sql sql-server historian aspen

I will be given access to an AspenTech InfoPlus 21 endpoint, but the systems seems to be quite legacy and not very well (publicly) documented. I will need to query some data (i.e. explore what is in the database). I had a few questions regarding connecting and querying InfoPlus 21 historians.

  1. How can I connect to the InfoPlus 21 server (in the best case programmatically)? I am mostly using mac, can use linux and windows through a VM. Really, and ideas for working solutions are welcome.

  2. How can I query data from InfoPlus 21 (in the bet case programmatically) and what does the data look like? Any pointers etc. would be very helpful.

I have some experience using NoSQL (mongodb) and SQL (postgres and mysql) databases, but couldn't really find anything useful for aspentech infoplus 21 on the web. Any help would be greatly appreciated.

InfoPlus21 is process historian containing list of templates of different tag structure e.g. IP_AnalogDef, IP_DescreteDef, IP_TextDef etc. Based on process tags from DCS/OPC/Any other historian, the IP21 records are created and each record acts as a table in historian.

ANS1: Aspentech software is only windows based compatibility however IP21 aspenONE Process Explorer is web based and therefore you can access it over any operating system using host url.

ANS2:

you can try SELECT statement to get data from IP21 Historian using it's end-user component SQLPlus or on excel add-ins. e.g. 

SELECT NAME, IP_DESCRIPTION, IP_PLANT_AREA, IP_ENG_UNITS FROM IP_ANALOGDEF

RESULTS: RESULT OF ABOVE QUERY

I hope this help you understand better. Otherwise you need to first learn the structure of your IP21 historian tags to build the query e.g. If it has customized structure, then you have to build your own.
