DNP3 Communication Driver

DNP3 Communication Driver is intended for data connection between Reliance's runtime software and devices communicating via DNP3 (Distributed Network Protocol). The driver implements services for data reading/writing and time synchronization.

According to its parameters, it sends requests for current data from individual priority classes. It processes both data with no time stamp and time-stamped data.
