DNP-211

Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies. It was developed for communications between various types of data acquisition and control equipment. It plays a crucial role in SCADA systems. It is primarily used for communications between a master station and Remote Terminal Units (RTUs) or Intelligent Electronic Devices (IEDs).

DNP-211 is a solution that provides a communication transformation between DNP3 and Modbus TCP protocol. It can connect an existed DNP3 network with Ethernet-base master device as long as this master device supports Modbus TCP protocol. For DNP3 network, the DNP-211 is a DNP3 master device. It supports several commonly data group and variation communicate with slave devices. From the view of Modbus TCP network, DNP-211 plays a Modbus TCP server role. It can receive the commands from Modbus TCP client and process the commands to reply or send the related DNP3 data. All the DNP3 I/O data and Modbus address mapping can be configured via DNP-211 utility.
