Preface: I'm suddenly charged with maintaining our TI505 after the contractor we've used for 15 years decided we were too far away to continue supporting us. I'm planning to take the next Seimens TI505 Programming/Maintenance class, but that's not scheduled until June, and I need to know at least the basics of this thing now. I've been reading and learning a lot here on this great forum, and it's been a tremendous help. But perhaps people will forgive me if I ask some really basic questions.
Right now I'm just trying to learn to read the program, and it's starting to make sense. But there're some symbols that I don't understand, and don't see a them explained here on PLC.net, so I suppose they may be TI505 specific.
Anyway, can anyone tell me what the :0: symbol represents?
What are MIRW#, MOVW#, and LDC# functions?
Thanks for your help and patience.
