How to collect MIN, MAX, AVG mode on more than 128 TAGs ?

Hello,

we are using a inSQL connector to connect to an Historian DB.

Thru this connector we define a TAG Query in order to retrieve the needed data regarding the requested TAGs.

This TAG query allow us to request the DB in different modes : Current, GroupList, History,
HistoryEvent, ModeList, Statisch, TagList on which we devine a method : MIN, MAX, AVG, TOT, MIN MAX AVG, MIN MAX TWA, AVG SDV, TWA
SDV .

This TAG query is limited to 128 TAGS while we need much more TAGs in our project.

The idea is to do it thru a PCo Query thru a inSQLPCo connector to connect to the same Historian DB.

Thru this connector we can define a PCo Query to collect all the needed data. But we only have the mode :GroupList, ModeList, TagList, TagRetrieveQuery et ViewList, which does not allow the MIN, MAX, AVG etc.. which are needed !!!!

Did you already face such issue ?  How did you cope with it ?

Thank you for your support.

Hi Marc,

You should contact SAP regarding this.

Looks like a bug.
