目前,PROFIBUS已成为欧洲销售量占第一位的现场总线,可编程序控制器和现场总线器件日益得益于标准化的优点,若采用有PROFIBUS接口的现场总线器件,大多数Siemens公司的自动化部件均有PROFIBUS总线接口,CP541通讯处理器是连接到PROFIBUS的桥。针对安全的通讯系统经过SINEC L1相当于SIMATIC S5总线系统低档性能范围。用于两种故障安全的可编程序控制器S5—95F和S5—115F。SIMATIC通讯接口已由德国技术监督局和德国贸易事故保险会认证,并作为无反应和针对安全的原型试验,新的CP541没有
Currently, PROFIBUS has become the number-one fieldbus in Europe, with PLCs and fieldbus devices increasingly benefitting from the benefits of standardization. With fieldbus devices with a PROFIBUS interface, most of Siemens Automation’s components Have PROFIBUS interface, CP541 communication processor is connected to PROFIBUS bridge. The SINEC L1-compliant communication system is equivalent to the low-end performance range of the SIMATIC S5 bus system. Programmable controller for both fail-safe S5-95F and S5-115F. The SIMATIC communication interface has been certified by the German Technical Directorate and the German Trade accident insurance and as a non-reactive and safety-oriented prototype test, the new CP541 has no
