Yaskawa MP2300
Non-communication between the PLC & the HMI through Ethernet port.

I am trying to achieve Memobus or Modbus TCP/IP communication between Yaskawa MP2300 controller & the HMI through Ethernet port on 218IF-01 module. The engineering communication between the Yaskawa software tool MPE720 & the PLC is OK. Also, the communication via Memobus protocol between the HMI & the MP2300 on serial port is OK. But on Ethernet, they are not communicating. In the tool, the status of communication channel is shown to be IDLE. I have done all the settings according to the manual. If anyone has worked on this or has any ideas, Please guide as to what may be the problem.
