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。-Modbus agreement at first by Modicon company developed, and in late 1979 the company become snyder Automation (Schneider Automation) part of the department, now Modbus is already the world s most popular industrial fields of the agreement. This agreement support traditional RS-232, RS-422, RS-485 and Ethernet equipment. Many industrial equipment, including PLC, DCS, intelligent instruments are using Modbus agreement as they of the communication between a standard. With it, different manufacturer that control equipment can industrial network repeatedly, centralized monitoring.

Description: The SuperCom Serial Communication Library is a programer s library used to develop serial communication applications.The functions are grouped logically with respect to their functionality and portability. Some of the SuperCom API
functions are specific to seriel communications (RS-232, RS-422/485, TAPI, Modem), but nearly all of them are
platform independent thus also available in ISDN and TCP/IP. This enables developing of portable applications without
extra effort and costs.
