    Default Check communication with plc

    Hi all,

    I am new on the forum. Sorry if my post is not on right place.
    How to check communication with PLC (S7 tcp driver), and show status as flag on zenon SCADA. Example, comm. Good = flag value 1; comm. Bad (Lost) = flag value 0.
    Is there an built in mechanism to detect comm. status?

    Best regards.
