PIC16F1847 Microcontroller-Based Programmable Logic Controller [PDF ebook] 
Advanced Concepts

The PIC16F1847-Based PLC project supports up to 4 analog inputs and 1 analog output, 1 High Speed Counter, 2 PWM (pulse width modulation) outputs, 1 Drum Sequencer Instruction with up to 16 steps, the implementation of Sequential Function Charts (SFCs) with up to 24 steps. This volume presents advanced concepts of the PIC16F1847-Based PLC project and consists of topics like program control, high speed counter and PWM macros. It further explains memory related drum sequencer instruction, sequential functional charts, and analog input and output modules. Aimed at researchers and graduate students in electrical engineering, power electronics, robotics and automation, sensors, this book:

Presents program control macros to enable or disable a block of PLC program or to move execution of a program from one place to another.

Proposes a High-Speed Counter and four PWM Macros for high speed counting and PWM operations.

Develops memory related macros to enable the user to do memory read/write operations.

Provides a Drum Sequencer instruction with up to 16 steps and 16 outputs on each step.

Discusses the implementation of Sequential Function Chart (SFC) elements with up to 24 steps.
