Introduction

The purpose of this document is to describe the specific implementation of the IEC 60870-
5-104 Source Code Library, V3.
Uses the Triangle MicroWorks, Inc. IEC 60870-5-104 Slave Source Code Library Version 3.
This document and the documents listed below provide complete information on how to
communicate via the IEC 60870-5-104 protocol.
• IEC 60870-5-104 = Companion standard for IEC 60870-5-101 over TCP/IP
• IEC 60870-5-101 = Companion standard for basic telecontrol tasks
• IEC 60870-5-101 A2 = Addendum 2 for IEC 60870-5-101
• IEC 60870-5-5 = Basic Application Functions
• IEC 60870-5-4 = Definition and Coding of Application Information Elements
• IEC 60870-5-3 = General Structure of Application Data

Interoperability

This companion standard presents sets of parameters and alternatives from which subsets
must be selected to implement telecontrol systems. Certain parameter values, such as the
choice of structured or unstructured fields of the
represent mutually exclusive alternatives. This means that only one value of the defined
parameters is admitted per system. Other parameters, such as the listed set of different
process information in command and in monitor direction allow the specification of the
complete set or subsets, as appropriate for given applications. This clause summarizes the
parameters of the previous clauses to facilitate a suitable selection for a specific application.
If a system is composed of equipment stemming from different manufacturers, it is
necessary that all partners agree on the selected parameters.
The interoperability list is defined as in IEC 60870-5-101 and extended with parameters used
in this standard. The text descriptions of parameters which are not applicable to this
companion standard are struck-through (corresponding check box is marked black).
