Store & Forward for PI Adapter for OPCUA: Not working as expected

I am using a PI Adapter for OPC UA, collecting data every 15mns and sending it to a PIServer.

I want the system to be robust in case of network failure. Indeed my PI Adapter for OPCUA and my PI Server are on two very far machines.

I tried to shutdown my network connectivity for 1 day and then connecting it back. Even though I configured a very large buffer, I retrieved only 3h of data on my PIServer.

How should I configure it to be sure that, even in the case of network-crash, my data will be forwarded back to my PIServer and I will not have any gap of data.

Thanks,

Parents

Hi vmontmirailSE ,
Have you configured the MaxBufferSizeMB parameter? If not, it's default value will be set to 1GB.
The relevant documentation is here, Buffering (aveva.com)

Hello, I set it to 1GB indeed. Is there any other configuration somewhere? I am expecting something like "Do not store more than X-h of data" that could cause the issue.

Unfortunately, there is no other configuration for Adapters. You should be able to set this config very high. Adapters generally won't be able to know about X-hours of data because for every customer this will vary on its ingress rate and the number of tags.
