Short Content: Introduction The industrial control moved toward the centralized monitor, the collection and distribution control from the single plane control, now entered the network intensive manufacture time. Industry controller Lian Wang has also provided for the network management conveniently. Modbus is in the industry controller's network protocol one kind. The Modbus agreement is applies on the electronic controller's one kind of communication protocol. Through this agreement, the controller, the controller (e.g. ethernet) and between other equipment may correspond by way ...

Short Content: 1 introduction Serial communication's widespread application may cause each kind of transmission facility organically to be united as one body, can carry on the data exchange and the information transmission reliably safely. But because on each equipment transmission channel's signal is different, applies the serial port are also various, must complete the numerous equipment correspondences, inevitably must involve to each equipment's between serial port transformation question. In order to cause computer's RS-232 connection to carry on the correspondence with each ...
