西门子驱动装置SIMOVERT MicroMaster4具有强大的通讯功能。本文档介绍S7 300C-2DP与驱动装置用PROFIBUS DP协议通讯的基础。
本例中选用S7-300 CPU 314C-2DP作为PROFIBUS-DP主站,连接一个MM420变频器。连接多个MM420时与之相同。 SINAUT MD720-3 有两种不同的操作模式:
终端模式
OPC 模式
设备在这两种模式下的功能范围及工作方式有所不同。在 OPC 模式和终端模式之间进行切换(参见章节“ 激活终端模式” 和“ 激活 OPC 模式” )时必须重新启动机器。
终端模式
SINAUT MD720-3 基于 GSM 网络建立无线数据连接经由 CSD (电路交换数据)通过调制解调器连接,通过发送 SMS(短信息)。
OPC 模式
SINAUT MD720-3 基于 GSM 网络进行无线数据传输通过 S7-200 设备和 OPC 服务器 SINAUT MICRO SC 之间的 GPRS(通用分组无线业务),能够接收到从一台 S7-200 设备发往任意接收站的 SMS。这样通过连接的 PLC 程序模块可以对 SINAUT MD720-3 进行配置,并自动建立S7-200 设备和 OPC 服务器SINAUT MICRO SC 之间基于GPRS 的无线数据连接。
