Programmable logic controllers (PLCs) have been used extensively and are offered in terms of functions program memories and the number of inputs/outputs (I/Os) ranging from a few to thousands. With a focus on how to design and implement a PLC this volume explains hardware and associated basic concepts of PLC. Authors have used PIC16F1847 microcontroller with: 8192 words of Flash program memory 1024 bytes of SRAM data memory 256 bytes of EEPROM data memory the maximum operating speed of 32 MHz 16-level deep hardware stack an enhanced instruction set consisting of 49 single-word instructions. Flowcharts are provided to help the understanding of macros (instructions). Aimed at researchers and graduate students in electrical engineering power electronics robotics and automation sensors this book: Explains how to design and use a PIC16F1847 microcontroller-based PLC. Provides easy to use software structures written by using the PIC Assembly programming language. Describes a PLC from a designer's perspective. Explains the basic hardware and basic software structures of the PIC16F1847 based PLC. Focuses on concepts like Contact and Relay Based Macros Flip-Flop Macros Timer Macros Counter Macros and Comparison Macros. . Language: English
