Calibration Function of an Analog Module
(Original Document)
About us
Introduction
This function is only accessible in online mode. It is used to recalibrate the channels of each analog input module of a project.
Calibration is used to correct the long-term module drift. It can also be used to optimize the precision of the measurement at ambient temperatures other than 25 degrees Celsius.
Procedure
Procedure for accessing the Calibration function:
Step
Action
1
Access the rack configuration screen.
2
Double-click the analog module to be calibrated.
3
Select the Calibration tab.
Result: the Calibration screen appears.
Illustration
The figure below shows an example of a calibration screen.
Description
The table below shows the different elements of the calibration screen and their functions.

Function
1
Tabs
The tab in the foreground indicates the current mode (in this instance: Calibration). Every mode can be selected using the respective tab. The available modes are:
  • Calibration which can be accessed only in online mode,
  • Debug which can be accessed only in online mode,
  • Configuration.
2
Module area
Specifies the abbreviated heading of the module.
In the same area there are 3 LEDs which indicate the status of the module in online mode:
  • RUN indicates the operating status of the module,
  • ERR indicates an internal fault in the module,
  • I/O indicates a fault from outside the module or an application fault.
3
Channel area
Is used:
  • By clicking on the reference number, to display the tabs:
    • Description which gives the characteristics of the device.
    • I/O Objects which is used to presymbolize the input/output objects.
    • Fault which shows the device faults (in online mode).
  • To select a channel,
  • To display the Symbol, name of the channel defined by the user (using the variable editor).
4
General parameters area
Specifies the MAST, FAST or AUXi task configured. This heading is frozen.
5
Display area
This zone at "channel" level displays the ERR information for each channel: all the measurements are invalid; filtering and alignment are inhibited.
NOTE: All unavailable LEDs and commands appear in gray.
Use
For TSX AEY 800/810/1600, TBX AES 400 and TBX AMS 620 modules, only channel 0 needs to be calibrated for all the module channels to be calibrated.
For the TSX AEY 1614 module, only channels 0 and 8 need to be calibrated for all the module channels to be calibrated.
For the TSX AEY 414 module, general channel calibration must be performed.
