Description: 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.

Description: This server / ModBus slave simulates equipment communicating with the ModBus protocol on a TCP / IP as a controller for example. It responds to requests from a master / client. I used ModScan32 and a monitoring software that I developed in my company for testing.
Some details:
- 4 tables of data are scaled to 200 items each (constant chosen arbitrarily) and values of each item (bit / register) can be modified in the cell corresponding
- Responses to requests functions 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x10, 0x0F
- Return management of exceptions ModBus started but complete
- Visual refresh table data after a write request to complete
The software is not finalized and has been tested only in certain configurations, it must contain some bugs. If you detect inconsistencies vis-à-vis the protocol, please let me know (I have some issues that differ among the PDF and found the software testing as ModScan32).

Description: 不借助其它底层Modbus控件，直接操作底层通讯代码，实现Modbus读写“保持寄存器”数据，支持串口通讯、TCP通讯两种方式。代码只作演示，可做进一步封装，也可稍作修改，用于非标准的Modbus通讯。本代码使用了一个第三方控件SPComm，开发测试环境为Delphi7+Win7，我一直想摆脱Modbus控件(MBAXP Modbus Master ActiveX Control
)，最近自己开发了这个DEMO，分享给大家。(Without other underlying Modbus controls, the direct operation of the underlying communication code, the realization of Modbus read and write, "keep register" data, support for serial communication, TCP communication two ways. The code is for demonstration only, can be further encapsulated, and can be modified slightly for nonstandard Modbus communications. This code uses a third party control SPComm, development test environment for Delphi7+Win7, I always want to get rid of Modbus control (MBAXP Modbus Master ActiveX Control
) recently developed this DEMO and shared it with you.) Platform: |
