-----------------------------------------------------------
I have similiar problem that occurs when I write a value (int, bool, ...) to
PLC with some delay after successfuly connected (connection is still active and
reading values works) . If the value is written immediately after the
connection was established, it usually works.
PLC: S7-1512SP, security: none, OPC UA mode <=1.03 and 1.04
I tried PLC4X version 0.9.0, 0.9.1, actual 0.10.0-SNAPSHOT; JDK11 and JDK17 -
the problem is still occurring (exceptions on write, while connection is still
active and reading values still works).
-----------------------
[nioEventLoopGroup-3-1] WARN io.netty.channel.DefaultChannelPipeline - An
exceptionCaught() event was fired, and it reached at the tail of the pipeline.
It usually means the last handler in the pipeline did not handle the exception.
