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 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.
