Hongke will share the EtherCAT demo for you and teach you how to quickly transition from other protocols to EtherCAT industrial bus

EtherCAT It's a high performance 、 Low cost deterministic Ethernet Technology , The processing method of Ethernet data frames by its nodes can improve the bandwidth utilization , One data frame per cycle is enough to refresh the data of the whole system , No switches or hubs , So as to ensure real-time .

EtherCAT It is a protocol widely used in industry , Hongke has many years of technical experience in the field of fieldbus and industrial Ethernet , stay EtherCAT aspect , Hongke provides EtherCAT Master slave source code 、EtherCAT Configuration and diagnostic tools 、EtherCAT IO modular , And for EtherCAT A board that interconnects with other protocols 、 Gateway and other hardware equipment .

Next , This article will introduce Hongke EtherCAT The solution is as follows demo Performance shown in , So as to help you deploy quickly EtherCAT technology .

This demo It includes a master unit and a slave station , This host unit is based on I7 The processor IPC unit , Including real-time operating system INtime And proprietary software protocol stack Hongke EtherCAT Master. Besides , It also includes a support EtherCAT and Modbus Protocol programmable logic controller 、 Six from Korean manufacturers Crevis Of I/O Device and one for EtherCAT and CAN Protocol gateway .

The demo Controlled by peripheral devices , The total size of these peripheral devices sent to the network is 800 Bytes of analog and digital data , This can include 300 Analog signals and 1600 Digital signals . For some industries with large enough controlled objects , Such as energy 、 chemical 、 Oil refining, etc , Such performance is very common .

All the data collected by the device are combined into a command or data message , And transfer from one device to another in turn . After starting the device at the same time , The necessary information is transmitted and stored in the corresponding register of the data message . such , Conflict can be avoided , Make the most efficient use of the channels that transmit data , Realize the high speed of industrial cycle .

EtherCAT The bus has up to 100 Megabytes of bandwidth . This in Hongke EtherCAT demo in , We did 500 Microsecond stable cycle time , Channel utilization is 13% within . In Hongke EtherCAT With the help of gateway , Can be based on EtherCAT Industrial networks of protocols and other systems running on such protocols , Such as CANopen、Profibus、Profinet、Modbus And so on .

This configuration can be used as a transition from other protocols to EtherCAT The middle option , And let you optimize the cost of purchasing equipment . stay EtherCAT Master With the help of the , You can get all the necessary analysis data , So as to determine the Correlation .
