6 Programming Methods
(cont’d)
Method 1, Individual Unit Programming
The Units are initialized one at a time, on-the-bench or in an oce environment.
The Units may or may not be fully programmed at this stage. Any programming
variables may be entered, including control relationships, and then the Units are
installed into the building. It is important that the contractor uses the labels provided
with the C-Bus Units to record the Unit Address, Network and Part Number (Part Name),
such as location, to ensure correct placement of the Unit on site. Once installed, any
further programming changes can be entered, and the installation may be commissioned.
It is important that each module has a unique Unit Address otherwise unpredictable
behavior may result.
Method 2, Programming The System In-site
The Unit Addressing may be programmed on site, one Unit at a time, as they are
installed. The installer should mark the label provided and attach it to the Unit, with
the Unit Address, Network, Part Number, and location. All other programming variables
are then entered, including control relationships.
Method 3, As Installed Programming
In this method, all Units are installed into the building, unprogrammed. Factory default
settings of the Unit Address for all products in the C-Bus range is 255. The Network
will exhibit unpredictable behavior at this stage, since Unit Addresses will not be
unique. The C-Bus Toolkit Software v3.0 incorporates a new Network Unraveller
facility. This has the ability to detect and resolve Unit Addressing conicts automatically
during a Network scan. The Unraveller has limited capabilities, and should not be
relied upon to unravel large Networks at the time of installation.
This method has the advantage of not requiring any pre-programming of C-Bus Units,
however this comes at a price. Once the Network has been unravelled, and a unique
Unit Address assigned to all Units, each must be located and identied within the
installation using the labels provided. This process may be aided using the Quick Toggle
facilities built into the Installation Software, but can be cumbersome for larger Networks.
The installer should mark the label provided and attach it to the Unit, with the Unit
Address, Network and Part Number.
With the Units installed, and with each Unit having a unique Unit Address, each Unit
may in turn be interrogated on the C-Bus Network, and the operating parameters and
control relationships programmed into it. Individual Unit programming, programming
the system in-situ, or as installed programming may be used, but each method is prone
to misuse and error. If the Unit Addresses are incorrectly programmed or if the equipment
is incorrectly placed in an installation, unpredictable behavior may result. The designer
and installer must ensure the planning process and installation documentation are
correct, and the placement of the equipment proceeds in a systematic manner.
Identication labels should be used on all C-Bus Units. The templates have been
produced to simplify the task of allocating Addressing information and assist in the
programming methods as recommended by Clipsal Integrated Systems.
Labels are included with PC Interface and Network Bridge Units. Completed labels can
be stuck on to the rear of the product. Alternatively, the label may be adhered to the
front of any wall mounted Unit (such as a Key Input Unit) for easy reference without
the need to remove any screws. In this case the label should be positioned on the
edge of the grid plate such that it will be covered by the surround when snapped in
place. Key input plates may also be labeled according to key function, or controlled
load, for the benet of the user. 2000 Series and metal plate input Units may be hot
stamped or engraved as appropriate. Classic (C2000) Series plates incorporate a small
label window. Typical label examples include ‘Warehouse’, ‘Oce’, ‘Entry’, ‘Welcome’,
‘Goodbye’, and ‘Party’. Contact your local Clipsal sales representative for more information.
C-Bus Learn Mode
Learn Mode is designed for contractors to program small to medium scale systems
without the use of a PC. This method is well suited to small networks, with simple
functionality. Networks with a large number of devices and complex functions should
be programmed using the C-Bus Installation Software. Learn Mode is activated by
pressing the manual override keys on an output unit for a predetermined time. For
more information on programming Learn Mode see the following section for an in
depth guide.
