Viewing data
The real-time database (RTDB) acts as a central container for all data that is collected and
may need to be exchanged between D400 applications. The real-time database stores the
value of all input/output data collected by the D400 in the form of point data, as well as the
occurrence of events that take place (for example, disturbance or fault records). The D400
can manipulate the data from devices to produce additional local/pseudo data points. The
real-time database is commonly referred to as the system point database.
The following general types of information are stored:
Point data and values
Analog set point status
Digital control status
Tagging/Inhibit status
•Force value status
•Statistics
