8. About Supplied Software BZR-IF810
8-1. Outline
The S-BUS subnet controller software BZR-IF810 is
software installed on the routing switcher controller
HKSP-R80 to construct an S-BUS subnet. The HKSP-R80
on which the BZR-IF810 is installed is referred to as an S-
BUS subnet controller in this manual.
8-1-1. Features
BZR-IF810 enables you to increase the number of units to
be controlled in an S-BUS network and at the same time to
reduce the response time by decreasing the apparent
number of units to be controlled from the primary station.
It also offers functions to separate communication using
subnets.
Increasing the number of units controllable in an
S-BUS network
An S-BUS network can include up to 253 subnets, each of
which up to 253 units can be connected to.
n
If all stations, ID number 2 to 254, are extended, some
60,000 units can be controlled at a time. The time for
setting up a system increases as the number of units to be
controlled increases.
Flexible and reliable distributed processing
environment
The BZR-20 enables you to back up and restore setting
data for each subnet. It is also possible to have the bus
protection of the primary station and subnets in common.
When HKSP-R80 and HKSP-R81 with BZR-IF810
installed are used, tandem operations are available.
Integrated setting and data management for a
whole system
The BZR-2000 (optional) allows you to make settings for
all the units and back up the setting data at a time.
Distributed processing and integrated processing are used
as follows:
. Setting of the units in a subnet from the subnet terminal
. Setting of the whole network from the system terminal
HKSP-R80
n
If system setup is performed with the BZR-2000 of version
earlier than V1.40, only the remote panel and the UMD
(Under Monitor Display) can be used for extension.
Improving the response time for operation and
display
Response time for tally data sent to the UMD is improved
by distributing the communication load.
