Title
Recommended Practice for Data Communications between Remote Terminal Units and Intelligent Electronic Devices in a Substation

The Institute of Electrical and Electronics Engineers, Inc.

Publication Date:
Sep 21, 2000

Scope:

This recommended practice presents a uniform set of guidelines for communications and interoperation of IEDs and remote terminal units (RTUs) in an electric utility substation. This recommended practice does not establish an underlying communication standard. Instead, it provides a specific limited subset of two existing communication protocols, to encourage understanding and timely application.

Purpose

The purpose of this standard is to illustrate a recommended practice that will eliminate the need for timeconsuming and costly efforts by implementers to interface their equipment to other equipment on a project-by-project basis. It is assumed that implementers understand the basic concepts of RTU and IED communications, as well as the overall concept of the supervisory control and data acquisition (SCADA) system and its master station.

Two different protocols with many similarities are included in this recommended practice. Each is intended to satisfy the communication requirements between RTU-to-IED communications and also contain an adequate framework for most system applications. Both protocols are fully specified and cross-referenced so that users and developers can choose one or the other, based on the system or product application requirements.
