Sree Posted July 27, 2018 Report Share Posted July 27, 2018 Hi, I am trying to connect a 4 to 20mA two wire current transmitter to SM43JR20. I hooked up everything and the PLC is showing some value too. But I am not sure how to properly read the input from the current transmitter in the ladder logic. I tried using linearization with analog input as x data and current value to be displayed as Y data but the value displayed is varying when ever I change the values in the linearization block. I looked at the manual but it is not helping. I have one more issue, How will you use a constant with decimal point in visilogic eg: 4.5. All I see are integer operands Thanks in advance Sreerag Quote Link to comment Share on other sites More sharing options...
