Hi Chris, thank you for the reply.
My problem is not the netty WARN messages. My problem is that the program gets stuck in the getConnection call when using the ODOT gateway to interface my S7-300 PLC. I'm not sure but maybe my problem is related to this issue: https://github.com/apache/plc4x/issues/1204 [Bug]: CachedPlcConnectionManager get stuck if the connection with the PLC has a temporary interruption Em sex., 12 de jul. de 2024 às 12:55, Christofer Dutz < [email protected]> escreveu: > Hi Luiz, > > just some time ago someone reported this and I just recently found the > root-cause of it. > https://github.com/apache/plc4x/issues/1593 > Right now, I would simply ignore this message … it shouldn’t influence the > functionality of the driver itself. > > Does it work in general? > > Chris > > > Von: Luiz doleron <[email protected]> > Datum: Freitag, 12.
