The device description file of the slave completely describes the parameters that can and cannot be changed in the device. Each parameter includes at least the following attributes: Index Number — Used to uniquely identify all parameters. The index number consists of a “main index” and a “subindex” to group and arrange related parameters. Main … Read more
To get straight to the point, whether other servo drives can receive commands from the PLC (master) depends on the network topology and configuration that allow for continued communication. Here is a detailed analysis of this issue: 1. How EtherCAT Networks Work EtherCAT is a real-time industrial fieldbus protocol based on Ethernet, utilizing a “Processing … Read more
The CoE object “Restore default parameters” (子索引 01) can be used to restore all modifiable CoE objects in the ELxxxx terminal to factory default values (see the image below). Therefore, please carefully confirm whether this operation is necessary before proceeding. Double-click SubIndex 01 to enter the settings dialog. Enter the reset value 1684107116 in the … Read more
The EtherCAT Processing Unit (EPU) is the logical core of the EtherCAT slave controller, containing registers, memory, and a data processing unit. Any frame must first pass through Port A before entering the EPU. The EPU is responsible for receiving, parsing, and processing the entire EtherCAT data stream. Cable redundancy requires a second network card. … Read more
In software, the following image is often seen, where some information can help quickly understand the EtherCAT configuration status.Among them, the “Cmd” column displays the types of EtherCAT commands. Cmd Abbreviation Name Description 0 NOP No Operation A slave ignores the command. 1 APRD Auto Increment Read A slave increments the address. A slave writes … Read more
The EtherCAT State Machine (ESM) coordinates the master and slave applications during startup and operation. The state changes of slave devices are usually initiated by requests from the master; however, in some cases, the local applications of the slave can also independently change states. To transition from the Initialization state to the Operational state, EtherCAT … Read more
The upper interface in the image displays the address, name, and state machine status of the slave device.The “CRC” column shows the cyclic redundancy check counter value of a single EtherCAT slave device at a certain moment. The cyclic redundancy check counters for ports A, B (if used), C (if used), and D (if used) … Read more
Summarizing practical experiences in work and sharing discussions in social circles, creating the most grounded public account. In a default configuration of an EtherCAT network, the slave devices cannot be plugged or unplugged at will while running, as this may lead to serious consequences. According to the EtherCAT transmission mechanism, the master station identifies slave … Read more
Click the blue words to follow us Overview This article introduces the method for configuring communication between Beckhoff PLC as an EtherCAT slave and Inovance PLC as an EtherCAT master. Beckhoff Hardware: CX8010 Inovance Hardware: AC802 Get related materials and software in the comments section. 01 Hardware Connection Method Connect the EtherCAT port of the … Read more
