OPCUA Process Gateway deadlocks after reload

OPCUA Process Gateway deadlocks after reload

Summary

The OPC UA Process Gateway does not work as expected after a full reload of the Service Engine. This problem has been fixed.

Description

If endpoints or communication parameters for the OPC UA Process Gateway are changed in the Engineering Studio, a full reload is necessary in the Service Engine. This involves closing and re-establishing the client connection. After a full reload, a deadlock may be displayed in the Windows task manager when analyzing the wait chain for the zenProcGateway.exe. In addition, depending on the zenon version, further errors can occur, such as: localeIdArray is not available in the server node, alarms cannot be queried and/or authentication fails because the user information is not available.

This error has been fixed. The OPC UA Process Gateway now works as expected again after a full reload and all functionalities are available.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 10 or higher.
