Odd Quality Values

Post by nifemi.ogundare »

Good day all,

My company recently purchased our first UA Gateway license. The installation was deployed on a windows 7 system with an OPC-DA server, and the data is being red from another OPC-UA server on a remote Debian 8 system. Initial results were good but after a few days, we are now receiving data with bad quality. Furthermore, the quality message is different depending on circumstances:

- when doing a normal one-time read, it returns the following:

Code: Select all

Quality: [Bad_OutOfMemory] Not enough memory to complete the operation.
- when creating a subscription, it returns the following:

Code: Select all

[Bad_NoCommunication] Communication with the data source is defined, but not established, and there is no last known value available.
All data values are NULL in both cases. In addition, we are still able to read extraneous server information data like connection state, server status, etc. with no problems.

Any assistance is appreciated, thank you.

As additional info, I am currently unable to access the UA Gateway logs because the gateway is installed on a controlled access system.

Hi,

The first question we have is regarding the setup. You wrote that UaGateway is installed on Windows 7 with a DA Server and that another OPC UA Server on a Debian 8 system is accessing the data from the DA Server through UaGateway. We assume the OPC UA application on the Debian 8 is an OPC UA client that is accessing the DA Server through the OPC UA Server of UaGateway? Is this right?

Regarding the UaGateway, can you check the resource consumption like used memory, threads, handles?

Are you still able to connect to UaGateway with another client e.g. UaExpert?
If yes, can you read the following Variable values and report them to us?
Objects -> Server -> VendorServerInfo -> ObjectStatistics (all Variable value in this folder are of interest).

Best Regards,
