I decided to implement a TCP-IP interface after more initial testing. For testing I really like the simplicity of PLC like signal control.

One question I have is the usage of a bool as PLCOutput (eg start drive). My test application would set this PLCOutput to true, but it should also be set to false again. Who would be responsible to set the PLCOutput to false and when?

Ok, I thought of that as well, but can you give any direction on how to do that? Documentation? Example?
