Chapter 7 Calibrate the Module
Controller State During Calibration
You must add the module to your Logix Designer application project, as
described in Chapter 6,
Configure the Module on page 83, before you can
calibrate it.
The project must be online with the owner-controller to calibrate 5069 Compact
I/O analog
I/O modules. You can calibrate in the following conditions:
• The controller in Program mode--either Remote Program or Program
mode.
We recommend that your module be in Program mode and not be actively
controlling a process when you calibrate it.
• If there are no connections to the module.
Calibration Impacts Data Quality on Entire Input Module Group
When a channel on a 5069 Compact I/O analog input module is being
calibrated, the Notch Filter setting for that channel changes to 5 Hz. This results
in the I.Chxx.Uncertain tag being set to 1 for that channel until calibration is
completed.
Grouped inputs share an Analog-to-Digital converter. As a result when any input
channel is in the calibration process, the I.Chxx.Uncertain tag is set to 1 for the
other input channels in that group. This setting is due to the fact that the data
sampling rate slows for all input channels in the group.
