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.
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.
