环网介质冗余MRP调试
环网介质冗余MRP调试方法很多，可以直接查看CP443-1通讯模块或IM154-3PN模块的状态指示灯；也可以在线查看CP443-1模块诊断缓冲区（Diagnostic Buffer）信息；还可以利用PROFINET IO WEB功能在远程实现诊断维护。
（1）如果环网域中某一节点断开，则对应的域管理器CP443-1模块上的桔黄色MAINT指示灯常亮。如果断点在IM154-3PN分布式I/O模块，则P1或P2端口上的黄色LINK指示灯将熄灭。
如果断点在SCALANCE交换机，则端口对应的桔黄色指示灯熄灭。由于X208是网管型交换机，具有环网冗余管理功能（RM），因此交换机上桔黄色L指示灯熄灭，而F指示灯亮红。
（2）CP443-1模块作为PROFINET通讯控制器，其诊断缓冲区（Diagnostic Buffer）能给出详尽的通讯网络故障诊断信息。例如“Ring opened”、“No physical connection on port”或“Ring closed again”等提示信息。
（3）还可以直接针对PROFINET网络进行在线诊断。如果环网域中某一节点断开，则在线诊断状态（Status）显示为一个黄色扳手图标，提示信息为“Maintenance demanded”。
（4）除了以上几种网络诊断方式外，还可利用PROFINET IO WEB功能，利用Internet Explorer浏览器查看更为详尽的诊断状态信息，实现远程诊断维护。另外操作维护人员还可利用OS站监控画面直接查看诊断信息。
应用体会
PROFINET通讯介于PROFIBUS和Ethernet两个通讯协议之间取长补短，采用TCP/IP和ISO协议，既具有PROFIBUS通讯的稳定性和实时性，又具有Ethernet通讯的广泛使用性和兼容性。
相比PROFIBUS通讯并针对自身项目特点，高效低成本的实施了设备自动调试（Automatic Commissioning）、环网介质冗余（MRP）、IO WEB等网络功能。特别是IO WEB功能，大大方便了操作维护人员实现远程诊断维护；expansibility and convenient operation. It is suitable for frequent startup and harsh environment. Therefore, PLC is usually used as the core of electric control system in three-dimensional parking garage control system. As the bottom layer of the network, fieldbus technology shows great advantages in the design, installation, operation and maintenance of the control system with its simple structure. Therefore, PROFIBUS FMS and PROFIBUS DP are used to form a two-layer control network in this paper. PROFIBUS FMS mainly completes the cyclic and non cyclic communication tasks with medium transmission speed. It is usually used for the mutual communication between PLC and PC and between PLC and PLC. The underlying network chooses PROFIBUS DP, which is mainly because PROFIBUS DP is an optimized high-speed communication connection, which is used for the communication between equipment level decentralized I / O and constitutes a single master station system to obtain the shortest overall cycle time.
