一般使用PC Based Controller 都是当作现场设备的一种,也就是要接受
主系统的命令,做一些操作控制。以Modbus 来看属于Slave 的角色,随
时等待接收Modbus Master 的Query Message,然后依据内容做控制,最后
将控制结果以Response Message 回传。本章将以ICP 7524 及ICP 7188E5 等
两种设备分别设计Modbus RTU、ASCII 及Modbus/TCP 的Slave 应用程序,
读者可以将此两种

Modbus 通信規約基本上是遵循Master and Slave 的通信步驟,有一方扮演Master 角色採取主動詢問方式,送出Query Message 給Slave 方,然後由Slave 方依據接到的Query Message 內容準備Response Message 回傳給Master。即使目前硬體通信已經可以達到雙方互相主動通信的能力,但是於Modbus 通信規約的規定,必須一方為Master,另一方為Slave 不能互換角色。一般使用上,監控系統(HMI)都為Master,PLC、電
