Guide to Selecting Fieldbuses: Which is Better, Profibus, Modbus, or EtherCAT? Hello everyone, I am Xiao Feng. Yesterday, I received a call from a junior colleague who said he had a new project and needed to choose a fieldbus. He asked me, “Xiao Feng, with so many fieldbuses available, which one should I choose? Is … Read more
In today’s and future intelligent distribution centers, flexible topology, automatic addressing, and inherent network security are justsome of the advantages of EtherCAT. Internal logistics is a stronghold for EtherCAT: in any other industry, the unique selling points of this technology have almost no such advantage. Due to its unique operating principle, EtherCAT offers many special … Read more
1. High Hardware Investment Threshold The implementation of this technology requires dedicated hardware support, which is a significant departure from conventional Ethernet protocols. Unlike Ethernet/IP or Modbus TCP solutions that utilize general network devices, EtherCAT systems require slave devices to integrate dedicated communication chips (such as Beckhoff’s ET series control chips) or be equipped with … 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
“PLC Device Coordination: Cross-System Collaboration Solutions, Boosting Production Efficiency by 80%, Boss Calls It Professional!” Have you ever been driven crazy by the “information islands” on the production line? Guess what? Yesterday, Old Zhang’s food factory had another fryer explosion—the PLC of the packaging line was outputting wildly, while the PLC of the filling line … Read more

After introducing the content related to OPC UA communication, we have basically covered the main communication buses and protocols related to industrial automation. So, why have we focused on communication for nearly two years? Of course, for PLC/PAC engineers, or for electrical engineers or automation engineers, the core is not just communication; there are also … Read more
The power supply products with built-in EtherCAT communication capabilities facilitate transparent power and system monitoring. Beckhoff’s PS 2000 series has launched a new model with an integrated EtherCAT interface, further enhancing the existing three PS series power supply products. They can easily collect more measurement and device data, achieving comprehensive system monitoring to improve equipment … Read more
With the rapid development of renewable energy generation, smart grids, and distributed energy systems, the importance of Energy Storage Systems (ESS) is becoming increasingly prominent. ESS requires high-precision, real-time, and reliable communication technologies to support its complex operational demands. The industrial EtherCAT (Ethernet for Control Automation Technology) bus, with its unique advantages, is becoming an … Read more
