This document describes the hardware structure and configuration of ET200M as a distributed DP slave, as well as the implementation of features such as module hot-plugging and functioning as a redundant slave. It mainly involves the configuration of active bus backplane and soft redundancy functionality.
The guide provides an overview of the ET200M active backplane, describing its role in PROFIBUS DP distributed I/O systems and the supported hardware configuration. It outlines the soft‑redundancy functions, including CPU continuity, IO value retention, and diagnostic signaling.
Detailed sections list the compatible module part numbers, maximum installation limits, wiring and mounting instructions, and the properties of each module type. Support URLs and reference documents are included for further assistance. This manual is written in Chinese.
