-------------------------------------
Hi,
nice to hear that maybe you have found your problem I would like just to give
you a suggestion.
As pointed out bu Julian a lot of bad things could happen talking with a PLC
and these are reported to the user with errors coming from the request code.
Here [Connection
Cache|https://plc4x.apache.org/users/tools/connection-cache.html] is a little
example, actually using the new Connected Pool driver, that could give you an
idea about the errors you have to catch in your code.
Maybe you already did, I can't actually see in the picture you posted.
As a test you can easily perform by yourself, try to unplug the cable form the
machine where your code is running, the code could handle the error and restart
reading as soon as the connection is back again.
Hope to have given some hints.
Regards,
Stefano
