HART智能仪表在国内发展较为迅速,目前HART协议主要用在仪表的调试、校准、日常维护等,把HART仪表组成网络与PLC进行通信,从而直接并入控制系统还不多见.文中对此进行了研究,并在某个化工车间复剂生产系统中将两者相结合,实现了S7-224XP通过自由口协议与HAILT适配器进行通信,以及ADAM-5510M控制器通过串口与HART适配器进行通信,组成控制系统.系统在实际生产中运行稳定,以较低的成本实现了防爆区域的自动控制,具有一定的推广价值.%The communication between HART bus and PLC control system is rare. This paper designs a control system being a combination of PLC and HART bus. The system is used in a Chemical workshop. In this control system S7224XP uses the free ports protocol to communicate with HART adapter and ADAM-5510M uses the serial communication ports to communicate with HART adapter. The control system can be used in explosion-proof area and the cost is very low. The integration of HART bus and PLC will be worthy of using abroad.
