Abstract: PROFIBUS technique is applied to the control system of SFC high-frequency transmitter successfully. The control system is effective and flexible by using the distributed I/O mode ,the application of PLC and the programming with STEP7.According to the application of PROFIBUS technique, the difficulty of the maintenance of the system is reduced and the period of empoldering is shorten.
