special input transducer for ex
I have a question about an excard do I have to use a different input transducer,
because I have an Inputsignal 4...20mA and I can see it in Control builder f but it is not processed in the AI_TR building block and i always see 0,0!
Can someone please help me

What kind of IO module are You using?
AI_TR transforms analog inputs converted by analog input module into variable format UINT (12-bit) into variable format REAL. In other words the input of this blok must be UINT between 0 and 4098 to get output between 0,0 and 20,0 mA.
If You set signal range to 4...20mA then for any input IN<820 AI_TR will set Output OUT equal to DVL (Default value low) and I guess it's 0,0 mA in Your case.
It's a bit of a leap guess, but maybe it will work.
