another project and had no problems. This PLC runs several other motors but using Modbus comms. I have replaced the comms card and still no results. For reference i do have a polling offset from the read and the write command. Any advice would be appreciated, Thanks.
GSR & GSW use Modbus communication. You need to set the GS20A-CM-ENETIP to Modbus.
