How to Make a Software Calibration with a TSX ISP Y101, V2.1
(Original Document)
About us
Introduction
Calibration can be carried out on a Control Expert station connected to the PLC with a TSX ISP Y101 module (firmware version 2.1) using the calibration screen.
NOTE: Software calibration cannot be used for regulated weighing applications.
Procedure
The following procedure applies only to TSX ISP Y101 weighing modules with firmware version 2.1.
This table describes the procedure for calibrating the analog measurement system:
Step
Action
Result
1
Switch the rack on.
The product is initialized, carries out self-tests and receives its configuration.
2
Access the calibration screen while the processor is in RUN mode and the terminal is in online mode::
  1. Click the module's slot.
  2. Select the Configuration tab:
    • Set the Maximum Range (MR) to a value higher than the sum of the sensors' weight ratings.
    • Set the Low Flow (LF) to a value equal to the average of the sensors' sensitivities.
    • If needed, set the Scale Division (e) to less than 1.
  3. Validate.
  4. Select the Calibration tab.

3
Check that the counter output is empty.

4
Press the Zero Load button.
The module reports an error condition and any measurement is invalid.
The status of the flag %Iwr.m.0.4.6 Calibration_in_progress changes.
The module acquires the standard load weight reference, processes and positions the report.
5
In the Standard Load field, enter the value PN.xx where PN corresponds to the sensors' weight ratings and xx is not 0.
If the command is disabled, an error message appears.
The status of the flag %Iwr.m.0.4.6 Calibration_in_progress changes.
The module calculates the theoretical calibration coefficients.
6
Click the Save button to recognize the parameters resulting from calibration.
The module and the processor recognize and save the parameters resulting from calibration.
During the write phase, the measurement keeps reporting a channel error until the writing is complete. Measurement restarts when writing is finished. The measurement is valid.
7
Select Configuration tab, reset (MR), (LF) and (e) to their initial configuration values and validate.
