Connections enable on/off

[Fumale]

Good morning,
My system consists of four machines that can be switched on or off randomly.
Is there a method to enable and disable the four opcua connections that communicate with the four machines automatically or manually from the graphical interface, not from the editor?
Regards
Alessandro

why switching? if the system is offline, you will not get any data. Error "offline" will come.

Can you indicate how to get the indication on the HMI of the status of the connections you posted?
Regards.

it depends on the possible data. but you have to build a script that creates a tag or topic that is boolean type. if you get data it goes to "true" if not to "false"
