Hallo everybody
Im pretty new in here about 2 min he he, i would like to get som help setting up my PLC, i have worked with step 7 before but its 5-6 years ago.
I have a CPU313C with build in PT100 Input, i have a ETF-197 PT-100 sensor from OJ ELECTRONIC in denmark, it have a range from -40 to 125 C
I have connected the PT-100 to the input on the card, and set up the hardware so its schould be a RTD-2L PT100 input, then i go to the variable table to monitor the input, my AI range is from 3 to 12 so i monitor my IW11, i get hex W#16#7FFF and its not changing.
What i need the temp for is to start a pump at 65 C and stop it again by 50 C, could somebody also help me explaine how to make that program.
