In practice, we summarize and share discussions in our circle, making the most grounded public account. Beckhoff users extensively use EtherCAT, and generally do not need to have a deep understanding of EtherCAT because most projects only require automatic scanning and default settings. However, when communication errors occur and troubleshooting is needed, engineers must understand … Read more

In the field environment of Profibus, we use a variety of systems, and the devices we face interference from are diverse, so the sources of interference are also varied. Many failures caused by interference are more difficult to troubleshoot than other faults. Before troubleshooting interference failures, we need to understand the types of interference. In … Read more
In the field environment of Profibus, the systems we use are diverse, and the devices we are interfered with are varied, so the sources of interference are also peculiar. Many failures caused by interference are more difficult to troubleshoot than other failures. Before eliminating interference faults, we need to understand the types of interference. To … Read more

1. Basic Properties of PROFIBUS PROFIBUS specifies the technical and functional characteristics of the serial fieldbus system. Through this system, distributed, digital field programmable controllers can be networked from the lower level (sensor, actuator level) to the middle level (unit level). PROFIBUS is divided into master and slave stations. > Master Station The master station … Read more
