EtherSeries DNP- 3 Gateway User’s Guide
EtherSeries EDNP-3 Functions
The gateway allows serial DNP-3 RTUs to communicate and
interoperate with DNP-3/IP (either TCP or UDP) based
controllers. The DNP-3 standard protocol is an asynchronous
protocol designed to connect directly to computer asynchronous
ports. DNP-3 has been extended to operate over Ethernet using
the IP protocol suite. This gateway converts between the DNP-
3 IP protocol and DNP-3 serial protocols transparently.
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.
Other Features
Dual Serial Ports
The EDNP-3 contains two serial ports. The two serial
ports are independent, and may be used with different
hosts and different serial protocol speeds as well as
different DNP-3 address ranges and timeouts.
Multiple Hosts
The EDNP-3 may communicate with multiple host controllers.
Upgradeable Firmware
Firmware upgrades are downloadable to the gateway. The
utility program required for this, and the actual firmware
upgrades, are available from your dealer. A Windows
95/98/XP/NT workstation is required to run the download
software.
