摘要
设计分析了在工业现场应用领域,频率变送器的应用现状,提出了一种基于CAN总线频率变送安全栅的设计思路,将本质安全、CAN总线、频率变送器结合到一起,解决了现场应用需增加关联设备的应用问题,能通过CAN总线接入现场总线控制系统,并能兼容传统的DCS系统。
The design analysis the applications of the frenquency transmitter in the industrial field. It propose a new idea about frenquency transmitter which is based on CAN Bus.The design Integrate the intrinsical safe,CAN bus and frenquency transmitter together. The frequency transmitter can access to FCS via Can bus,also can access to the traditional DCS via 4~20mA.
