Hi,
We use clear scada 2010 R1 in CCR and Siemens S7-1200 PLC in remote site communicating via dnp3 protocol via gprs modems , the issue we face is in the pump running trends which are not updating in the scada all time,also the pumps running trends are not matching with the level and flow trends in the site. Is there any issue in the data buffering of the plc or any settings to change in polling of sites to make it normal.

Are the pump trends fed directly from DNP3, or are you using an Accumulator object? If the latter, you could use the Continuous option, but that will read incorrectly if your modem fails to connect. Really you can't expect live displays from a GPRS source.
