In the automotive welding workshop, the operation screen suddenly displayed a “D840.3” communication alarm, indicating that the data interruption of equipment utilization rate between the PLC and the MES system has lasted for 23 minutes. At this time, although the production line is still running, the lack of quality traceability information will result in the … Read more
5. LwIP Memory Management 1. What is Memory Management? (1) Memory management refers to the techniques used for the allocation and utilization of computer memory resources during software execution. Its main purpose is to efficiently and quickly allocate memory and to release and reclaim memory resources at appropriate times (similar to the malloc and free … Read more
LwIP protocol stack supports various network interfaces (network cards). Since network cards interact directly with the hardware platform, the handling differs based on the hardware. How does LwIP accommodate these different network cards? LwIP provides a unified interface, while the underlying functions need to be implemented by the user, such as initializing the network card, … 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
