1785-CHBM

详细内容：1785-CHBM 用户界面 每台PLC都通过CPU模块上的MPI集中编程接口和配置有MPI接口的PC机相连。我们采用西门子的CP5611与PLC的CPU相连。PC机中配置SIMATICSTEP7V5.2编程软件。 由于是冗余系统，还需要安装西门子的冗余软件，才能做到PLC的两个CPU之间同步。3台上位机中，其中两台是操作员用的监控机，另一台为维修机。在整个系统中，上位机之间可以互相通讯，也可以与PLC之间通讯。每台PC机都要安装CP5611驱动软件，才能完成功能。 程序结构 系统组态及参数设置 由SIMATICSTEP7V5.2编程软件，进入硬件组态状态，对各台PLC进行网络参数设置。首先，建立Pro2ject，如取名为C：\ swjtu，在该文件下选择网络Subnet为PROFIBUS，站名为SIMATIC414HStation，然后进行硬件组态。其次是建立各站在网络的地址。最后组态3个PG/PC站，在选项窗口中选中CP5611，并分配地址，主编程站地址为0，其余两个只要地址不相同即可。 程序结构 西门子SIMATICS7-400HPLC的编程器STEP7可运行在PC机的Windows环境下，界面友好，提供了梯形图、语句表和块图3种形式的编程、调试、诊断等功能。本实例采用模块化程序结构，程序由几大功能块组成，每个功能块完成一系列的控制逻辑，放置在组织块OB1中的指令决定控制程序的各功能块的执行。本例中功能块FC1是微机联锁命令处理程序，FC2是进路处理程序，FC3，FC4是微机联锁状态处理程序，FC5是常量定义，FC6是信号输出处理，FC7是道岔输出处理，FC8是信号采集。程序结构框图如图4所示。功能块为多层次调用，FC1在调用其他功能块，比如FC1调用FC9， FC9调用FC10，FC10调用FC11、FC12、FC13、FC14等。在STEP7中，允许功能块调用最多为16层。 　　图3为应用于唐山钢铁集团公司焦化厂火车站的微机联锁系统的PROFIBUS-DP/MPI网络原理框图。3台监控机为监控层，PLC为联锁层，I /O为控制层。车站联锁系统主要由联锁以及信号、道岔、区段和进路的动作建立。本例中，以车站微机联锁的控制过程说明PROFIBUS-DP网络的实践应用。 网络系统结构图 图3　网络系统结构图 　　进路控制过程包括进路建立、进路解锁。进路建立包括进路选择、道岔控制、进路锁闭、信号控制，进路解锁就是对已建立的进路、道岔进行的进路锁闭，进路解锁包括取消进路、人工解锁、正常解锁、中途折返解锁、故障解锁。 程序结构框图 图4　程序结构框图 　　在组织块OB1中，先调用FC1对联锁命令进行处理，其中包括进路处理、道岔处理、信号处理，调用FC2对进路进行处理，调用功能块FC1、 FC2对联锁状态进行处理，再调用功能块FC6、FC7、FC8对数据进行输入输出处理。以功能块FC1命令处理程序为例，说明其功能调用过程。功能块 FC1先调用 FC10进行进路选择，然后调用FC11、FC12、FC13等，对其他命令进行处理。 结论 从实际应用来看，整个网络运行良好，网络结构简单，技术性能稳定。实践证明，PROFIBUS-DP网构成的灵活实用分布式网络在铁路系统有良好的应用前景。 140XTS10215 1,768.42 1 PC RMB 140XTS10206 1,386.83 1 PC RMB 140XTS01212 2,147.64
