Importing an XML type definition file into Security Center - OPC Client 3.1

OPC Client Plugin Guide 3.1

OPC Client 3.1

To import OPC tags from an OPC server into Security Center, you must import the type definition file into the OPC Client plugin.

What you should know

The XML file is validated when the plugin starts.
IMPORTANT: The entity type definitions in the XML file are stored in the plugin database. After the XML file is imported, the entity types cannot be modified or deleted from Security Center by modifying or deleting them from the XML file.

To delete or modify imported entity types, you must delete the plugin role and its database, create another instance of the plugin role, and create another XML file.

To add new entity types to Security Center, update the XML file to include the entity types under a unique name, and then reimport the file.


  1. Copy your XML file to the OPC Client Extensions folder on the plugin server.
    The default location is $\Program Files (x86)\Security Center Plugins\OPCClient\Extensions.
  2. If the OPC Client plugin role is already created, deactivate and then reactivate the role for the entity types to be loaded.
  3. After the OPC Client role is created, verify that the Generic extension is loaded on the Extensions page of the OPC Client plugin.


Clicking the Generic extension displays the entity types and property information defined in the XML type definition file.

After you finish

Create a CSV import file.
