In this video, you will learn what is scaling in PLC and how to scale the 4 to 20 mA current signal.

The changes in the process variable affect the electrical analog signal (4-20mA) and that happens inside the transducer.

Then the changes of the analog signal (4-20mA) are to be translated into digital values using the ADC "Analog to digital converter (0-27648). And that happens inside the Analog module.

Then this value; the digital value is transferred to the CPU.
