Overview

Build reliable Modbus based IIoT systems that connect real PLCs, sensors and SCADA to working Python applications. Pulling trustworthy data from Modbus RTU and Modbus TCP devices is harder than it looks. Vendor tables, function codes, RS485 timing, gateways and network security all have to align or your plant ends up with timeouts, bad scaling and frustrated operators. MODBUS FOR IIOT ENGINEERS: BUILD INDUSTRIAL AUTOMATION WITH PYTHON AND RTU/TCP gives you an end to end path from protocol basics to production ready designs. You work with real topologies, from brownfield RS485 segments to Modbus TCP networks, and see how Python fits alongside PLC logic, SCADA, OPC UA, MQTT and cloud platforms. Understand where Modbus sits in practical architectures with PLCs, field devices, SCADA, HMIs, edge gateways and IIoT platforms. Work confidently with coils, discrete inputs, input registers and holding registers, including addressing conventions and vendor specific mapping styles. Use core and advanced Modbus function codes, including diagnostics, mask writes and combined read write operations on real devices. Design and troubleshoot Modbus RTU on RS485, from unit loads and termination to biasing, CRC errors and realistic bus throughput. Apply Modbus TCP with MBAP headers and connection management to build clean IP networks for PLCs, SCADA servers and edge devices. Install and use PyModbus and MinimalModbus to build synchronous and asynchronous clients, as well as TCP and RTU servers for simulation and testing. Create robust tag models in Python with correct types, signed values, floats, byte order, scaling factors and engineering units. Drive configuration with JSON and YAML so devices, tags and polling rules can be updated without touching code. Use Modbus simulators, Wireshark and protocol analyzers, plus Python based test harnesses and regression suites, to validate buses, gateways and devices. Integrate Modbus data into SQL and time series databases, dashboards and SCADA historians using Python edge collectors. Build Modbus to MQTT and HTTP gateways, and see how Modbus feeds higher level stacks that use OPC UA, MQTT and cloud services. Work through complete projects such as an RTU sensor logger, a Modbus TCP driven process simulator with a simple HMI, and a Modbus data pipeline into a web dashboard. The book includes practical commissioning checklists, reference tables and field proven patterns that help you verify addressing, buses, devices and failover behaviour before you sign off a system. Throughout the book you get extensive, ready to adapt Python, JSON and YAML code that you can plug into your own PLCs, meters, drives, I O modules, gateways and IIoT platforms to build real projects, not just isolated demos.
