[quote user="rajasekhar"]A I0.0 A I0.1 =Q 1.0 Hi Rajasehhar, On the commands you have used above I hope I can explain you some things. [:)] The first command is the one that makes the RLO (RLO = A I0.0), after that in the RLO is the status from I0.0, with that RLO is the"A I0.1" taken together, which is given a new RLO from the RLO before with A I0.1. Then the first use of the RLO is made with "= Q1.0" where the RLO is set to the output. RLO = Result ofLOgic operation{or something like that} [:blush:] This is one bit from the status-register that is used, also are there in the statusregister for jump-instructions several bits reserved to get information on "Equal", "Greater then", "Zero", etc.for all kind of REAL and INT commands. All those register are in the next handbook to see: S7-300 Instruction List CPU 31xC, CPU 31x, IM 151-7 CPU, BM 147-1 CPU, BM 147-2 CPU See especially page 17 where the STATUSWORD is shown. [;)] |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
