Hi there! I already had a similar topic, it was solved back then, but still i find most problems with analog scaling in other projects... unfortunatly. I have 3 pressure transmitters 4-20mA from -1 to 10 bar. I added file with pictures, i changed all amplifiers to: -99/1005 (since it will adapt automatically). With gain 1,38 and offset -375. Between 1 and 2 the set pressure must be 1,5 bar (120*1,25=150) and reset 1 bar (80) Between 2 and 3 the set pressure must be 5 bar (400) and reset 4 bar (320) I thought this was the right way, but it's still not working. Does anyone know how to solve this, since i VM mapped the comperators and receive them on the HMI. But it's saying 15,3 and -3,6 bar (which it's impossible, so not real values). Thank you in advance!! AttachmentDoc1.docx (341 Downloads) |

Maybe this FAQ help for better understanding ... How do you scale measured values in LOGO! Soft Comfort? |
