About the D400 Applications
The D400 is a SCADA gateway device that encompasses the functionality of several typical
substation devices in one. It can carry out a variety of functions, including:
Data concentration - collect data from intelligent electronic devices (IEDs) installed in
the substation
Data presentation - present collected data to a Supervisory Control and Data
Acquisition (SCADA) system
Digital Event Manager - monitor devices for alarm conditions and issue alarms to the
operator for action
Substation HMI - visually present the substation in one-line diagrams and display
communications data to a system operator to monitor, control and operate the
substation locally, or remotely over a network
Terminal server - provide transparent access (also known as pass-through) to
connected devices using vendor-supplied PC programs
How the D400 works
Figure 54 provides an functional overview of the D400, showing the input and output
through the HMI.
The primary function of the D400 is to concentrate substation data by polling and
receiving information from connected IEDs (Intelligent Electronic Devices). Each device
communicates data to the D400 through a serial or Ethernet network connection using a
selected protocol. The D400 retrieves point information from and sends control requests to
each communicating device.
The D400 can manipulate the data from devices to produce additional local/pseudo data
points. The real data collected from devices and the calculated data are stored in a
database in the D400 and are available to pass on to SCADA master stations and/or HMI
(Human-Machine Interface) applications.
The D400 is able to accomplish these tasks through the use of embedded software
applications. You configure these software applications to set up the D400 to operate as
your system requires.
