基于上位机与S120直接通讯的自动化系统

摘要

SINAMICS S120 is introduced by Siemens company,which combines V/f control,vector control and servo control in one drive control solutions. Due to high performance and good flexibility ,it has widespread application value of drive. In order to simplify the S120 control system,one scheme which based on PC and S120 direct communication was proposed. It changed the original three layer structures PC ,PLC and S120 to two layers structures PC and S120. It presented in detail about the PC and S120 direct communication hardware and software requirements and configuration process with one specific example.%SINAMICS S120是西门子公司推出的集V/f、矢量控制及伺服控制于一体的驱动控制解决方案,由于其性能高和灵活性好,因此具有广泛的传动应用价值.为了简化S120的控制系统,提出了基于上位机与SINAMICS S120直接通讯的方案,将原有的上位机、PLC和S120的3层结构简化为上位机、S120的2层结构,并结合具体实例详细介绍了上位机与西门子S120直接通讯的软硬件需求和配置过程.
