It uses a programmable memory to store instructions and carry out functions to control machines and processes. The PLC performs the logic functions of relays, timers, counters and sequencers. It has the following advantages: The PLC (Programmable Logic Controller) is largely divided into the basic commands, function commands and exclusive commands, and ample command types are available. The commands can be used according to the purpose and application such as the PLC … Chapter 3 - Fundamental PLC Programming Chapter 4 - Advanced Programming Techniques Chapter 5 - Mnemonic Programming Code Chapter 6 - Wiring Techniques Chapter 7 - Analog I/O Chapter 8 - Discrete Position Sensors Chapter 9 - Encoders, Transducers, and Advanced Sensors Chapter 10 - Closed Loop and PID Control Chapter 11 - Motor Controls The PLC in automation technology 1.1 Introduction The first Programmable Logic Controller (PLC) was developed by a group of engineers at General Motors in 1968, when the company were looking for an alternative to replace complex relay control systems. The new control system had to meet the following requirements: Simple programming Lecture – Introduction to PLC's MME 486 – Fall 2006 3 of 47. The First Programmable Logic Controllers (PLCs) • Introduced in the late 1960’s • Developed to offer the same functionality as the existing relay logic systems • Programmable, reusable and reliable.

The PLC in automation technology 1.1 Introduction The first Programmable Logic Controller (PLC) was developed by a group of engineers at General Motors in 1968, when the company were looking for an alternative to replace complex relay control systems. The new control system had to meet the following requirements: Simple programming

The commands can be used according to the purpose and application such as the PLC support function used when supporting the user PLCs. Inputs Address Device Name Device Type Description INPUT1 PB1 pushbutton switch Reset System INPUT2 PB2 pushbutton switch Start System INPUT3 PB3 pushbutton switch Stop System INPUT4 SS4 selector switch System in Auto Mode INPUT5 CR1 relay Emergency Stop Cleared INPUT6 PB6 pushbutton switch Start Press INPUT7 PB7 pushbutton switch Stop Press INPUT10 PB10 pushbutton switch Raise Spindle INPUT11 PB11 pushbutton switch Lower Spindle INPUT12 PB12 pushbutton switch Hold Part In Place INPUT20 PLC programming is a logical procedure In a PLC program, “things” (inputs and rungs) are either TRUE or FALSE If the proper input conditions are TRUE: The rung becomes TRUE and an output action occurs (for example, a motor turns on) If the proper input conditions are not TRUE: The rung becomes FALSE and an output action does not occur Chapter 3 - Fundamental PLC Programming Chapter 4 - Advanced Programming Techniques Chapter 5 - Mnemonic Programming Code Chapter 6 - Wiring Techniques Chapter 7 - Analog I/O Chapter 8 - Discrete Position Sensors Chapter 9 - Encoders, Transducers, and Advanced Sensors Chapter 10 - Closed Loop and PID Control Chapter 11 - Motor Controls Lecture – Introduction to PLC's MME 486 – Fall 2006 3 of 47. The First Programmable Logic Controllers (PLCs) • Introduced in the late 1960’s • Developed to offer the same functionality as the existing relay logic systems • Programmable, reusable and reliable. (PLC Memory) Ladder Logic Program Runs Output Image (PLC Memory) State of Actual Output Device As the ladder logic program is scanned, it reads the input data table then writes to a portion of PLC memory - the output data, table as it executes The output data table is copied to the actual output devices after the ladder logic has been scanned. The book will therefore be interested to everyone who works with, or wants to learn about programming PLCs, no matter which PLC brand they use. The ebook consists of 15 chapters: + 1 About PLCs + 2 Digital Signals and Digital Inputs and Outputs + 3 Analog Signals and Analog I/O + 4 Structured Design + 5 Introduction to Programming and IEC 61131-3 of PLC programming, timers, counters, program control instructions, data manipulation instructions, math instructions, sequencer and shift register instructions, PLC installation, editing and troubleshooting.

Lecture – Introduction to PLC's MME 486 – Fall 2006 35 of 47 Entering And Running The PLC Program To enter the program into the PLC, place the processor in the PROGRAM mode and enter the instructions one-by-one using the programming device To operate the program, the controller is placed in the RUN mode, or operating cycle instructions based on program instructions in memory. Output modules convert control instructions from the CPU into a digital or analog signal that can be used to control various field devices (actuators).
