Now, almost a 100% newbie on Factory IO here.
The way I understand it now is that one needs some PLC program to control any scene, unless you want to do it manually from the Factory IO UI. This is true regardless if you use an OPC UA Driver because OPC UA works on a publish/subscribe-like pattern, just listening/setting the tag values, not actually responsible for running a control program with Ladder or ST programs. Is that correct?
Since we currently do not have a physical PLC we aimed for running CODESYS. I downloaded it fine, entered the variables and code according to the Sorting scene example, but have not ever been able to connect to the local CODESYS Gateway or PLC running on my local machine, although they are proven to be running.
Any ideas? Any other easier to use preferable soft PLCs out there?
