Post by chanmina on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
For a long time now, I have used VirtualBox on a Linux Mint host to run the Codesys IDE without any problems. Every day, I put it to good use, and it never fails. Wine is not something to be trifled with. Probably not worth the effort. For Linux PLC developers, Codesys Go might be a game-changer. Very excited to give it a try.

Your function block instance is not called, so the code is not executed to set the light on when the button is pressed.

Post by struccc on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hi, Might be a good idea first to try out the connection and the device with some handy software, like Modbus Poll. There you can see better, what's really going on... - Is it really connected? - What error code does it return? - Can it read from the register address? - Maybe try Input registers and Holding Registers - can make a difference - Sometimes register addresses are messed up: shifted +-1 (mixing of 2 standards) - Sometimes register addresses start with offset 30000, 40000 ... - Are you using the right protocol? - Is it RTU or TCP? Maybe ASCII? - Can even have a look at the data packets, etc... All this is easier to figure out first with some modbus utility... and then to set it up in CODESYS should not be an issue. P.

I have now and it works. I had the idea that it had something to do with codesyscontrol.cfg, but where can I find a description of all the things you can set in codesyscontrol.cfg and its syntax?
