Channel change completed flag
When changing a channel to perform the offset/gain setting, use Channel change completed flag (XB) as an interlock
condition to turn on and off 'Channel change request' (YB).
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.
To configure the offset/gain setting creating a program, use this flag.
For details, refer to the following.
