Abstract: Based on FPGA and ieee1588PTPv2 protocol, HL-2M timing control system is designed to 
provide trigger for the measurement and control system at precise time. The client/server dual-mode management 
is applied in the data acquisition system. In HL-2M first plasma discharge experiment, the test results showed that 
the time sequence control and acquisition system had the characteristics of nanosecond precision level trigger, 
strong real-time performance, fast data transmission speed, stable and reliable, convenient deployment and 
management. The timing control and data acquisition systems meet the application requirements of HL-2M first 
plasma discharge experiment.
