**Hello everybody!**  
I am needing that when the connection state of the S7 node is offline (attachment 1) I want to send the values to -1 to some specific variables that I have created inside the node.  
This is because we need to log and visualize when the problem occurs in the PLC.  
I don't know how to call the variable that identifies the state of the S7 node.

Thank you very much!

Have you tried using a status node set to monitor the s7 node, this should give some output that may help you, if the s7 node is compliant with the status node. Or possibly a catch node may work.
