Hello GAS2, You can use -/+ 20mA configuration because this module doesn't give you aunipolar 0to20mA measurement. I don't think it will cause you a problem if you configure your module for -/+ 20mA (make sure that measurement range module is on position C). You can still use FC105 for scaling this signal or any other scaling function you have since the representation of 0mA will give you 0 decimal value and the 20mA will give you 27648 decimal value. You can find more info. on this module in S7-400 module data manual (Page 289) and you can understand the representation of analog values in page 190 in the same manual. Best regards. H-H |
