Re: Codesys Control Raspberry Pi SL
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.

Re: Codesys Control Raspberry Pi SL
any progress on finding a medizine ?
LOL, restarting each 118 min ... how does that work out for your control outputs.....

Re: Codesys Control Raspberry Pi SL
All output are shutdown ... not nice.

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

Re: Codesys Control Raspberry Pi SL
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.
