1.1 Why have a C-Bus OPC Server?
An obvious reason for installing and operating a C-Bus OPC Server is
because you want to incorporate lighting application data from C-Bus
networks as part of a building management solution.
The C-Bus OPC Server makes it possible to transmit Lighting Type
application messaging between a C-Bus network and a OPC Client. The
messaging can:
 transmit the lighting status and levels to the OPC Client from a C-Bus
network
 control the lighting status and levels by sending lighting commands
from the OPC Client to the C-Bus network
 show C-Bus network status, indicating if the status is OK or if there is
a problem
 The C-Bus OPC Server also makes it possible to monitor the status of
Error Reporting.
C-Bus OPC Server brings C-Bus building management connectivity
The graphic below illustrates how the C-Bus OPC Server can be part of a
larger building management system collecting data for C-Bus lighting
applications and other subsystems networks such as HVAC and security.
