The industrial control and automation sector has invested in the development and standardization of new wireless (WirelessHART, ISA 100.11a, and WIA-PA) and wired (Profibus/Profinet, Modbus, and LonWORK) solutions aimed at automating processes to support standard monitoring and control functions from the perspective of addressing critical applications, as well as those integrated within the Building Internet of Things (BIoT) concept. Distributed data acquisition and control systems allow modern installations to monitor and control devices remotely. Various network protocols have been proposed to specify communication formats between a client/gateway and server devices, with Modbus being an example that has been widely implemented in the latest industrial electrical installations. The main contribution made in this paper concerns the completion of the Modbus Extension (ModbusE) specifications for the server station in the classical Modbus communication architecture, as well as their implementation and testing in an STM32F4 kit. A general-purpose control architecture is proposed for BIoT sector, comprising both intelligent touch switches and communication protocols of which the Modbus protocol is used extensively for the monitoring and control part, especially between clients, smart switches, and devices. The specific contributions concern the presentation of a scientific and practical implementation of improved specifications and their integration as software modules on ModbusE protocol server stations. A client station with a VirtualComm USB PC connection is also implemented in the lab to test the operation of the proposed server with specific Modbus applications.
工业控制与自动化领域已投入开发并标准化新的无线（WirelessHART、ISA 100.11a和WIA-PA）及有线（Profibus/Profinet、Modbus和LonWORK）解决方案，旨在实现流程自动化，从关键应用以及建筑物联网（BIoT）概念中集成的应用角度，支持标准监测和控制功能。分布式数据采集与控制系统使现代装置能够远程监测和控制设备。已提出各种网络协议来指定客户端/网关与服务器设备之间的通信格式，Modbus就是一个在最新工业电气装置中广泛应用的例子。本文的主要贡献在于完成经典Modbus通信架构中服务器站的Modbus扩展（ModbusE）规范，以及在STM32F4套件中对其进行实现和测试。针对BIoT领域提出了一种通用控制架构，包括智能触摸开关和通信协议，其中Modbus协议在监测和控制部分，特别是在客户端、智能开关和设备之间被广泛使用。具体贡献在于展示改进规范的科学实用实现方式，并将其作为软件模块集成到ModbusE协议服务器站。实验室还实现了一个通过VirtualComm USB PC连接的客户端站，以测试所提出的服务器与特定Modbus应用的运行情况。
