红瘦子(红模拟)的博文大全：开发技术汇合（蕴含Qt实用技术、树莓派、三维、OpenCV、OpenGL、ffmpeg、OSG、单片机、软硬联合等等）继续更新中...（点击传送门）
单干案例专栏：案例分享（体验Demo可下载，只定制）
前言
西门子PLC、台达PLC、法兰克机床等等多年以前玩得比拟多，有tcp/ip通信也有modbus通信，modbus又分为网络，485，232等。
医疗我的项目，焊接机器人我的项目，工控机床我的项目，数控我的项目，物联网我的项目用的挺多的，将要害的通信技术抽离进去，独自弄成工具。
需要
与各种其余行业仪器通信软件开发的通信外围模块，modbus功能模块，制作成调试工具，可满足个别状况的调试。
1.反对通过串口232,485端口进行通信；
2.反对设置关上端口的参数；
3.反对写入bool，int，dInt，real，dReal参数类型数据；
4.反对读取bool，int，dInt，real，dReal参数类型数据；
5.减少10种主题格调切换（仅用于预抉择主题格调）；
