G 3800 X036 Operation Manual
August 2006
The External Reference list defines for the Mastergenerator, which addresses in the overall system shall act as
inputs to the function assigned to the address the list belongs to (in the above example the list belongs to
address C1). The input status of all the addresses on the list are OR’ed together with the input status of the
address the list belongs to. In other words, if one of the addresses on the list or the local address has an active
input, the Mastergenerator will regard the local address as having an active input when calculating the output
status for the address.
Example 1:
If in the example above, address C1 is defined as "toggle switch" for light control, then the output C1 can now
be toggled in 3 different ways:
1. The usual way by activating a pushbutton with address C1 in the "local" Dupline network
2. By activating the D6 pushbutton in the Dupline network with ID no 3
3. By activating the B7 pushbutton in the Dupline network with ID no 5.
Example 2:
In a 3-floor building, there is a Dupline network on each floor controlling the local lights. It is desired to have a
pushbutton on the lower floor for turning OFF all the lights in the building. The Dupline network on the lower
floor has ID no 1, the middle floor network has ID no 2, and the network on the top floor has been defined as
RS485 Master (see sec. 4.5) and therefore has ID no 32.
Parameter
Description
Net No / Channel
Whenever an external reference needs to be added or removed from the Ext.
Ref. list, the Dupline network ID and the Dupline address needs to be entered
here.
2.7 Reference to data from other Dupline networks
2.7.1. General
When several Mastergenerators are linked together in an RS485 network (see section 4.5), it is possible to
include signal status from other Dupline networks in the intelligent functions. This can for instance be useful in
a big building with several Dupline networks, when all the lights need to be switched off by activation of just
one button, or when all the roller blinds need to roll up when the wind sensor connected to the Dupline net-
work on the top floor measures a too high wind speed. In practice, there are three ways to make a reference
to addresses in other Dupline networks, "External reference", "Read external Input" and "Status Indicator".
2.7.2. External reference
All the objects, except for the "Analog Sensor", have a button, located just below the description field, for
selecting "Ext. Ref." When this button, is activated, a list pops up where it is possible to add or remove
references to addresses in other Dupline networks. In the example below for address C1, external references
are made to address D6 on the Dupline network with ID number 3, and to address B7 on the Dupline network
with ID number 5.
