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.

Hi Bhadresh,
Using the subscription mechanism will help you with the report generation.
You will list all the tags that you need and you subscribe 5 mins before you run the report and you unsubscribe 5 mins later.
You may use 2 other reports to achieve this to make sure that the subscription is with the Report server.
Regards
