Communication with Mitsubishi FX1N with FX 5U series PLC on Melsoft or MC protocol

Bhadresh

Hi All,

Have anybody does communication with Mitsubishi FX1N with FX 5U Series PLC.

We want to upgrade FX1n series PLC which were communicating on Melsec protocol till now.

New series PLC support Melsoft or MC protocol only. Is there any way to communicate with this PLC ?

  • Hi,

    We have had a number of customers successfully connecting to a FX5U.

    In Citect:
    - Use the MELSECQ protocol
    - define the port using the TCP_BOARD, with special opt "-I10.10.10.1 -P1290 -T" for TCP or "-I10.10.10.1 -P1290 -U" for UDP
    (10.10.10.1 should be replaced with the IP address of your PLC and 1290 is the port used)

    PLC side
    - Create a SLMP Connection Module in the Ethernet Configuration , using connection method "SLMP", protocol "TCP" or "UDP" IP address and port to match the above
