Hi,
I have raspberry PI with codesys on. Codesys is free demo version limited on 2hours. Anybody have solution to activate licence ?

Thanks for your answers.

Find the routine where it does:
Read time
Read Hardcoded 2 hours
Check <
If False Jump to Shutdown

I don't have a raspberry pi or anything like that, but a simple time check should be fairly easy to patch out

I do it with script: restart every 118 minutes. But I search other solution.

any progress on finding a medizine ?
LOL, restarting each 118 min ... how does that work out for your control outputs.....

All output are shutdown ... not nice.

Hi, any news on this issue?? Maybe someone has solved it??

Try 4DIAC open source RTE alternative https://www.eclipse.org/4diac/en_rte.php

Any news about this question?

any update on this topic ?
4diac looks nice, but was very confusing and difficult to understand even how to make a simple TON timer logic.
It's all related to EventTrigger based block processing.
You have to trigger for ex. each block each x ms to simulate some sort of PLC scan cycle.
logic gates are limited (for ex. AND OR functions only with 2 or 3 input, not able to add more to one block).
IO communication does not seem provided (for ex. Modbus IO scanning) Modbus is there, but as libmodbus which requires I think a lot of self programming, reinventing the IEC code wheels.
CodeSys is much more ready made but requires all kinds of soft licenses, while a hardware PLC just runs with all available functionality already build in.
