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
Driven by the wave of digitalization, data transmission protocols are undergoing unprecedented transformations. Today, we focus on a significant innovation within the MCP (Model Context Protocol) — Streamable HTTP. This new protocol not only simplifies the traditional HTTP+SSE transmission method but also opens up new pathways for data interaction with features such as stateless server … Read more
Abstract: The pulse generator is widely used in power electronics, motion control, vehicle control, and other applications. It is a fundamental and versatile component for device driving and control. However, the current pulse generator has weak network communication capabilities, which cannot meet high-speed control demands and is difficult to integrate into intelligent manufacturing systems. To … Read more
