rainman Posted July 10, 2011 Report Posted July 10, 2011 Hi all, I have an old PLC codings as followed : FB 1 FW130 --------OPKT HLA --------- FW136 +3 -------- HL N LL A --------- FW138 -3 -------- LL N Where can I find info and operands about this FB1? Thanks. Rgds.
Groo Posted July 11, 2011 Report Posted July 11, 2011 You have made 2 posts with code inserted. I have no idea what you are talking about with each, what you have written makes no sense at all and is not really the code you would be looking at, therefore I cannot help. Maybe it would be better to putv a screen shot and not your 'shorthand' version. eg ther are no Load, Transfer, And, Or or anything instructions shown, are the things you showing a block call???? who knows.
rainman Posted July 14, 2011 Author Report Posted July 14, 2011 Sorry was very very new to S5 (sad to say I got to touch on a very old PLC). I had managed to find the function block and understand what the FB is trying to do. Thanks anyway. Is there a way to insert function block (graphical way) in Step5 or do I have to do in a "statement" manner?
Groo Posted July 14, 2011 Report Posted July 14, 2011 If I remember correctly FB's can only be programmed in STL with Step 5.
rainman Posted July 15, 2011 Author Report Posted July 15, 2011 Oh yeah, thanks. Going to put STEP5 aside and use PG2000, its a much user-friendly software.
