How does a group function?
A group means the combination of group addresses whose assigned
communication objects should be influenced in the same way when an event
occurs.
It is defined in the time switch program when telegrams are sent on the bus
with specific group addresses and specific values.
If several telegrams with specific group addresses and specific values
should be sent repeatedly at specific times, they can be combined into a so-
called group e.g. the lighting in room 1, room 2 and room 3 should be
switched on repeatedly at 15:00, 16:00, 17:00 and 18:30 and the blinds in
room 1, room 2 and room 3 should be lowered.
The group addresses and values assigned to these functions can now be
combined into a group e.g. with the name "Room 1, 2, 3". You can therefore
designate a group as a functional group and the combined group addresses
as group members.
It is then only necessary to enter the group address of a trigger of this group
in the time switch program e.g. with the name "Room 1, 2, 3" in order to
send telegrams on the bus with the group addresses combined in the group
(group members) and values.
The group address which triggers a group is called a group trigger.
This saves time during the parameterisation and the time switch program
becomes clearer.
If a group is activated, it sends telegrams with the group addresses which
are contained in the list of group members and with the values which are
assigned to these group addresses.
Several group addresses with different types can be combined together into
a group.
