    Hi all,
    My Task: To control write to registers to my MSI430 safety PLC from Leuze Electronic using a HMI as a master.
    Protocol: Modbus TCP

    MSI430 (Modbus TCP - server/slave)

    Generic HMI (Modbus TCP - client/master)


    I'm reading Okay from the Register address 401101-40110
    But I'm not able to write to the MSI PLC to address 402101-402109

    Please see the attached images for gateway description for the device.

    Please advice/guide on how this could be done.

    I have tried using MBPoll and it says Illegal Data Address.
    Kind Regards
    NarkO

    Please find the below link for the manual
