I think I should have some misconception and I do appreciate if anyone can clarify me.
According to https://techsupport.osisoft.com/Troubleshooting/KB/KB01128 , in section "Sample Request", three queries
would need to query for getting the Snapshot:
1. Use the Search API to obtain the WebID of the Element.
2. Use the Element API to obtain the WebID of the Attribute.
3. Use the Stream API to request the Snapshot Value.
(Above reference has mentioned Step 2 and Step 3 can be combined to one step by using "response.Items.Links.Value".)
I would like to ask is it possible to make a single query to replace above 3 steps which can get the Snapshot Value, assume the point
(for PI Server Tag Point) or element (for AF Server Tag) is known in advance? e.g. (Below syntax is wrong. If it is possible, I want to
know the correct syntax.)
(according above reference) https://localhost/piwebapi/streams/[elements?path=\\MYPISERVER\NuGreen\NuGreen\Houston\Cracking Process\Equipment\B-210|Fuel Gas Flow]/value
Thank you all for your kind attention.
