Using OPC DA, software applications can retrieve real-time data to enable them to monitor a given process. Resolved an issue where the driver would invalidate tags if the remote server did not provide a supported data type when the item was added to the server. The driver will now wait for the first update before invalidating unsupported data types.

Fixed an issue in the Tag Import Browser where parent node tags would be imported even when only a child node was selected.

Available Languages English. NET Version 1. Release Notes 6. Fixed an issue when trying to write to tags before they are added to a subscription. The driver rebuilds the connection if the device level group fails to add, similar to a shutdown notification, status, or watchdog failure. Fixed an issue where consecutive writes of the same value could result in bad tag quality. Resolved an issue where removing invalid items could result in a hang of the runtime.

Asynchronous Read and Write methods are the default and remain the optimal choice for most applications. Resolved an issue that could cause tag reads using ReadMaxAge to always read from cache. Resolved an issue that could cause the client to receive a newly written value, then a stale cached value, before receiving the new value again. It will now import these tags using the Default data type, and will also post a message to the Event Log.

Fixed an exception that would occur when invalidating tags while unloading the driver. Fixed a reconnect issue where the shutdown sink flag was not cleared.

Fixed an issue where valid data change events were thrown away because the driver received data change events on items before they were fully added. At this moment, this setting is not user-configurable. Fixed an issue wherein the initial update was not passed on to client applications. Removed the limit that prevented the creation of nested groups with depth greater than 8. Previously we would keep attempting to read the tags, expecting an initial update. In the case that the tag is invalid, we won't receive an update, and should report the tag is Bad: Out of Service.

Improved performance of ATG. The driver now removes all items from the underlying server when the DA Client's device is configured as disabled. Fixed issue where the driver returned an invalid read value when an item did not receive an update from the DA Server. We now continue to process the read request until we have a valid return value.
