摘要：神光Ⅲ工程的激光参数测量系统电控工程设计要求网络通信能力强，且系统可靠性高,而西门子PLC具有可靠性高、功能强大、使用方便、编程简单、抗干扰强等优点，在工业控制领域得到了广泛应用。采用西门子S7200 PLC的两路脉冲输出控制2台步进电机，S7300 PLC作为总的处理器处理多个S7200的信息，同时与工业以太网之间采用PROFIBUS进行现场总线通信，实现了西门子PLC对大量步进电机的控制和与主控系统进行高效率通信的功能。在实验的基础上验证了该方案的可行性，并且它可以降低现场设备连接的工作量和费用，保证系统的可靠性。

Abstract: Shenguang Ⅲ laser measurement system electric control engineering design required good communication and reliability, and Siemens PLC with high reliability, powerful, easy to use and simple programming, and good antiinterference in the field of industrial control has been widely applied. S7200 who could output two pulse was used to control two stepper motors. S7300 was used as the processor to handle the information of many S7200s. On the other hand, S7300 communicated with Ethernet based on PROFIBUS. In this way, the control of Siemens PLC to a large number of steppermotors and communication with main control system on highefficiency were realized. The feasibility of the was verified based on experiment, reduces the field devices connected to workload and costs, and ensures the reliability of the system.
