注:S7-200SMART的TSAP支持03.00或是03.01.
(4)程序设计:
通信程序只需要在1200PLC处编写,S7-200SMARTPLC处*编写任何通信程序,这里我们以把S7-1200PLC中DB1.DBB0的数据写入到S7-200SMART的VB0中,以读取S7-200SMART系列PLC中的VB1的数据放到S7-1200PLC的DB1.DBB1中为例,说明程序的设计。
在1200PLC中同样添加一个DB块,在DB块的属性中取消优化块的访问功能,在DB块里面建立两个变量,分别命名为”send_data”以及”recev_data”。数据类型为Byte,需要把send_data的数据发到的S7-200SMART的VB0中,把从S7-200SMART的VB1中的数据读取过来放到 recev_data的变量中。如下图所示:
然后从右侧的通信指令中的S7通信中拖拽PUT和GET指令到OB1编写通信程序,调用PUT/GET指令时,系统会自动调试需要分配一个背景DB ,指令调用完后,填写相应的地址。如下图所示:
注:CPU会自动的把S7-200SMART系列PLC的整个V区默认为数据块DB1,所以访问VB0,的地址为DB.DBB0。
注:M0.5为CPU属性中设置的系统时钟存储器,频率为1HZ,如下图所示:
(5)测试
把做好的程序,分别下载到PLC中,然后使用监控表和状态图表进行测试,如下图所示:
大家还有关于S7通信的相关问题和经验,可以留言与我们分享。
