Coming from IT industry I am constantly disappointed about missing functionality in Automation programming languages. No ternary operators? No enums? I mean c'mon that stuff was probably implmeneted in C language back in 80's.. ------------------------------------------------------------------------------------------ |

What are you missing that would save you soooo much time it is worth updating the current ISO standard(s) for PLC programming languages, syntax & what each instruction does? https://en.wikipedia.org/wiki/IEC_61131-3 and https://plcopen.org/ Bring it up to the ISO committee rather than venting in a single PLC vendor's forums. Granted, I might agree with you in some cases - like enums. However, I can live without enums because we have PLC Tag User Constants, block constants (OB/FB/FC), and we can manage ways to associate array bounds using constants. An old article at Plant Engineering's web site talks about PLC vs PC determinism: https://www.plantengineering.com/articles/plcs-vs-pcs-for-industrial-control/
