Introduce a PI OPC UA Server
The OPC landscape is shifting away from DA/HDA and towards UA servers. A significant number of OPC client tools are being created that connect to OPC UA servers, and none of these are compatible with PI without the use of a third party UA wrapper since we only provide DA and HDA servers.

shared this idea
We have been gathering use cases and information about OPC UA Server functionality as it pertains to OSIsoft products.
There are a number of different requirements to consider, and as such we’re changing the status back to “UNDER REVIEW / RESEARCHING” to more accurately reflect the current status of the work.
At this time, we are not committing to bringing this capability to market.
We will update this thread if the status changes.

Glencore Coal - Clermont Mine have requested an OPC UA connector to PI for a third party application to do analysis based on PI data using OPC UA

I have a customer calling today expressing interest in getting data out of their vendor's OPC UA client into PI.

I have a few customers requesting this functionality too as they need to expose their operational data to other UA brokers.

Given that OPC UA is a developed standard data exchange protocol in the marketplace, and the evolution of COM based OPC, it should not be dependent on use cases to drive development; supporting the import AND export of data via OPC UA should be in our product portfolio by default. Customers outside of the US are becoming heavily invested in OPC UA connectivity to integrate equipment to time series databases, equipment that is less integrated with control and more Industry 4.0/IoT centric. Increased focus on security necessitates this change as well since OPC UA is inherently more secure than COM based OPC. Cloud based technologies are leveraging OPC UA as a standard mechanism for data exchange to and from on premise systems. While we tout the fact that we support over 200+ interfaces and have built over 500 in our history, OPC has by far been the biggest seller over the past 15 years and OPC UA connectivity is naturally poised to take over the top spot. We have multiple large opportunities that will be assisted by supporting the movement of data with context in and out of PI via this technology, so we need to support it in both directions.

Both Dow and Whirlpool are requesting the OPC UA Server. Whirlpool would like to expose data from PI to Ignition via OPC UA. Dow uses OPC UA as a common integration protocol to their business systems. Happy to schedule a meeting with product development and the customer to discuss further.

Inductive Automation has a UA Client that would utilize this : OPC-UA Connections and Settings - Ignition User Manual 7.9 - Ignition Documentation
This link has the connection information you may need for testing with there demo. -

Please you have to include security.To have the ability to set access rights to OPC clients, not everyone should be able just to use a client an access the OPC.

The main requirements is that the OPC UA does not require a specific requirement, it is an industrial protocol that finally bring all OPC functionalities in an unique framework and platform independent, also represented with an international standard - IEC62541. Many business applications leverage on the real time data, the most recent is the IoT and the OPC UA server capabilities make them easily accessible for instance...

Fully agree! the PI must be able to work with the OPC UA server specifications;
in order to meet the cyber security requirements as well. -

Ideally, would want to use Pi as BOTH an OPC / UA client and server.
From a client perspective, the Pi OPC / UA connector could be used to either poll OPC / UA based comm mgmt. servers (like Kepware) or subscribe to published events via OPC / UA from comm managers capable of that or eventually edge based PLCs, etc. that can act as OPC / UA servers.
From a server perspective, once data is collected into PI Server, would like to be able to stream it (via OPC / UA over MQTT or AMZP) up to an IoTHub in Azure for more advanced analytics. It looks like this piece may be doable in the upcoming version of the Pi Integrator for Azure. -

In response to Ray's comment asking for OPC UA Clients. One use case I have heard from customers is to expose PI data via OPC UA to Siemens SINCAL.

We have a need to Access AF elements via an OPC UA Server.
We have third party software that gets it's data via an OPC DA Server, and that tool refers directly to Tag names.
Those names could possibly get modified and cause many edits in the third party application, this situation has already occurred at least once.
If we could point the third party tool to use AF Elements, exposed via the OPC US Server, then the third party tool would no longer need to change if tag names changed. -

Balamurugan they don't have a road map yet. If you need to implement soon you need to look into using an OPC UA Wrapper. -

We need to expose PI as OPC UA server for one of the large scale implementation project. Does OSISoft has any roadmap?

Fully agree, the PI System should have the possibility to work as an OPC UA server.
