I try to use a F2-04RTD but the only reading I have is "0 "... I connect my "omega RTD-850 " (a PT100) to the F2-04RTD like this : RTD + ---- > CH1+ RTD - ---- > CH1- RTD Ground ---- > COM I try 3 RTD to be sure that is not a hardware problem. It seem pretty simple, but I don't know where is my mistake. The jummpers on the card is ok Ladder: I do what I found in the D2Analog PDF I use the slot 2 (the 3nd after the CPU slot) at the first scan LD K400 OUT V7662 LDA O2000 OUT V7672 and V2000-V2001 still at "0 " Thanks for your help

Time to break out the ohm meter and measure the RTD, you should be able to read 100 ohms. One set will read 0 ohms this will wire to (-) and the other to COM. The 100ohm lead then wires to (+).
