1. Introduction
1.1. DNP3 Introduction
DNP3 (Distributed Network Protocol 3) is a communication protocol used
between automation components. The protocol is formulated with
reference to IEC 870-5. The purpose is to unify the communication
method of SCADA so that SCADA can use the DNP3 protocol to
communicate with master stations, remote terminal units (RTUs),
intelligent electronic devices (IEDs), etc., and are mainly used in utilities
such as electric and water companies.
The DNP3 protocol has certain of reliability and allows reliable
communications in the adverse environments that electric utility
automation systems are subjected to being specifically designed to
overcome distortion induced by electromagnetic interference (EMI),
aging components, and poor transmission media. A large number of CRC
check codes are used in the protocol to ensure the accuracy of data. It is
suitable for high security, Data communication field of medium speed and
medium amount of data.
1.2. Modbus TCP Introduction
Modbus TCP is a variant of the Modbus family of simple, vendor-neutral
communication protocols intended for supervision and control of
automation equipment. Specifically, it covers the use of Modbus
messaging in an “Intranet” or “Internet” environment using the
TCP/IP protocols. The most common use of the protocols at this time is
for Ethernet attachment of PLC’s, I/O modules, and gateways to other
simple field buses or I/O networks.

1.3. About DNP-211
DNP-211 is a gateway that supports DNP3 master and Modbus TCP
server protocol conversion. As long as the master device supports
Modbus TCP protocol, it can connect the existing DNP3 network with the
Ethernet-based master device. For DNP3 network, DNP-211 is a DNP3
master device. It supports several commonly used data groups and
variables and can communicate with slave devices. From the perspective
of Modbus TCP network, DNP-211 is a Modbus TCP server, which can
receive commands from Modbus TCP client, and process these
commands to reply or send related DNP3 data. All DNP3 I/O data and
Modbus mapping can be configured through DNP-211 utility software.

3. Getting Started With DNP-211
3.1. Preparations for Devices
In addition to the DNP-211, please prepare the following:
1. Power Supply: +12 ~ +48 VDC (Ex: DP-665)
2. Ethernet Hub or Switch (Ex: NS-205)
3. PC/NB: Can connect to the network and set the network
3.2. Hardware Wiring
Connect the DNP-211 with the RJ-45 Ethernet port LAN1 to an Ethernet
hub/switch and PC. You can also link directly the DNP-211 to PC with an
Ethernet cable.
After power is connected, please wait 1 minute for DNP-211 start-up
procedure. When the "RUN"indicator starts flashing and “PWR”
indicator is constantly lit, it represents the boot is complete. After the
module boots successfully, if the "L1" indicator flashes every second, it
means the firmware is running.
