Attention:
It is preferable for the third-party OPC servers to run in a dual active mode rather
than an active-passive mode.
Experion OPC Advanced Data Client
The Experion OPC Advanced Data Client is primarily designed for integrating complex
subsystems, such as distributed control systems. Such systems typically have point-like
structures, that is, complex data structures. It is based on the OPC Foundation Data Access
Specification Version 2.05.
OPC items are mapped to OPC advanced points. You build OPC advanced points in Quick
Builder. The OPC advanced point allows you to create arbitrary point parameter names to
reference OPC items. The OPC advanced point also allows you to have more than 8 scanned
parameters. The scanned parameters can also have user-defined names.
After you have built your OPC advanced points, you can add these points to trends, custom
displays, group displays, just as you can with other point types in Experion.
If you want alarms, you need to use the OPC Advanced Data Client in conjunction with the
OPC Advanced Alarm And Event Client.
Experion OPC Advanced Alarm and Event Client
The Experion OPC Advanced Alarm and Event Client enables Experion to receive alarms
and events from third-party OPC alarm and event servers. It is based on the OPC Foundation
Alarm and Events Specification Version 1.0.
OPC alarms are displayed and acknowledged in the same way as Experion alarms, giving
operators a uniform user interface. For example, when an OPC alarm is received, it appears in
the Alarm Summary; and when an operator acknowledges the alarm, confirmation of the
acknowledgement is sent to the OPC alarm and event server.
