Description: Modbus协议最初由Modicon公司开发出来，在1979年末该公司成为施耐德自动化(Schneider Automation)部门的一部分，现在Modbus已经是工业领域全球最流行的协议。此协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备，包括PLC，DCS，智能仪表等都在使用Modbus协议作为他们之间的通讯标准。有了它，不同厂商生产的控制设备可以连成工业网络，进行集中监控。-Modicon Modbus protocol originally developed by the out at the end of 1979 it became the Schneider Automation (Schneider Automation) department as part of Modbus is now the world' s most popular industrial protocol. The protocol supports a traditional RS-232, RS-422, RS-485 and Ethernet devices. Many industrial equipment, including PLC, DCS, intelligent instruments and so on using the Modbus protocol as standard for communication between them. With it, different manufacturers of industrial control equipment can be connected into the network, centralized control.

Description: MAX485资料The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E,
and MAX1487E are low-power transceivers for RS-485 and
RS-422 communications in harsh environments. Each driver
output and receiver input is protected against ±15kV electro-
static discharge (ESD) shocks, without latchup. These parts
contain one driver and one receiver. -The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E,

Description: A universal asynchronous receiver/transmitter, abbreviated UART ( /ˈ juː ɑrt/), is a type of "asynchronous receiver/transmitter", a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly used in conjunction with communication standards such as EIA RS-232, RS-422 or RS-485. The universal designation indicates that the data format and transmission speeds are configurable and that the actual electric signaling levels and methods (such as differential signaling etc.) typically are handled by a special driver circuit external to the UART.

Description: RS485协议，在工业控制等环境中，常会有电气噪声干扰传输线路，使用RS-232 通讯时经常
因外界的电气干扰而导致信号传输错误；另外，RS-232 通讯的最大传输距离在不增加缓冲
器的情况下只可以达到15 米。为了解决上述问题，RS-485/422 通讯方式就应运而生了。-RS485 protocol, in the industrial control environment, often have a transmission line of electrical noise interference, the use of RS-232 communication often
