Pulse generator with real-time industrial ethernet

Abstract

The pulse generator is the basic equipment for device drivers and control, widely used in many occasions, such as power electronics, motion control, vehicle control, etc. However, the used pulse generator is weak in communication, which cannot meet high-speed control requirements or be used in the intelligent manufacturing application. To solve the above problem, this paper designed a pulse generator with real-time industrial ethernet EtherCAT and Loongson processor LS1C. The designed pulse generators can form the daisy chain and ring topology by EtherCAT. And the pulse generator is very flexible and suited for many different applications with its four operation modes. Finally, experiment results are presented to demonstrate the operation modes and performance.
