Saving And Restoring Offset/Gain Values - Mitsubishi MELSEC-L Series User Manual

Saving and Restoring Offset/Gain Values

With the A/D converter module, you can save and restore offset/gain values in the user range setting.
In the event that the A/D converter module fails and need to be replaced, you can restore the offset/gain values of the
failed A/D converter module onto a replacement A/D converter module.
In addition, if multiple A/D converter modules are connected on a system, you can apply the offset/gain settings of one
of the modules to the other modules.
However, if you save and restore the offset/gain values, the accuracy after the restoration decreases by approximately
three times compared to that before the restoration.
Reconfigure the offset/gain as necessary.
