Hello Lifrasil, Helmut_13, and all expert, I'm trying to build my first program with CPU 224 xp. I using Sequence Control Relay (SCR) step by step output instructions as follow, Program sequence once started with output Q1 ON, a.) I1 input engage and hold, output Q1 and all others output OFF. b.) I1 input dis-engage, only output Q2 ON. c.) I1 input engage and hold, output Q2 and all others output OFF. d.) I1 input dis-engage, only output Q3 ON. e.) I1 input engage and hold, output Q3 and all others output OFF. f .) I1 input dis-engage, only output Q4 ON. g .) I1 input engage and hold, output Q4 and all others output OFF. h .) I1 input dis-engage, only output Q5 ON. i .) I1 input engage and hold, output Q5 and all others output OFF. j .) I1 input dis-engage, only output Q1 ON. All step cycle On / OFF input signal by I1. But when this program download to CPU and simulation it don't WORK. Please assist and advise me how to complete above program. I look forward to a favourable reply from you. Thank for all expert. Regards, Nelson.

Hello, Once in a step the program will not see the upflank of M0.0 (network 2) Copy/ paste that line in all the steps and it will work, see attached PDF. Regards, Marcjan AttachmentProjectsequence.pdf (194 Downloads) |
