Read last good valid value with issuing new query by IOServer on MODNET protocol

Dear All,

I have a devices which communicate on MODNET protocol. I am generating report with lots of tags using default report-device feature. So i do not want to read (do not want to query all tags as all devices are on serial) all tags when i generate report. Means i want data which is available last.

Is there any option for this ?

I tried TagName.V , Tagname.Valid, Tagname.Valid.V etc but in every case IOServer is polling to serial device.
