Calibrate the Module Chapter 6
Calibrate Input Channels
Input calibration requires that you apply reference signals to the module’s input
channels and then verify the channel status. ControlLogix high-speed analog I/O
modules can operate in Current or Voltage mode. For voltage applications, you
need to calibrate only the -10…10V range. Calibrating to this range calibrates the
module for all other voltage ranges, such as 0…5V.
Regardless of mode, when calibrating the module’s inputs, you must do the
following:
• Apply a low signal to a channel (or group of channels)
• Verify the channel’s low signal reference
• Apply a high signal to a channel
• Verify the channel’s high signal reference
The following example shows calibration of a single input channel. We suggest
you calibrate all channels each time you calibrate the module.
To calibrate the high-speed analog module’s inputs, follow these steps.
1. Connect your voltage calibrator to the module.
2. Access the module’s properties page.
Choose Properties.
Right-click I/O Configuration
