Softing epgate Pb series Gateway - integrates the Profibus bus into the ethernet/ip network

One background

PROFIBUS It is a mature fieldbus technology , It is mainly used in process automation industry , For example, metal smelting 、 Petrochemical and food industries . because PROFIBUS The bus has some unique performance advantages , For example, a stable installation method 、 Special physical transmission technology, etc , So it is still widely used in process automation system .

In recent years , With the increasing demand of industrial equipment interconnection and industrial Internet of things , Industrial Ethernet is also developing rapidly . and EtherNet/IP It has many advantages , Like a high degree of flexibility 、 Excellent interoperability, etc , Therefore, it can occupy a place in industrial Ethernet for a long time . According to recent reports ,EtherNet/IP By percentage 17% Market share and PROFINET And ranked first in the industrial network market .

The inherent property limitation of traditional bus system makes it impossible to be directly integrated into industrial Ethernet system , But with industry 4.0 And the development of industrial Internet of things , We need to integrate fieldbus into industrial Ethernet system , In order to make full use of the advantages brought by industrial Ethernet technology and Fieldbus transmission technology .

Two Solution

Use Softing epGate PB Series gateway , Users can PROFIBUS The bus is directly integrated into EtherNet/IP In the network , At the same time, it can be omitted in the field scheme design DP/PA coupler , Lower deployment costs . Besides ,epGate PB The series gateway supports configuration by using standard industry tools 、 Parameterization and plant asset management . The series has the following four models ：

| take PROFIBUS Network segments are directly integrated into EtherNet/IP In the network

epGate PB The series gateway is in EtherNet/IP Act as EtherNet/IP equipment （Adapter）; stay PROFIBUS Act as in the network segment PROFIBUS PA and PROFIBUS DP master station , Thus, the PROFIBUS The slave station is directly integrated into EtherNet/IP In the control system .epGate PB The series gateway supports common EtherNet/IP Control system and its corresponding programming tools , Such as Rockwell Control Logix（Studio 5000）、Modicon M580（EcoStruxure Control Expert） and Emerson DeltaV（AMS Device Manager）.

Besides , because epGate PB The series gateway also supports EtherNet/IP DLR（Device Level Ring）, Therefore, this series of gateways can be used in EtherNet/IP Redundant communication in the ring network , The controller and the device are connected through a ring topology , It not only ensures the reliability of the system , Moreover, the loss caused by shutdown due to line failure is avoided .

| Use standardized tools for plant asset management

In the context of process automation , Manage the assets of field equipment through the management system , It can effectively reduce costs and improve plant performance .epGate PB Series gateways provide standardized tools , It can be used for equipment parametric configuration and asset management , Include SIMATIC PDM and FDT/DTM. By using epGate PB The series gateway can be connected from Ethernet to PROFIBUS The Internet , combining SIMATIC PDM Application or FDT/DTM The framework shall be used to configure the field equipment 、 Parameterization and troubleshooting and maintenance , Thus, the asset management of the factory is realized .

| Simple deployment 、 Easy to configure

By using epGate PB Series gateway , Users no longer need to install PROFIBUS DP/PA coupler , Or modify the site layout , Can be PROFIBUS PA The network segment is directly integrated into the Ethernet , In order to reuse the existing PROFIBUS Network segment .

from PROFIBUS Mapping to EtherNet/IP It's very simple , No additional configuration software is required , Just in WEB In the interface PROFIBUS All of the segments GSD File consolidation and export as a EDS file . This file contains all... In the network segment PROFIBUS Function block of the device , Thus, the user can use this file in a familiar programming tool to configure the gateway , There is no need to learn more about PROFIBUS knowledge .

（PROFIBUS Mapping to EtherNet/IP）

in the light of Rockwell PLC,epGate PB The series gateway supports exporting Add-On Instruction（AOI）.AOI yes Rockwell A new function of programming software , It allows users to develop and package in customized instructions PLC Code , And these instructions can be reused throughout the program . Derived AOI Contains detailed POFIBUS Data type definition , And the user can reuse these instructions , This simplifies programming , And improved efficiency .

3、 ... and summary

adopt epGate PB Series gateway , Can be PROFIBUS The bus is directly integrated into EtherNet/IP Industrial Ethernet . Give Way PROFIBUS Bus and EtherNet/IP Industrial Ethernet is an organic combination of the two , It gives full play to the respective advantages of fieldbus and industrial Ethernet ......
