The DNP3 Serial Driver adheres to and supports the framework specified by the IEEEġ815-2012 Standard for electrical power system communications. When the FieldServer is a ServerĬan communicate to it. The FieldServer can emulate either a Server or Client. The DNP3 Serial driver allows the FieldServer to transfer data to and from devices over RS-232 or RS485 usingĭNP3 protocol.
