Error and exception handling in python-snap7

[simonelisto]

Hello everyone,

I have searched everywhere for documentation and real examples regarding exception and error handling in python-snap7, but I haven't found anything.

In my Python application (a GUI for a Siemens PLC), I have a thread that reads and writes using a continuous polling loop.
Everything works fine, but I'd like to handle any exceptions thrown during reading/writing or connection (e.g., lost connection, failed read, etc.).

Any suggestions?
Thanks for your support.

Closing -- this is a general Python programming question about exception handling, not specific to python-snap7. Python's built-in try/except mechanism works with all snap7 exceptions. See the snap7.error module for the exception classes raised by the library.
