I have a 1762-IF2OF2 and I would like to connect a temperature transmitter giving 4-20mA. What determines whether it is 3277-16383 and 6241-31202 in the SCP. I get 3167 in by 4 mA

Whether or not it is set up as "Scaled for PID".

See page 14.

Ok. Maybe I am stupid

But I do not understand. I have a SCP with Indput I: 1.0
Min 6241
Max 31206
SC min 0
SC max 100
F8:0 ....

But it is not the right value I get up

This will not work. 6241...31206 is not a valid range for this module.

Referencing the manual the rdrast posted for you:

Make sure that the DIP switches are ON (default) for Current. (Page 8)

Go to the advanced I/O configuration for that module in RSLogix 500. There you should be able to select how each channel is scaled. (Page 14)

Raw/Proportional 0...32760
Scaled for PID 0...16380

All of this information is available in the AB manuals.
