scope:

This document defines a recommended practice for the design, testing, and operation of communications networks within, to, and from electric power substations. Security considerations are included in the above. It does not establish a new underlying communications standard. Instead, this document presents guidelines and best practices for designing these communication networks.

Purpose

This recommended practice provides direction for implementers who wish to produce interoperable and secure communications for an electric power substation network. It also provides direction for users, system integrators, and equipment manufacturers who need to establish requirements and design of communications networks within, to, and from the electric power substation. This is meant to address both the physical and logical elements of the network.
