欢迎使用“PLC串口通信调试” 本软件主要用于PLC(或单片机)与计算机的串口通信调试。软件根据目前PLC常用的多种串行通信协议的特点设计，数据的输入、组织和显示方式灵活多样，便于使用和观察调试。 在编制计算机与PLC的串口通信程序时，由于计算机和可编程设备双方均需编制通信程序，调试时往往不知道是哪一方的程序出了问题。可以使用本软件调试PLC一侧的程序，调试正确后再调试计算机侧的程序。本软件为PLC串口通信程序的调试提供了便利。-Welcome to "PLC serial communications debugging" This software mainly used for PLC (or single-chip) and the computer s serial communication debugging. According to the current PLC software for a variety of common characteristics of serial communication protocol design, data input, organize, and display flexible, easy-to-use debugging and observation. In the preparation of the computer s serial communication with the PLC program, computers and programmable devices as a result of both procedures require the preparation of communication, debugging often do not know which side the procedure is a problem. Can use the software side of the PLC program debugging, testing the right side after the debugging of computer procedures. The software for the PLC seria
