3.22.2.7 Reset AR lockout
When the AR function is in lockout status, it means that new sequences cannot be initialized,
because AR is insensitive to initiation commands. it can be released from the lockout state if all
blocked signals disappear (such as 79AR_LockoutAR BI=0) in the following ways:
• The function is reset through by 79AR_ResetAR BI manually or locally control.
• If the setting 79AR_AutoRst=1, the lockout is automatically reset after the reclaim time.
