There are also additional functions for managing projects and organizing user rights.
•
PCM600 user management
•
Organizing users regarding their rights, profiles and passwords to use
different tools and functions in the tools.
•
Defining allowed activities for user profiles to use tools in PCM600.
Once the engineering of the protection relay is finished, the results must be written to
the protection relay.
The connection between the physical IED and PCM600 is established via an Ethernet
link on the front or rear port on the protection relay.
2.1
Monitoring and control system structure
The monitoring and control system for electrical substations contains a number of
devices for various purposes.
The maximum size of a project is 180 devices. However, in order to
maintain good performance and usability of the tool, it is
recommended to divide one big project into multiple smaller PCM600
projects.
