Hello,
I'm working at a CPU 313C (using TIA portal), and i would like to optimize my work memory usage, once i can't increase this memory. For that i would like to know what really goes to the work memory. I've been looking for it, but i've just found concepts of memory's kinds.
For exemple IEC timers like TON consume more work memory then if i use a SIMATIC timer like S_PULSE?
I read another post that says: "Elliminate any blocks including Library functions that are not being used. If you are not using STL then look to start converting some LAD to STL."
When he says "blocks including Library" what does he means? And the language influence in that?(i'm using FBD).
Thank you now.
