Zhang Zhi-xiu · Industrial Instrumentation & Automation · 2007
Based on the bus technology of Profibus-DP,one kind of the reservoir gate monitoring and control system is developed.The system is consisted of the PLC of S7-300 series as the core.In this system the position of the gate's displacement is measured by a rotating coder which provides a Profibus-DP interface,and the reliability is enhanced.The communication program is listed.
