Lock function
If the locking feature is enabled, the operation of a channel can be inhibited by writing a value in a
communication object.
The value written is of the KNX type “enable”; please beware that the meaning of this
value is “
activate lock
”, which is not to be confused either with “enable
locking function
” or with “enable
output”. The meaning of the value can be optionally inverted through a configuration parameter (an “enable
on” value can be interpreted as “lock off”).
A locked output ignores the switching commands that are received for the duration of the lock, thereby
maintaining the status it has upon lock entry. The status of the output can be set to a particular value both
when the lock is set and when it is released; it is also possible to determine whether the lock status should
be maintained or changed on recovery after a bus power-off.
