{"product_id":"b0h56zyhv6","title":"Understanding Modbus: A Practical Guide to the Protocol, with Hands-On Microcomputer Examples","description":"\u003cp\u003eThe quiet workhorse of industrial communication—finally explained. Modbus is everywhere. Four decades after it was invented, it still connects the meters, drives, sensors, controllers, and SCADA systems that run modern industry—and sooner or later, anyone working with industrial or embedded systems has to deal with it. Most references describe the protocol and stop there.  This book does something better: it teaches you how Modbus actually works, and then proves it by making it run in front of you.\u003c\/p\u003e\n\n\u003cp\u003eStarting from a single bit and building all the way to a working monitoring-and-control application,  Understanding Modbus  walks through the data model, the message frame byte by byte, every common function code, and all three transports— RTU  and  ASCII  on serial lines, and  Modbus TCP  over Ethernet. Then it puts an inexpensive microcomputer on your desk and turns the theory into running  Python : you'll write clients and servers, talk to real serial devices over  RS-485 , decode signed and floating-point values, build a complete control project, troubleshoot faults with a clear method, secure your deployment, and see exactly where Modbus fits among PLCs, SCADA, gateways, and the newer protocols layered above it.\u003c\/p\u003e\n\n\u003cp\u003eWhat you'll learn The four-table data model—and the addressing that trips up every newcomer The Modbus frame, byte by byte, across serial and Ethernet Every common function code, plus exceptions and diagnostics Hands-on clients and servers in Python with pymodbus Modbus RTU over real RS-485 wiring, start to finish Decoding 32-bit integers and IEEE floats—and the word-order trap A complete, working monitoring-and-control project A repeatable method for troubleshooting any Modbus fault Performance, polling strategy, and security in the real world How Modbus works alongside PLCs, SCADA, and modern protocols Fully illustrated , with hands-on examples, end-of-chapter exercises, and quick-reference appendices—function codes, exception codes, a pymodbus quick reference, wiring notes, and a glossary—you'll return to for years.\u003c\/p\u003e\n\n\u003cp\u003eWhether you're an  automation technician , an  embedded or IoT developer , a  maker , or an  engineer  who keeps running into Modbus and wants to finally master it, this is the practical, ground-up guide that rewards the time.\u003c\/p\u003e\n\n\u003cp\u003eGet the book.
