CHAPTER 9: ABOUT THE D400 APPLICATIONS
Figure 54: D400 HMI overview
Types of applications
The D400 makes use of three types of embedded software applications to collect, present
and manipulate data. These are called client, server and automation applications
respectively. The input and output data of these applications is stored in a real-time
database, commonly referred to as the System Point Database.
Client application
This type of application typically interfaces with a substation device over a
communications channel, and collects data points from it. The client application writes
input point values to the real-time database and may process control requests. Known
previously within GE embedded devices as a Data Collection Application (DCA).
