摘要
本文从现场通信角度出发，阐述了通用现场通信控制器的概念，并着重论述了组态式多协议现场通信控制装置的设计思想，以及该装置的软硬件构成和工作原理，最后给出了现场通信实例，验证了该装置的组态可行性和灵活性。
Neuron Chip has 11 programmable I/O pins(IO0- - IO10) . They have 34 selectable modes of operation.For example:bit I/O ;byte I/O ;asynchronous serial I/O ;parallel I/O . this mode of asynchronous serial I/O can only operate at half- duplex mode. the paper introduce a kind of LON node which can realizing full- duplex asynchronous serial communication between serial I/O device and Neuron Chip.
