***Important notes before configuring WIN-911***


Please review the System Requirements page for supported SCADA versions and other helpful information.




OPC DCOM Settings


DCOM or Distributed Component Object Model is used primarily for the allowance of communication between clients and (OPC) servers with the same computer that runs the Windows OS. It allows COM components to communicate among objects on different computers. DCOM uses Remote Procedure Call (RPC) to allow COM to communicate beyond the boundaries of the local machine to a remote machine.


Out of the box, your OPC server will most likely not work or connect with WIN-911. You will need to configure DCOM for your environment so that you will have the proper permissions to access, connect, and communicate from WIN-911 to your OPC server.


The instructions on how to perform DCOM settings can be found with the following link, based on your Windows OS: DCOM Setup.





*** WIN-911 Configuration ***



In the WIN-911 Workspace, expand Alarm Sources > OPC Alarms & Events > Click Add New Configuration.



Fill out the corresponding fields in WIN-911, to connect to the OPC Server.

Name: Enter a name for your OPC A&E data source.


Machine: Select whether the OPC A&E server is installed and running on the same Local machine as WIN-911 or on a Remote machine (if remote, enter the IP address or hostname. The server will need to be reachable across your network.)


Server Class: Click the ellipsis button (3 dots on far right) to browse for the server class on the selected machine. Choose your correct OPC A&E server from the list. 


IMPORTANT: Browse functionality for available OPC servers is dependent on OPC ENUM being properly configured on both the WIN-911 machine and the OPC server machine. See "OPC DCOM settings" above.





OPC A&E Alarms are configured in the OPC A&E Server and they are brought into WIN-911 through the use of subscriptions. 


Create a subscription by clicking the + Add Subscription button.




Enter a name for the Subscription and select which Notification Policy it should be routed to.



Define the criteria this subscription should filter for.


Qualified Source Name: This is essentially the fully qualified tag name string in the OPC A&E server.

Filter using - Wildcard, Regular Expression, Contains, or Does Not Contain.




Category: This is defined in the OPC A&E Server. It should be a string and ID number pair. (Example: ID 3 - Level Alarms).


Filter using - Wildcard, Regular Expression, Contains, or Does Not Contain. 




Severity: Select a range or specific value that matches the severity of the alarm(s) you want to catch with this subscription.



You can add additional criterion and filters using the AND/OR operations to create more complex search patterns. 





And always... Save your changes!






Watchdog (Optional) 


WIN-911 has the option to configure a watchdog to check if it can still communicate with the OPC A&E server. This will monitor a supplied Node Name for changes. If no changes are detected within the configured timeout period, WIN-911 will generate an alarm.  


Enter a name, enter or browse for a Node Name to monitor, select the timeout interval, and choose which Notification Policy to use for notifying.
