I've got a Q68AD-G (Mitsubishi A/D card) and I'm trying to set up channel 6 as a 0-5V range.
I've changed the SWITCH SETTINGS so that CH6 says "0-5V", saved it and done a WRITE TO PLC (if that makes any difference), but when I inject a voltage via a FLUKE 754 process calibrator, the raw values (D32) seen on the PLC are 0v=0000, 5V=2000 ... 10V=4000. I was expecting 5V to be equal to 4000 raw.
My conclusion is that the PLC seems to think it's 0-10V range.
Do I need to make more changes in GX Developer to make 5V=4000 raw ?
Thanks
