PURPOSE AND SCOPE

The protocol standard documents IEC 60870-5-1 to IEC 60870-5-6 and companion standard IEC 60870-5-101 define the requirements of the communications protocol.

This document describes the address and configuration requirements of the IEC 60870-5-101 protocol for a slave station application, this is generally a National Grid Substation Automation System (SAS). These address and configuration requirements are essential for the correct working of the SAS to the National Grid UK Transmission iEMS SCADA system, which are outside the scope of the above documents.

Whilst the IEC 60870 series of standards define the technical requirements of the communications protocol, they do not address how to use the protocol in a target SAS. This document describes the detailed addressing requirements for the National Grid specific application of the IEC 60870-5-101 protocol.
