Hello everybody
My plc is S7-200 CPU226+EM231 AI2×RTD,when connect to Pt100 all is OK,i.e. when the temperature is 30 ℃,the data AIW0 is about 300(I use the channel one).but when I change Pt100 to Pt10000,the dip switch setting to 11011001,according to the EM231 RTD manual,the data AIW0×0.1=temperature value ,but now the data AIW0×0.1≠temperature value ,why?
