Hi, I have OPLC V350-35-TA24 what includes onboard I/Os and configurable via wiring 2 Analog, 2 PT100/TC, and 1 HSC/ Shaft-encoder Input. So, first, i made changes in hardware project where analog input 2 and 3 were 0-10V, I connected them with potensiometer (i used voltage divider, so to analog input went 0,33-11,5 VDC, pot supply camed from same supply as OPLC +24VDC, pot signal went to analog input, pot ground went OPLC 0V). I also changed jumper setting, input 5 (analog input 3) - JP4 B, JP10 A, input 6 (analog input 2) - JP8 B, JP9 A. I made new project were was only linearization block: X1=0, X2=1000 (10V), Y1=0, Y2=16384, input MI0, output MI20. BUT in online test MI 0 was zero, I changed input voltage, but still, no numbers. Then I tested other analog input, same story !???? Today I changed analog input 2 (input 6) hardware configuration- 4-20 mA, jumper setting - JP8 B, JP9 B. Also, before inputs were PNP, now I changed them NPN source - JP12 A. 4-20 mA source I connected: plus into OPLC +V input and minus into analog input. In linearization block were: X1=0, X2=1000, Y1= 3277, Y2=16383, input MI 0, output MI100. BUT in online test MI0 were zero. What Im doing wrong?!! test 1903.vlp
