Hello everyone!
I have a documentation-related question regarding an interface we're building to connect our software to the PI system: Is there any "official" template, some best practices, or at least a good example for such an interace specification document? It is the document we'd like to provide to our customers with the required instructions to set-up and maintain the system.
Thanks all for the responses in advanced!
Hello Valentin,
At OSIsoft we use the term Interface for data adaptors that collect data from data sources like DCS systems or 3rd party databases. PI Interfaces support a certain communication standard like e.g. the PI Interface for OPC DA supports the OPC DA standard. Some Interfaces support not just read but also write operations. While Interfaces write against PI Points, the next generation referred to as PI Connectors work Asset Centric. Please refer to PI Interfaces and PI Connectors.
After visiting your companies homepage, my impression is that you like to create a custom data adapter for your visualization and analysis product which consumes PI Server data. Is this the case? If so, your ask is likely what operations your custom data adaptor should support and I believe the answer is this depends on what information your application needs and e.g. how flexible you like to design it to allow adoption to existing installations. I am afraid you will have to ask more specific and share more details of what you are planning to do to enable us providing you with useful guidance.
