Dear Frinds.

Did you find the option to translate the program from CodeSYS to STL?

------------------------------------------------------------------------------------------
Split from Convert Codesys source code (IEC 61131-3) to Siemens Language (STEP7 or TIA Portal).

Hello Tincek;

One point to start with. Among the 5 PLC programming language standardized under IEC 61131-3, there are 2 that you seem to mix up: IL (instruction list) corresponds to Siemens' STL, whereas ST (structured text) corresponds to Siemens SCL.

Siemens STL resembles assembler programming, SCL is a high-level program close to PASCAL. It is already a lot of work within a Siemens program to translate from STL to SCL, so atranslator from a 3rdd-party programming language would be very difficult to generate. Codesys uses mostly ST, so what you should be looking for is to translate from Codesys to SCL.

I have located no sites offering a translator program between Codesys ST and Siemens SCL.

The Codesys organization website only recognizes the IOT2000 from Siemens, and none of their PLCs.

The best option you have is to learn both Codesys and SCL, and produce the ranslated code by hand.

Hope this helps,
