AccessOPCUA does not clear session after configured time when client connection is lost

AccessOPCUA does not clear session after configured time when client connection is lost

Summary

In the Process Gateway the OPCUA server (AccessOPCUA) does not clear sessions in case of connection loss. This has been fixed.

Description

If the OPCUA server in the Process Gateway loses the connection to a client, a new session is started after reconnection. The session used before remains in use. It will not be closed even after the defined waiting time (default 600 seconds). As soon as the maximum number of sessions is reached, channels can still be opened, but no more sessions are available. The server responds with "BadTooManySessions".

 

This error has been fixed. The OPCUA server now terminates the session correctly if the connection is lost.

 

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 11 or higher.
