Calibration Function for a Remote Analog TBX Module
(Original Document)
About us
Introduction
This function is only available in online mode. It is used to recalibrate the channels of each input analog TBX module of an application.
Calibration can be used to correct long-term module drifts. It can also optimize the precision of the measurement at an ambient temperature other than 25°C.
Procedure
Procedure for accessing the Calibration function:
Step
Action
1
Access the Fipio bus configuration screen.
2
Double-click on the analog TBX to calibrate.
3
Select the Calibration tab.
Result: the Calibration screen appears.
Illustration
The figure below shows an example of a calibration screen.

Tabs
The tab in the foreground indicates the mode in progress (Calibration in this example). 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).
  • By clicking on the Channel, to select the channel or group of channels (maximum 4) to debug. To the left of the symbol there is a copy of the CHx channel LED.
4
General parameters area
Specifies the MAST or FAST task configured. This heading is frozen.
5
Display area
During calibration, all measurements are invalid, filtering and alignments are inhibited.
NOTE: All unavailable LEDs and commands are grayed out.
List
Calibration procedures differ according to the type of TBX AES 400 and TBX AMS 620 module.
