A PLC contains an operating system that allows for downloading and executing user programs, communicating with I/O modules and other PLCs, and holding configuration data. A PLC retains its operating system, user programs, and some data in retentive memory even when power is removed. A PLC executes programs through a repeated scan cycle of input, program execution, and output steps. During input scan, data is collected from input modules and stored in an input image area. During program execution, the input image is used and the program is run to update the output image area. During output scan, data in the output image area is sent to output modules.

The CPU executes user programs to control inputs and outputs based on a scan cycle. The PLC also includes memory to store programs and input/output data, as well as a power supply to provide power to the electronic components. Programming devices are used to create and transfer logic programs to the PLC memory.
Industrial automation involves using computers and programmable controllers to control manufacturing processes. This increases productivity, quality and safety while reducing costs. Automation uses sensors to collect input data, transmitters to convert it to electrical signals, and control systems like PLCs, DCSs and PID controllers to process the signals. Output devices like actuators then control machines based on the electronic instructions. PLCs in particular have replaced mechanical relays and are now widely used in industrial control applications across various industries. They allow flexible programming to monitor processes and adjust operations as needed.
The document discusses different types of control systems for CPUs, including hardwired and microprogrammed control. It explains that microprogrammed control uses sequences of microinstructions stored in memory to interpret instructions, allowing for more flexibility than hardwired control. The execute cycle is categorized into four groups of actions: CPU-memory transfers, CPU-I/O transfers, data processing, and control alterations. Microinstructions are organized into fields that activate control signals, and the main concerns in microinstruction sequencing design are microinstruction size and address generation time.
The document discusses programmable logic controllers (PLCs), including their architecture, types, modules, configuration, scan cycle, capabilities, and selection criteria. It describes the main components of a PLC, including input and output modules, a central processing unit, memory, power supply, and programming devices. The three main types of PLC architectures are fixed, modular, and distributed PLCs, which vary in size, flexibility, customization, and suitable applications.
The document provides an introduction to programmable logic controllers (PLCs) for industrial automation. It discusses PLC hardware components including the CPU, power supply, memory, and I/O modules. It describes the logical rack configuration and addressing schemes for discrete and analog I/O points. The document also covers common I/O connection modes like sinking and sourcing. Programming methods like ladder logic, function block diagrams, and statement lists are introduced. Finally, the selection of PLCs for different industrial automation needs is briefly addressed.
1. The document discusses microprocessors, microcontrollers, and Programmable Logic Controllers (PLCs). It describes the basic components and functions of microprocessors, including the arithmetic logic unit (ALU) and control unit.
2. PLCs are described as industrial microcontroller systems used to control electro-mechanical devices. The key components of a PLC include an input module, processor, programming device, and output module.

Ch 3 PLCs and Processing I/O 1
Chapter 3 PLCs and Processing I/O
Introduction
After an introduction of PLCs in chapter one, various characteristics of the PLC need to be
discussed. The purpose now is to discuss what parts constitute a modern PLC and how these
parts interface. The topology of a PLC system is also discussed as to how PLCs are distributed
in a manufacturing environment to best control a process efficiently.
Since each is electronic and operates using one or more microprocessors, a 5 volt power supply
and CPU (central processing unit) are the core of the PLC. Included in the CPU is a computer
with memory and communications hardware to communicate to a programming panel, the I/O,
and to a network which is either peer-to-peer or a multimode network.
Many PLC vendors divide the work of the PLC between multiple microprocessors with
coordination handled by a master microprocessor. One processor may be assigned to handle the
I/O. Another may handle the networking and communication to the pro ...

Decolonizing Universal Design for LearningFrederic Fovet
UDL has gained in popularity over the last decade both in the K-12 and the post-secondary sectors. The usefulness of UDL to create inclusive learning experiences for the full array of diverse learners has been well documented in the literature, and there is now increasing scholarship examining the process of integrating UDL strategically across organisations. One concern, however, remains under-reported and under-researched. Much of the scholarship on UDL ironically remains while and Eurocentric. Even if UDL, as a discourse, considers the decolonization of the curriculum, it is abundantly clear that the research and advocacy related to UDL originates almost exclusively from the Global North and from a Euro-Caucasian authorship. It is argued that it is high time for the way UDL has been monopolized by Global North scholars and practitioners to be challenged. Voices discussing and framing UDL, from the Global South and Indigenous communities, must be amplified and showcased in order to rectify this glaring imbalance and contradiction.
This session represents an opportunity for the author to reflect on a volume he has just finished editing entitled Decolonizing UDL and to highlight and share insights into the key innovations, promising practices, and calls for change, originating from the Global South and Indigenous Communities, that have woven the canvas of this book. The session seeks to create a space for critical dialogue, for the challenging of existing power dynamics within the UDL scholarship, and for the emergence of transformative voices from underrepresented communities. The workshop will use the UDL principles scrupulously to engage participants in diverse ways (challenging single story approaches to the narrative that surrounds UDL implementation) , as well as offer multiple means of action and expression for them to gain ownership over the key themes and concerns of the session (by encouraging a broad range of interventions, contributions, and stances).

Programmable Logic
Controllers
PLC Basics
Dr. D. J. Jackson Lecture 2-2Electrical & Computer Engineering
Operating systems and application
programs
• A PLC contains a basic operating system that
allows for:
– Downloading and executing user (ladder logic)
programs
– Communicating with devices
• I/O modules
• Other PLCs on a network
– Holding configuration data such as
• Number and type of I/O modules present in the PLC
system
• Status information
2. 2-2
Dr. D. J. Jackson Lecture 2-3Electrical & Computer Engineering
Operating systems and application
programs
• A PLC retains its operating system, user
programs, and some data in retentive
(nonvolatile) memory
– While the PLC is off or is even disconnected from
the power supply (given a battery backup)
• A PLC can then resume running a user
program as soon as power is restored
– The PLC may be programmed to require some
operator action before resuming user program
execution (for safety purposes)
Dr. D. J. Jackson Lecture 2-4Electrical & Computer Engineering
User program execution
• A PLC executes an initialization step when placed in
run mode, then repeatedly executes a scan cycle
sequence
• The basic PLC scan cycle consists of three steps
– An input scan
– A user program scan
– An output scan
• The total time for one complete program scan is a
function of processor speed, I/O modules used, and
length of user program
• Typically, hundreds of complete scans can take place
in 1 second
3. 2-3
Dr. D. J. Jackson Lecture 2-5Electrical & Computer Engineering
Input scan
• During the input scan, data is taken from all input
modules in the system and placed into an area of
PLC memory referred to as the input image area
InputmoduleInputmodule

Input Image Area
Dr. D. J. Jackson Lecture 2-6Electrical & Computer Engineering
User program scan
• During the program scan, data in the input image
area is applied to the user program, the user
program is executed and the output image area is
updated

• During the output scan, data is taken from
the output image area and sent to all
output modules in the system
OutputmoduleOutputmodule
PLC
Output Image Area
Dr. D. J. Jackson Lecture 2-8Electrical & Computer Engineering
PLC scanning considerations
• During the input scan, input terminals are
read and the input image area is updated
accordingly.
• During the program scan
– data in the input image area is applied to the user
program
– the program is executed (instructions carried out
in sequence)
– the output image area is updated appropriately
• During the output scan, data associated with
the output image area is transferred to
output terminals
5. 2-5
Dr. D. J. Jackson Lecture 2-9Electrical & Computer Engineering
PLC scanning considerations
• It is important to understand that the input,
program, and output scans are separate,
independent functions
– Any changes in the status of input devices during
the program or output scan are not recognized
until the next input scan
• Furthermore, data changes in the output
table are not transferred to the output
terminals during the input and program scans
• The transfer affecting the output devices
takes place only during the output scan
Dr. D. J. Jackson Lecture 2-10Electrical & Computer Engineering
PLC scanning considerations
• With all PLCs, there are special processing
considerations to note
• First, all PLCs take a specific amount of time
to scan their operational programs
completely
• Typically, the program scanning takes place
left to right across each rung and from the
top to bottom rungs, in order
• Usually, the complete ladder scan time is a
few milliseconds
6. 2-6
Dr. D. J. Jackson Lecture 2-11Electrical & Computer Engineering
PLC scanning considerations
• Another scanning consideration involves
proper operational sequencing of events
• An output might not go on immediately in
sequence as it would in a relay logic system
• In a relay logic system, an event occurring
anywhere in the ladder control system results
in immediate action
• In a PLC ladder control diagram, however, no
effect takes place until the rung is scanned
• In most cases, the PLC logic delay effect is
inconsequential
Dr. D. J. Jackson Lecture 2-12Electrical & Computer Engineering
PLC scanning considerations
• Program (ladder logic) scanning typically takes place
left to right across each rung and from the top to
bottom rungs, in order
– Known as rung scanning, it is the method used, for example,
by Allen-Bradley
• Another method, used by Modicon/Schneider
Automation is known as column scanning
– Here the processor "looks" at the first contact at the top left
corner and reads the first column from top to bottom
– It next reads the second column from top to bottom, and so
on
• Either method, rung or column, is appropriate.
