The exhibition of ETG Member Meeting 

At the ETG Member Meeting, members from various fields gathered to discuss EtherCAT technology such as IT, energy, and robotics. ETG Members announced development cases applicable to EtherCAT and searched for directions and improvement points for each question. The theme was based on evolving future innovation technologies such as two-arm robots, stage devices, and motion controllers. This year, new technologies and development issues of EtherCAT attracted special attention.

Case Study


[Source] EtherCAT Seminar Reference

  • Presenter : Ahn Hyeonbae(LS Mecapion System Sales, Team Leader)
  • Development Business : Development of collaborative robot joint module
  • Case Study
    • Apply EtherCAT solution for in-line equipment configuration to enable high-speed integrated control from existing PLC control system to PC system
    • Simple all-in-one module design that can be applied to constrained joints of collaborative robots
    • Can be applied variously within 60W~500W category
    • Built-in acceleromete for impact detection detects impact of collaborative robot

  • Presenter : Choi Taeyong(KIMM, Research Engineer)
  • Development Business : Development of EtherCAT based industrial dual-arm robot
  • Case Study
    • In the existing CAN bus, high speed torque control limited by bottleneck. So KIMM applied EtherCAT solution for 80 Byte x 8 nodes, which can be controlled at high speeds
    • Small connectors and cables are required due to space constraints of dual-arm robots
    • 80~100W noise is generated, so the corresponding guideline is required
    • Standardization work required due to difficulty in matching slave and master

  • Presenter : Lim Sun(KETI, Research Engineer)
  • Development Business : Industrial fieldbus-based stage device for simultaneous/synchronous top/bottom device control system.
  • Case Study
    • Developed for the localization of stage devices distributed as foreign equipment
    • As dynamic content is required to meet the trends consumers are demanding, it is necessary to provide stereoscopic content with a colorful stage device instead of a simple stage device
    • The high-speed communication stage device is duplexed using EtherCAT, and synchronous control is enabled
    • One way is to apply TwinCAT which is expensive but requires excellent maintenance,
      A second way to apply low-cost open development method but to maintain it directly. They developed Two Track to suggest the user to choose.

EtherCAT Technology Update

1. EtherCAT P (Power)

  • EtherCAT P is is an addition to the EtherCAT on the cabling level. This technology facilitates the cascading of several EtherCAT devices and therefore only requires one cable to connect and power I/O and field devices. With EtherCAT P, the Us(system and sensor supply) and Up(peripheral voltage for actuators) voltages are directly coupled into the 100 Mbit/s EtherCAT communication line.
  • Benefits
    • Ultra-fast communication and power in one cable
      – US for system and sensors 24V DC/3A
      – UP for peripheral voltage for actuators 24V DC/3A
    • Daisy-chained power supply through EtherCAT P device
    • 100% EtherCAT-compatible : 100 Mbit/s full duplex, processing on the Fly
    • Cascadable in all topologies(star, line, tree)
    • M8, EtherCAT-P Coded

2. Semiconductor TWG

  • Semicondutor TWG is Technical Working Group that Technical Committee (TC) established. It is a specialized system that professionally analyzes technical issues in semiconductor related equipment and provides alternatives. TWG uses a specialized Conformance Test Tool (CTT) to analyze technical issue profiles.
  • Benefits
    • General mechanical error (CDP)
      – Analyze the technology profiles that are commonly encountered in the semiconductor industry.
    • Specific machine error (SDP)
      – Analysis of technical profiles that occur under specific circumstances
    • Firmware Update
      – In the case of firmware update, specify the slave device data under specific circumstances.

3. Mailbox Protocol – AoE

  • AoE (ADS Over EtherCAT) Mailbox Protocol can be particularly useful for slaves with subordinated or cascaded systems, e.g. CANopen gateways. This AoE gateways connects to underlying devices with each supporting their own object dictionaries. It is based on a mailbox protocol with automatic recovery for error messages.
  • Benefits
    • Diagnostics and quick error location verification
      – Analyzes the technology profiles that are commonly encountered in the semiconductor industry
      – Detects faults before they affect the operation of the equipment
    • Working Counter : Monitoring information in datagrams
    • Utilizes standard Ethernet frames to display in plain text
