Dear Sir, in the S5 system they used CPU 95U,and only 2-no of 16 DI & 16 DO, the addressare 1.In Slot 0 : CPU integratedDI/DOaddress starts from 32.0 to 33.7 2.In Slot 1 : DI/DO address starts from 64.0 to 65.7 3.In Slot2 : DI/DO address starts from 72.0 to 73.7 the hardware part completed. According to your point if they used any High Speed Inputs, they might have used some Hardware else there are counter available in the integrated CPU , its address is PW36 & PW38. here i am attaching the S5 Program pls cross check and give me a solution.

Hello Yokesh Kumar S it sees to me that someone simply used an "empty" part of the PII (Process Image Inputs, i.e. which does NOT have a physical I/O card associated with it) asa "memory" word to store values (if memory serves me correct, the 95 U will only update the part of the PII which has a physical Input associated with it. I suggest you verify this with your95U). Can't tell why someone would (ab)use PII relaetd Input Words in this way, but it is essentially the same as usingFlagwordsor DB words. By the way, PB3/NW16 writes into IW100, PB4/NW16 writes into IW102 and PB9/NW6 writes into IW104. I hope this helps |
