CPTT and the DNP3 family

DNP was originally developed by Westronic, Inc. (today General Electric). Since 1993, the [ DNP User Group ] is responsible for the further development of this protocol.

Originally the procol was called "DNP V3.00". Today the official name is "DNP3".

The DNP3 protocol family is widely used, particularly in the American/Pacific region.

DNP3 serial

DNP3 serial is used as a general transmission protocol between control systems and substations (RTUs, Remote Terminal Units). It has general abilities within the context of SCADA applications.
The messages are generally transmitted through serial connections. The frame format is abutted to FT3.

COMPROTware:Testtool offers in this protocol:

Simulation of Master and Slave Station.
Extensive state engine to implement protocols.
Monitoring on the serial line.
Interactive input of messages.
Different application oriented view formats for message traffic.

DNP3 over LAN/WAN

DNP3 over LAN/WAN is intended for connections through internet protocols. Both TCP/IP and UDP/IP can be used as transport layer. DNP3 over LAN/WAN has the same messages and the same frames format as DNP3.

COMPROTware:Testtool offers in this protocol:

Simulation of Master and Slave Station through TCP/IP as well as through UDP/IP.
Extensive state engine to implement protocols.
Network Monitoring under MS Windows 2000 and Windows XP.
Interactive input of messages.
Different application oriented view formats for message traffic.
