1.2 SCADA Gateway Components
1.2.1 SCADA Gateway
The Tait SCADA gateway provides the interface between the SCADA
control system and the DMR network. Its primary function is to control the
transfer of messages from the SCADA control system to SCADA
outstation devices. As it has detailed knowledge of the current network
load, it can queue and prioritize SCADA messages to and from the SCADA
outstation devices, ensuring reliable communications under both normal
and fault conditions.
The SCADA gateway application is normally co-located on the DMR
control node, but can be installed on its own server.
The SCADA gateway supports DNP3 over Ethernet and IEC 60870-5-104
protocols for linking to SCADA control systems.
1.2.2 TD9300 Data Terminals
TD9300 data terminals connect over the DMR network to exchange DMR
control channel and packet data messages with the SCADA gateway. They
forward received messages to their SCADA outstation device (or RTU).
The data terminals support both serial and Ethernet SCADA interfaces to
the SCADA outstation device, including
DNP over TCP/IP, UDP and RS232
IEC 60870-5-101
IEC 60870-5-104
1.3 Tait TN9300 DMR Trunked Network
The Tait TN9300 DMR Trunked network is a wide-area trunked radio
communications network that follows the Digital Mobile Radio open
standard. It
consists of one or more nodes controlling the operation of the
network together with a number of sites, each consisting of several base
stations within a local area network. An IP backbone links the nodes and
sites together.
The base stations provide the RF interface to the mobiles, portables and
Data Terminals that use the network. For more information, see the System
Overview for Tait TN9300 DMR Trunked Networks.
