Christofer Dutz commented on PLC4X-314:
---------------------------------------
Hi,
having a look at the wireshark recording doesn't make me think there is
anything super special happening.
However the exception you are getting makes me think that perhaps the remote
plc is haning up. This can be for multiple reasons. Some hang up if the time
needed for handling IO exceeds a configured percentage of the cycle time.
Are you using our connection pool? This should automatically handle disconnects
transparrently.
