Network and distribution are the development directions of modern measurement and control system.A distributed measurement and control system based on EtherCAT bus was designed.The system was single master,multi slaves structure.The soft controller TwinCAT was used as master device and a communication and control card was designed as slave device of the measurement and control system.Then EtherCAT communication and multi channel input measurement and output control function of multiple signals were realized.Experimental results show that the system has the characteristics of high precision,good real-time performance and easy expansion.
