Is it possible to connect a remote OPC UA/SQL server to a PI System in the cloud without Edge?

Let's say that I have an OPC UA and SQL server on premise which have internet access. My PI System is in my own cloud environment where the AF and DA are in 1 VM, SQL and Web API are in another VM.

 

1) Is it possible to connect my OPC UA and SQL servers to my PI AF/DA machine in the cloud?

2) If so, is it okay to install the PI Adapter for OPC UA and PI Adapter for RDBMS on my PI AF/DA machine to retrieve data from my OPC UA and SQL servers (instead of installing them on the OPC UA/SQL servers)?

3) Is PI Web API required then? Or is it okay to set egress of the PI Adapter to the port in which the PI DA is installed in.

 

Any information on this is appreciated, thank you!

  • Hi,

     

    1) Anything is possible… Sorry to be snarky, but as long as the on-prem machines can “see” the necessary ports on the cloud machines, then you should be good to go.

    2) It is OK, in a sense that it should work, but my understanding is that best practice is to put the adapter as “close” as possible to the data source(s). In your case, these are the two on-prem machines. If it's not possible to co-host the adapter in the same machine as the data sources, then a good option is to spin a little VM in your on-prem data centre (same DC as where the SQL and OPC boxes are).

    3) WebAPI is a mandatory requirement for using the adapters to write data to PI Server (https://docs.aveva.com/bundle/adapter-for-opc-ua/page/1227826.html).
