Is there a way to understand the PLC program if the connection with the KTP is active?

I want to know when the connection to the HMI device falls to block certain transactions.

Thanks for your suggestions

Hello automatizzando

if I understand you want to know in the PLC if the HMI is presend or not.

That you can do with the Area Pointer "coordination" in the PLC connection in the HMI Project.

In the Help System there is an exlaination how it works
