The core difference among SNMP, Modbus, and CAN lies in their completely different design goals: SNMP is designed specifically for network device management (such as routers and servers), Modbus focuses on industrial device data exchange (such as PLCs and sensors), and CAN is aimed at real-time cont Read More

The core difference between Modbus protocol and CAN protocol lies in their design positioning: Modbus is an application layer protocol for industrial equipment data exchange, relying on underlying buses such as RS485 and TCP; CAN is a bottom layer (physical+data link layer) protocol that balances da Read More

Transformers, often regarded as the backbone of modern electrical systems, play a crucial role in efficiently transmitting and distributing electricity. By converting alternating current (AC) voltage levels, transformers ensure that power can be safely and effectively used across various application Read More
