红胖子(红模仿)的博文大全：开发技术集合（包含Qt实用技术、树莓派、三维、OpenCV、OpenGL、ffmpeg、OSG、单片机、软硬结合等等）持续更新中…（点击传送门）
合作案例专栏：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较多，有tcp/ip通讯也有modbus通讯，modbus又分为网络，485，232等。
医疗项目，焊接机器人项目，工控机床项目，数控项目，物联网项目用的挺多的，将关键的通信技术抽离出来，单独弄成工具。
需求
与各种其他行业仪器通讯软件开发的通讯核心模块，modbus功能模块，制作成调试工具，可满足一般情况的调试。
1.支持通过串口232,485端口进行通讯；
2.支持设置打开端口的参数；
3.支持写入bool，int，dInt，real，dReal参数类型数据；
4.支持读取bool，int，dInt，real，dReal参数类型数据；
5.增加10种主题风格切换（仅用于预选择主题风格）；
