A
Offset/gain setting mode status flag
■Device number
The following shows the device number of this input signal.
■In the offset/gain setting mode
When registering the value, which has been adjusted with the offset/gain setting, use Offset/gain setting mode status flag (XA)
as an interlock condition to turn on and off 'User range write request' (YA).
When the offset/gain setting is configured from the offset/gain setting window of an engineering tool, the setting is performed
properly on the window. Therefore, a program is not required to perform the setting.
When a sequence program used for the MELSEC-Q series A/D converter module is utilized to configure the offset/gain
setting, check that this flag is used as an interlock.
For the sequence programs for the MELSEC-Q series A/D converter module, refer to the following.

Conditioning Function) User's Manual
■In the normal mode
In the user range setting restoration, use Offset/gain setting mode status flag (XA) as an interlock condition to turn on and off
'User range write request' (YA).
For user range setting restoration, refer to the following.
