Jogvan Simun Sevdal Posted January 25, 2019 Report Share Posted January 25, 2019 Hey I just sat down with a brand new SM70-J-RA22 and started programming. I am going to use my AN 2, In6 for reference as to know the position of my valve. 4-20mA. I set the hardware jumper to the correct position for current. And now I wanted to test to see if it works. I want to test with my I/U simulator-tester (MS4201) but I get no raw values into my plc only flickers between 2 and 3. When I try to simulate the 4mA input I only read 3,58ma and when I try to simulate 20mA I only get 5,38mA. When I use the wheel on my instrument to turn 4-20mA upp and down nothing happens until I turn it almost all the way down and there I can go up and down from 0-5,38mA and on my plc the values change up and down from 0-3 accordingly . What can be the problem? I measure 6,6k ohm between 0V and terminal 9(in6). J.S Quote Link to comment Share on other sites More sharing options...
