Maggiori informazioni sul libro

This volume offers a comprehensive collection of automation recipes for technological systems, featuring 16 functional blocks, 8 subroutines, and corresponding graphic pages tailored for monitoring and control within a PLC-HMI-SCADA environment. The PLC code, written in the standard ladder 61131-3 language, ensures portability across different PLC manufacturers. Each control logic is paired with HMI graphic pages for dynamic value display and manual command input. The book is divided into four sections. The first focuses on automation for equipment and sensors, including functional blocks like ElectricMotor for managing electric motor commands and statuses, and sequencers for machinery operation. It also features subroutines for decoupling input/output addresses from internal registers. The second section presents general-purpose recipes, including subroutines for initializing values, grouping SCADA commands, and managing alarm flags, alongside function blocks for generating pulse trains, verifying compliance with thresholds, and real-time linear interpolation. The third section utilizes the PLC’s internal clock for date and time management, with subroutines and function blocks designed for scheduling and managing loads based on time and day. The final section addresses user authentication and authorization, detailing access management for navigation within the operator panel. The book concludes with practical examples of
