Offset/gain setting mode status flag
■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 the offset/gain setting is configured by reusing a program that is used in a temperature input module of MELSEC-Q
series, check that this signal is used as the interlock.
For the programs of a temperature input module of MELSEC-Q series, refer to the following.
