    i am trying to read the status register from a wago 750-8202 with control fro pfc200 installed.
    in the wago manual for e-runtime this is modbus registers 64010 - 64013. i need to be able to tell if the plc has stopped from the remote scada system.
    thanks for any help.

    Did you read the manual for 8202?

    Zitat:
    9.5.3 PLC Status Register
    Register 0x1040 provides the status (state) that the controller is currently in.
    Possible values:
    1 = PLC running − PLC status is RUNNING.
    2 = PLC stopped − PLC status is STOPPED.

    Zitat:
    9.6 Diagnostics
    9.6.1 Diagnostics for the MODBUS Master
    The status of the PLC, or of the control system, can be queried by the MODBUS
    master by reading the WAGO-specific register 0x1040 – “PLC Status” using
    MODBUS services FC3 (Read Holding Registers) or FC4 (Read Input Registers).
    The WAGO-specific register 0x1040 – “PLC Status” is explained in the Section
    “PLC Status Registers”.

    Hi,

    hm... let me check, think this is possible but how is your SCADA connected by which fieldbus / modbus or is OPC UA an option too for your SCADA?
