Status
The OPC Alarm and Event Server has the following states:
•
OPCAE_STATUS_RUNNING
•
OPCAE_STATUS_FAILED (not used for the moment)
•
OPCAE_STATUS_NOCONFIG
•
OPCAE_STATUS_SUSPENDED
The following applies to OPC Server for AC 800M:
•
When the OPC Server is started, the status is set to 
OPCAE_STATUS_NOCONFIG. 
•
When connected to at least one controller, the OPC Server status is always 
OPCAE_STATUS_RUNNING. 
•
If all controllers are removed from the panel, the OPC Server status returns to 
OPCAE_STATUS_NOCONFIG.
•
The system variable SetFailedAtNoConn is used to control the behavior when 
all connections to controllers are lost (for information on how to set this 
variable, see 
Setting System Variables
 on page 61):
–
The default value of SetFailedAtNoConn is True.
–
With SetFailedAtNoConn set to True:
If there are controllers in the panel, but all connections are offline, the 
OPC Server status is set to OPCAE_STATUS_SUSPENDED. As soon 
one of the connections is restored, the OPC Server status returns to 
OPCAE_STATUS_RUNNING.
–
With SetFailedAtNoConn set to False:
The OPC Server status is OPCAE_STATUS_RUNNING as long as there 
are controllers in the panel, no matter if they have a working connection or 
not.
