Once the engineering of the protection relay is finished, the results must be written to
the protection relay. Conversely some parts of the engineering information can be read
from the protection relay for various purposes.
The connection between the physical IED and PCM600 is established via an Ethernet
link on the front or rear port on the protection relay.

Monitoring and control system structure
The monitoring and control system for electrical substations contains a number of
devices for various purposes.
See PCM600 documentation for the recommended size of a project.
Larger projects can be divided into several PCM600 projects.

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 devices
•
Station communication
•
Station level devices
All three parts require specific engineering and configuration. PCM600 is used to do
the complete engineering and configuration activities needed for bay level devices.
Product type and version specific engineering data needed by PCM600 for protection,
control and communication engineering of a particular bay device is given in a
protection relay connectivity package.
