PI Datalink Query FInd last entry when tag contains certain string part

Hi,

I hope somebody would/could help me with this.

I want to find from a stringtag the lasted entry that is equal to a part of a string (CIP_MAN) during a start- and end time.

So fare I filter the tag with the following filter expression.

Instr ('NLOS:IBATCH:BE8913:BETA14:StateChange:GEIB', "CIP_MAN")

I had allready the following that did the trick but it has only an end time and it is looking to the first value back in time from this endtime but I wanted to stop the search at the start time. Because else it could be looking trough years of data.

PINCompFilDat('Tag';End Time;-1;

Instr ('NLOS:IBATCH:BE8913:BETA14:StateChange:GEIB', "CIP_MAN")

;0;0;"PISERVER";"auto")

I hope it is clear and that somebody could point me to the right direction.
