869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE

Introduction

The 869 Motor Protection, Control and Management System is a microprocessor-based
unit intended for the management and primary protection of medium and large sized
motors. Base relay models provide thermal overload and overcurrent protection plus a
number of current and voltage based backup functions.
The 869 has a two-stage communications capability. The base CPU supports Modbus
protocol through the Ethernet, USB, serial and WiFi port. In addition, the base CPU also
supports IEC 103, DNP serial, and TFTP protocol. Once the communications module option
is added to the base, the base Ethernet port becomes disabled but the two Ethernet ports
on the communications module have enhanced communications capabilities such as
IEC61850, IEC62439 parallel redundancy protocol and IEEE 1588 Precision Time Protocol.
The communications CPU also supports Modbus TCP, IEC 104, DNP TCP, TFTP, SFTP, and
SNTP protocol.
