摘要
探讨了RS-232串口与PROFIBUS-DP智能通讯转换节点的设计,重点研究了基于SPC3的实现方案。通过该节点可以很好地解决目前只有RS232串口的现场设备与PROFIBUS-DP总线的挂接问题,其对拓宽PROFIBUS现场总线的应用有着重要的意义。
It is probed for the design of conversing node between RS232 and PROFIBUS-DP, and the primary research is in the scheme of realization based on SPC3. Through this node, the conventional instrumentation only with RS232 interface can communicate with PROFIBUS-DP bus, it has important meanings to widening the application of PROFIBUS.
