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,
读者可以将此两种程序的架构再延伸设计至各种实际应用程序。-Generally used as a PC Based Controller is a field device, which is the main system to accept orders, make a number of operational control. Modbus is a look at the role of Slave, Modbus Master at any time waiting to receive the Query Message, and then to do based on the contents of control, the final results will be controlled in order to return the Response Message. This chapter will be ICP 7524 and ICP 7188E5 equipment design, such as two Modbus RTU, ASCII and Modbus/TCP the Slave application, readers can use this framework for the two procedures designed to further extend the range of practical applications.
