History Logs have been configured to reflect short term History (2/3 weeks). Configuring long term history logs is using a lot of space in the hard drive.
In addition he is using 3rd party Historian Server (Aspen InfoPlus.21) as a long term Historian Server, but he would like to be able to read this data in the 800xA, if this is possible, and see the long term history in the trend displays.
Does anyone knows if there is a posibility to get data from InfoPlus.21 from any ABB 800xA Service?
Are you asking if it's possible to have 800xA pull data FROM IP21 (for example, for operator trends), instead of using 800xA basic history data or 800xA IM data? I'm not sure that's possible... but if hard drive space is an issue, we typically use separate physical hard drives dedicated for basic history storage.
