How to handle disconnected PLC?

[ENA]

Hello
I'm doing a bit of a code that writes a string to PLC depending on the statuses read from the same PLC, Micrologix 1400.
I got the functionality that I wanted, but I have a problem, which occurs when AdvancedHMI looses connection to PLC, which I simulate by disconnecting the ethernet cable. The error message occurs, as seen in the attachment.

How can I handle this error, so that my application doesn't crash and resumes normal operation, after the PLC is reconnected?

Shortly after posting this topic, I found this thread:

Anyway, additional advice would be appreciated.

When accessing the driver via code, the rule is to always wrap your code in a Try-Catch block to properly handle any errors.
