The only reason to learn this language is to support legacy equipment in the field, the newest of which is hopefully 8.5 years old already (so just 20 more years or something before no machine is running IL, right guys? Richtig Jungs?).

If you or someone you know is generating new code in IL, stage an intervention (or at the very least an interview to replace the obstinate dinosaur making that objectively bad decision). If they ever bother to release another revision, they will remove IL entirely as an IEC 61131-3 language. Instruction list was depreciated in the last revision of IEC 61131-3 from Feb 2013, so for the last 8.5 years, it hasn't been a good idea to make new code using this dead language. This is Instruction List (STL is Siemens for Instruction List, which is confusingly close to how an English speaker would abbreviate Structured Text, so I wish Siemens people would stop using the Siemens-only TLAs on here, especially this one). Use the Help file and the Berger books, they are great resources. I know that's really dimple stuff but it is a good place to start. Similarly, if you want to write a word to a location then use Load(L) and on the next line transfer (T). If you just want to write to a particular but then you just use one. Imagine an AND or an OR gate (usually drawn with two inputs) but instead of drawing the gate we'll just represent the inputs with letters (an A or an O) and the output with =.

Logic gates are something to think about when first learning how to read it. Instead I used it as a way to introduce FBD and then STL. Later, I went on to teach a class on using the S7 PLC and hardly spent any time on ladder. I taught myself how to read STL on that project. When I first started the group in company I was working for wrote everything in ladder but on a job with several groups collaborating I encountered STL. Yes, this can be useful to determine interlocks and such, but writing fresh nowadays tends to be best. I’m also of the opinion that things can be better designed rather than copy pasting. It’s just not a good language for a lot of things. Some “rungs” were 40 lines… try keeping that train of thought in your head.
I know STL and worked with it for ten years on a daily basis and it was absolutely atrocious to troubleshoot boolean logic. And for those situations, you can now add an STL rung in the middle of an FC or FB to do that and program everything else in the best language for it. STL is really only good for a set of instructions that are either not present in other languages (ladder and FBD mostly) or can be recreated differently by use of arrays rather than memory blocks. Siemens dropped support for STL on half of their controllers.īefore this happened there was no SCL, now it comes as default with all processors.Īll code from the S7-300/400 went to STL before being compiled to machine code, this is no longer the case with the 12 family.
