2.1 Introduction
The structure of a monitoring and control system for electrical substations has a
principle structure as shown in Figure 2. It contains a number of IEDs for the various
purposes.
For performance reasons, do not insert more than 150 IEDs of 650
series type in one PCM600 project. In PCM600 version 2.3, the
maximum number of IEDs is 60. Larger projects can be divided into
several PCM600 projects.
It can be subdivided in the three main parts:
• Bay level IEDs
• Station communication
• Station level IEDs

All three parts require specific engineering and configuration. PCM600 is used to do
the complete engineering and configuration activities needed for bay level IEDs.
