M221 and TM3TI4/G

[DzmitryKuzmin]

Hellow, everybody!

I am developing a program for reading from a sensor with an analog signal of 4_20 mA.
I am using the T221 controller with the TM3TI4 module
During testing, I discovered that when setting the 4_20 mA signal, the value in my program does not change.
The connection is correct, the inputs are also configured correctly, I checked several times, in the program I made a banal output of the value to the screen without anything, the value does not change.
Tell me what can be checked or what I might have missed.

If it was my program, I should have measured the current from the sensor with an external multimeter, in series with your input, to be sure you do have the signals you are expecting.

How often are you reading the value? Sure not just reading once?

Reading is done on a permanent basis, for confidence I brought out another variable from another analog input on the controller itself. Another 0-10V sensor is connected there and the data changes in real time depending on the sensor change.
