FEATURES

• Configuration via Browser, telnet or serial port
• Enable serial DNP-3 devices to communicate with a DNP/TCP or DNP/UDP host computer
• SNMP agent functionality
• Protocol aware: minimum configuration needed
• Two serial ports that each support RS-232, RS-422, RS-485 2 or 4 wire
• RS-422/485 version with optical isolation available
• 10 or 100 Mbps ethernet
• RS-232 interface speeds to 230 Kbps
• RS-485 Bus mastering for two independent poll strings
• DIN rail or wall mounting

DESCRIPTION

Normal operation would consist of one or more ethernet based computers functioning as DNP-3 host and one or more DNP-3 slave devices (usually RTUs) connected serially to the gateway.

The EDNP-3 enables one or more DNP-3 ethernet based controllers to communicate with DNP-3 based serial RTUs. It will not allow DNP-3 IP RTUs to operate with a serial DNP-3 controller.

By using RS-485, multiple DNP-3 slave devices may be connected to each of the two serial ports on the EDNP-3. If using RS-232, one DNP-3 slave device may be connected to each serial port.

The EDNP-3 is designed for mounting on a standard DIN rail, or for direct mounting on a wall. For easy connection to your LAN, the gateway supports 10BaseT or 100BaseT , half or full duplex with auto-sensing or pre-configuration.

For other applications (point-to-point direct RS-232 links or point-to-multiple point "dialed" links via ethernet ) see the EtherPath single port serial server. The EtherPath uses TCP/IP.

A companion product, the EtherPoll is appropriate for applications using other protocols. The EtherPoll is protocol independent, and requires no knowledge of the RTU protocol. This allows it to work with any asynchronous byte-oriented protocol with no additional configuration. The EtherPoll uses UDP/IP. It's data sheet is here.

The EtherGate is another companion product that is protocol-aware (both Modbus and DNP-3). It enables serial SCADA devices to communicate via an ethernet network. The EtherGate is ideal for transporting SCADA protocols via ethernet. To transport SCADA protocols over Frame Relay circuits (without ethernet), use the DCB BPF Scada-FRAD.
