The of the analog measurement system consists in making a weight value correspond to an electrical signal transmitted by sensors.
This adaptation is made on site when the product is set up. It is a mandatory step to validate the measurements.
NOTE: The calibration function, forced or not, is only accessible in the offline mode with the PLC in Run mode.
Any non-calibrated module is in a detected channel error state (that can be seen in the debug screen or on the module by the flashing of channel 0).
Confirm that the first calibration is complete:
-
Zero Load
-
Standard Load
-
Save
Otherwise, the information returned is not valid.
It is not possible to carry out a calibration if the PLC processor is fitted with a Flash-EPROM memory card (TSX MFP P 128K or TSX MFP P 224K or TSX MFP P 384K).
Calibration can be redone throughout the module's life. The electronics characteristics do not require regular recalibration. However, legal constraints or the application's mechanical characteristics may require calibration, particularly for commercial transactions.
NOTE: Calibration is independent of the configured filter, but acknowledges measurement and stability information parameters.
You can choose one of the following 3 calibration types:
-
normal calibration (Perform the calibration function with a standard load calibration that is greater than or equal to 70% of the maximum weight.)
-
graded calibration (if a normal calibration cannot performed under the conditions previously described)
-
forced calibration:
-
CPU -> Module: being able to restore adjustments made to a different module in the event of a maintenance concern or duplication
-
Module -> CPU: being able to make the processor parameters conform with the parameters of a calibrated module that is connected to a new slot
-
software calibration that requires the firmware version of the weighing module to be ≥ 2.1.
How to use TSXISPY101 calibration by program
Enhancement has been done to the TSXISPY101 module from version V2.2 (since CPU V2.6) to enable some advanced functions about the calibration by program. In particular the soft and forced calibration.
