Calibrate the ControlLogix Analog I/O Modules Chapter 11
Calibrating in Either Program or Run Mode
You must be online to calibrate your analog I/O modules by using
RSLogix 5000 software. When you are online, you can choose either Program
or Run mode as the state of your program during calibration.
We recommend that your module be in Program mode and not be actively
controlling a process when you calibrate it.
Calibrate Your Input
Modules Input calibration is a multi-step process that involves multiple services being
sent to the module. This section has four parts as shown in the table. Each
input module requires attention be paid to specific calibration ranges.
Calibrating the 1756-IF16 or 1756-IF8 Modules
The 1756-IF16 or 1756-IF8 modules are used in applications requiring voltage
or current. The modules offer four input ranges:
• -10…10V
• 0…5V
• 0…10V
• 0…20 mA
However, you can only calibrate these modules using a voltage signal.
IMPORTANT
The module freezes the state of each channel and does not
update the controller with new data until after the calibration
ends. This could be hazardous if active control were attempted
during calibration.

IMPORTANT
Regardless of what application range is selected prior to
calibration, all calibration uses a +/-10V range.
