[IOServer]DisableConnectivityPropertiesAndExtensions

The Connectivity Server manages tag subscriptions for the OPC UA Server and the Industrial Graphics Server, and passes these subscriptions on to the I/O servers. The tag may be in the format of either TagName or Equipment.Item.

If a subscribed tag also specifies a property or extension, extra processing is required by the I/O server. The greater the number of I/O devices, the greater the processing load.

If your project does not require properties or extensions for the OPC UA Server or the Industrial Graphics Server, then support for these can be disabled. This will improve the performance of the I/O servers.

This parameter is only available globally and cannot be set per individual I/O server. For consistency in behavior, it is recommended that the INI is applied uniformly across all computers in your system.

Note: This parameter only applies to subscriptions from the Connectivity Server. It has no relevance to subscriptions made from alarm, trend or report servers, or from Plant SCADA clients or web clients.

Allowable values:

• 0 — properties and extensions are enabled

• 1 — properties and extensions are disabled

Default Value:

0
