Central function
The Gateway provides the option to link selected individual or all groups with a 1-bit central
communication object. The behaviour when activating a group via the central function is comparable to
a central group address linked with all "Switching" objects.
The groups assigned to the central function are activated according to the received central object
value. The polarity of the central telegram can be inverted via parameter.
The behaviour of the groups is identical to the 'normal' activation via the "Switching" objects (same
priority – last switching command is executed – cf. fig. 12). Hence, all 'secondary' functions such as
timing or additional functions are considered as well.
Enabling the central function
Enable the central function on the "General" parameter page by setting the "Central function?"
parameter to "Yes".
When the function is activated, the "Switching central function" communication object becomes
visible.
Assigning groups to the central function
Each DALI group can be assigned independently of the central function.
The central function must have been enabled on the "General" parameter page. Otherwise, the
assignment will have no effect on a group.
Set the "Assignment to central function ?" parameter in the "Groups – [x] group name – switching"
parameter node (x = group number 1...32) to "Yes".
The corresponding group is now assigned to the central function. The assigned DALI devices can be
switched on or off from a central control station.
The switching status set by the central function will be tracked in the feedback objects and also
transmitted to the bus, if they are actively transmitting. The switching status set by a central function
is not tracked in the "Switching" objects.
After a bus/ mains voltage return or after an ETS programming, the central function will always be
inactive (object value "0").
