    Is this a new installation or has it being running and now has this fault?

    The DeviceNet needs to be connected to 24 VDC - pin 1 = 0 V and pin 5 = 24 V.

    COMM LED is indicating not communicating on the network - have you setup the board in the EIO config file?

  • You need to have 24V power first on device net network pin 1 & 5. Also It is recommended to provide as much information as possible to get an better reply.
