Does anyone know if it is possible to add a new background DNP3 record without performing the unsolicit update part at one interval (say every 10 mins) and then only perform the unsolicit update at a less frequent rate (say 60mins) and have the 6 x 10min records get sent then. Does this mean I would use 2 x DNPUpdate instructions in my program? 1 to add the record and not send and the other to perform the update to the Master. In my application I am using a CR310-CELL220 and performing the DNP Unsolicited update over a cellular link with the SCADA master (ie. opening a socket to SDADA master server before doing the update)
