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: 100 java实现modbus 从站、主站-This project represents a Modbus implementation in 100 Java. It can be used to implement Modbus masters and slaves in various flavors:
Serial:
ASCII, RTU (Master only), BIN
IP:
TCP,UDP
The design of this library is fully object oriented, based on abstractions which should support easy understanding, reusability and extensibility.

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: Modbus TCP common driver class. This class implements a modbus TCP master driver. It supports the following commands: Read coils Read discrete inputs Write single coil Write multiple cooils Read holding register Read input register Write single register Write multiple register All commands can be sent in synchronous or asynchronous mode. If a value is accessed in synchronous mode the program will stop and wait for slave to response. If the slave didn t answer within a specified time a timeout exception is called. The class uses multi threading for both synchronous and asynchronous access. For the communication two lines are created. This is necessary because the synchronous thread has to wait for a previous command to finish. Platform: |

Description: Modbus -communication protocol is based on the master-slave architecture. It uses RS-485, RS-422, RS-232 interfaces, as well as Ethernet TCP / IP networks (Modbus TCP protocol) for data transfer.
The Modbus RTU message consists of the address of the SlaveID device, the function code, the special data, depending on the function code and the CRC of the checksum.
