“SDO is responsible for telling the drive how to work, while PDO is responsible for keeping the drive working continuously.”—— Essence of understanding from a bald engineer If you have understood SDO, then congratulations, you are just one step away from “making the motor really move” — PDO. PDO is the soul of the entire … Read more
“Whenever you encounter ‘unable to write, unable to read, configuration unsuccessful’, it is mostly an SDO issue.”—— Bald Engineer, years of experience summarized In CANopen, anything related to configuration and parameters is closely tied to SDO: Change mode (0x6060) Change acceleration (0x6083) Configure PDO (0x1600 / 0x1A00) Set heartbeat time (0x1017) Modify node ID (0x2000~) … Read more
View Master Status Obtain the master status and the number of slave device nodes ./ethercat master Example Usage: The master is in idle state, the communication domain is not activated, master data statistics View Slave Information The slaves command is used to view the information of slave device nodes (ESC) mounted on the EtherCAT bus … Read more
Recommended Video In the development of EtherCAT master stations, the bus control logic often relies on a fixed network configuration. Once the position of the slave devices changes, the control logic must be readjusted. Today, we will explore how the ZLG PCle-2E master station card cleverly addresses this issue, enhancing development efficiency. IntroductionFor engineers who … Read more

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
1. Overview of the Porting Process Hardware Platform Setup Selection of the main control chip: It is recommended to use the STM32F4 series (such as STM32F407) or Microchip SAMD5x series, which must support SPI/SQI or HBI interfaces to communicate with LAN9253. Hardware connection: LAN9253 connects to the main control via the SPI interface, requiring configuration … Read more

In the CANopen device model, the primary communication objects are PDO and SDO. So, can they be used simultaneously in a CANopen device? Of course, SDO (Service Data Object) and PDO (Process Data Object) can be used simultaneously. In fact, they serve different purposes in the CANopen network and are often used together to optimize … Read more
