1.9 OPC Alarms and Events interface
The OPC Alarms and Events interface provides information about the
status of output unit channels and DALI ballasts. A C-Bus network may
contain Error Reporting compatible units, all of which are reporting the
status of channels or DALI ballasts across the C-Bus.
Error Reporting applications supported
The Error Reporting application is used to report error information
detected or generated by certain C-Bus units over the C-Bus network.
C-Bus units may monitor and detect error conditions, and report those
conditions using the C-Bus error reporting application.
The reports contain information on the source, severity and nature of the
error or fault condition. The status of an error is reported as OK when it is
operating normally.
Devices that receive error reporting messages act upon the information in
whatever manner is appropriate. This may include publishing information
for a user, logging errors or sounding alarms.
C-Bus units which support Error Reporting application
The C-Bus units and Clipsal software which support error reporting are:
 DALI gateway ( Unit types: PC_DAL2B, PC_DAL2C)
 C-Bus Universal dimmer
 3 channel architectural dimmer
 6 channel architectural dimmer
 12 channel architectural dimmer
 3 channel professional dimmer
 6 channel professional dimmer
 12 channel professional dimmer
The Error Reporting application messaging is processed into error
conditions which are stored as event and alarm states in the C-Bus OPC
Server.
Logging of OPC Alarms and Events data
The C-Bus OPC Server generates logging data during start/restart and
stopping event sequences as well as operational OPC transmission events.
A subset of the log information is displayed in the M ESSAGES tab. The full
log information can be read using SmartInspect logging viewer. The
location of C-Bus OPC Server log files is at:
C:\Clipsal\CbusOpcServer\Logs There are log entries with "OPC
AE" in the text for whenever events are sent, alarm conditions are
changed, acknowledgements are received from OPC Clients, and
acknowledgements are sent to C-Bus units.
