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 document discusses programmable logic controller instructions for bit shifting, sequencing, and loading. It provides details on:
- Bit shift instructions like bit shift left (BSL) and bit shift right (BSR) that allow basic shift operations on bit arrays
- Sequencer instructions like sequencer output (SQO), sequencer compare (SQC), and sequencer load (SQL) that are useful for outputting, comparing or loading a sequence of data on a recurring basis
- Parameters, status bits, and usage of these instructions including addressing bit arrays, controlling sequence position and length, comparing input to references, and loading data into sequence files.
This document discusses Programmable Logic Controllers (PLCs), including PLC addressing, basic instructions like examine if closed (XIC) and output energize (OTE), and using a PLC simulator. It explains how inputs and outputs are mapped to data files and addresses. Basic PLC programming concepts are introduced like branches and parallel logic. The document recommends using the simulator's built-in simulations, like the batch simulator, to design and test ladder logic programs.
This document discusses basic ladder logic programming concepts for programmable logic controllers (PLCs). It covers Boolean logic and ladder logic equivalents like logical AND, OR, and NOT. Common ladder logic sequences like start-stop-seal circuits and basic interlocks are described. The document provides examples of ladder logic diagrams and emphasizes the importance of properly formatting outputs and ladder logic rungs for readability and clarity.
This document discusses programmable logic controller (PLC) counter functions. It begins with objectives of describing PLC counter functions, listing major counting functions, and applying counters and timers to process control. It then introduces PLC counters and their programming formats. The document focuses on up counters (CTU) and down counters (CTD), providing examples and explanations of how they work. It describes counter status bits and how they function. Finally, it provides examples of counter applications, including straight counting, timing a process after reaching a count, and delayed start of counting.
The document discusses programming concepts for Unitronics PLCs using VisiLogic software. It describes creating ladder logic programs with contacts, coils and functions to control automation processes. It also covers creating human-machine interfaces (HMIs) with displays, variables and editors to allow operators to monitor and interact with the PLC program. The VisiLogic software is used to write, debug and download PLC and HMI applications to the controller.

This document contains lecture slides about comparison and math instructions used in programmable logic controllers (PLCs). It discusses various comparison instructions like equal, not equal, less than, greater than, and masked comparisons. It also covers math instructions for addition, subtraction, multiplication, and division. Finally, it describes how the arithmetic status bits in the PLC are updated after instructions are executed to indicate conditions like carry, overflow, zero, and sign.
The document discusses various program control flow instructions used in programmable logic controllers (PLCs), including:
- Jump (JMP) and Label (LBL) instructions allow skipping portions of ladder logic to optimize scan time or create loops.
- Jump to Subroutine (JSR), Subroutine (SBR) and Return (RET) instructions allow executing reusable code blocks called subroutines.
- Master Control Reset (MCR) instructions create zones that reset non-retentive outputs when inactive, reducing scan time.
- Temporary End (TND) and Suspend (SUS) instructions halt or pause ladder logic execution for debugging purposes.
The document discusses setting up programmable logic controllers (PLCs) to communicate over Ethernet using message (MSG) instructions. It explains that two data files need to be created: 1) a MESSAGE data file to hold information for MSG instructions, and 2) a ROUTING INFORMATION data file to hold routing data from MSG instructions. It provides an example program where one PLC writes data from its input file to the output file of a second PLC using a MSG instruction. It outlines the steps to configure the MSG instruction and shows how the routing information is populated in the data file.
This document contains a series of lectures about programmable logic controllers and interrupts. It discusses what an interrupt is, when controller operation can be interrupted, interrupt priorities, interrupt latency, and interrupt instructions like INT, UID, UIE, and UIF. Interrupts allow a controller to suspend its normal execution, service an event, and then resume where it left off. They are prioritized and can only be serviced at certain points in the scan cycle.
