Foreword

GB/T 31230 "Industrial Ethernet fieldbus EtherCAT" is divided into six sections. --- Part 1. General; --- Part 2. Physical layer service and protocol specification; --- Part 3. Data link layer service definition; --- Part 4. Data link layer protocol specification; --- Part 5. Application layer service definition; --- Part 6. Application layer protocol specification. This section GB/T Part of 231,230. This section drafted in accordance with GB/T 1.1-2009 given rules. This part is proposed by China Machinery Industry Federation. This part of the measurement and control of Standardization Technical Committee (SAC/TC124) is administered by the National industrial processes. This section is drafted.

Introduction

This part belongs to the GB/T 31230 series of documents, its purpose is to facilitate the realization of interconnection between the various parts of the automation system. This section Interrelated with other fieldbus standard three-layer reference model, the bus reference model by the IEC /T R61158-1 statements. The main purpose of this section is to provide a set of communication rules, regulations by the peer physical layer entity at the time of execution of communication to express. The physical layer receives data units from the data link layer, encodes them, if necessary, also to increase the communication frame information, the synthesis of the physical channel Number is sent to the transmission medium of a node. Then by another or more other nodes to receive signals, decoding, if necessary, in the data sheet Yuan before being passed to the data link layer of the receiving device also delete information communication frame. General physical layer model shown in Figure 1.

1 Physical Layer Figure generic model

Common characteristics of all variations and types are as follows. --- Digital data transmission; --- Non-isolated (separate) clock transmission; --- Duplex communication (two-way, but at the same time only one direction) or full-duplex communication. EtherCAT cable predetermined medium having the following characteristics. --- Low-voltage differential signal lines (LVDS) transmission rates of up to 100Mbit/s. Industrial Ethernet fieldbus EtherCAT Part 2. Physical layer service and protocol specification

1 Scope

Relations section 1.1 and IEC standards GB/T 31230 in this section depends on the IEC 61158 series of 12 file types in the corresponding section. 1.2 Overview This section defines the part of the demand for fieldbus components, but also provides the necessary media and network configuration to ensure compliance with the following requirements. a) the data integrity of the data link layer error checking before; b) physical layer interoperability between devices. Fieldbus physical layer should be in line with the first layer 7-layer model by GB/T 9387 defined, in addition to frame delimitation of certain types of fieldbus Breaks exist in the physical layer, other type of frame delimiter are present in the data link layer.
