The connection between the physical IED and PCM600 is established via an Ethernet
link on the front or rear port on the IED.
2.1 Monitoring and control system structure
The monitoring and control system for electrical substations contains a number of
IEDs for various purposes.
See PCM600 documentation for the recommended size of a project.
Larger projects can be divided into several PCM600 projects.

Figure 2: Principle structure of a monitoring and control system for a substation
The monitoring and control system can be divided into three main parts.
• Bay level IEDs
• Station communication
• Station level IEDs
All three parts require specific engineering and configuration.
The plant structure is used to identify each IED in its location within the substation
organization. Plant structure is a logical image of the substation and the bays within the
substation. The organization structure for the IEDs may differ from the structure of the
primary equipment in the substation.
