How to scale analog input for M221?
I have a TM221CE24R PLC with a TM3AI8 extension. I want to scale an extension's analog input signal . What function or how this could be done?
And another question would be how could I set for analog input channels: measurement type ( voltage, current (2 or 4 wire), resistor, etc), measurement range (0-10V, 0-20mA, 4-20mA, etc)?

You can static scale a Analog input directly via ESME Basic. You can see the needed fields in the attached screenshot.
Minimum is the lowest value of the sensor at 0V
Maximum is the highest value of the sensor at 10V

Hi you can add here a symbol name (IVALUE_1 as example) for the scaled value.
Or you can directly use the Hardware Address %IW1.0
In the example i use as scale 0...300 for a pressure probel 0..30Bar
In that case means the value 123 = 12,3 Bar.

@Bastian_Schmitz, thanks for replying!
Any idea how to scale an analog input signal? I didn't find a function similar to the one existing in Machine Expert.

@Bastian_Schmitz, I'm a little bit confused. I understood how scaling settings are being done. What I don't understand is how I assign the scaling result to a MW, MD or MF.
Let's say I have a temperature signal 4-20 mA. For 4mA I have 0 °C and for 20mA I have 65°C. These values, 0 and 65, where should be put? Where you wrote 4000 and 20000 for 4-20 mA? If, for example, I get 15mA, the scaling result is about 40°C. How do I get this result?

Hi @Bastian_Schmitz,
thanks for your quick replies.
Hi @jhonut,
please find in addition the following link to a 25min video.
Analog input configuration is shown at around 7 min

I thought that symbol is assigned to analog input signal. Now it's clear. Thank you very much for your help!

I attach an example that uses a user function based on the equation of a straight line ( Y = mX+b )
Using the simulator you can see the behavior
