PLC Offline >< Online

when the plc is offline the flow stops, instead I would like to write the number "-1" in the following nodes, how could I do this?

Thanks very much for your help.

Use a status node to monitor the status of them nodes
Its relatively straightforward.
Give it a go & come back if you get stuck.

Alternatively - or complementary to that - you could use a trigger node configured as a watchdog timer. That could send you a -1 if no message has been received for a specific amount of time.

@Steve-Mcl, @kuema, thank you very much for your help, I have successfully used both solutions, the node completes the status node.
