Connection and Circuit Technology


PLC is the Short Form of Programmable Logic Controller and is a Microprocessor Based Device.

What is a PLC?


It is a Programmable Memory for Storing Instructions to Implement Specific Functions such as

• Logic

• Sequencing

• Timing

• Counting

• Interlocking to Control Machines and Processors

• More Advanced PLC can also Perform Arithmetic and Data Manipulations

What is a PLC?


PLC were Designed to Eliminate the High Cost and Inflexibility of Relay Control Systems. When they Designed PLCs, they had these Design Criteria:

• Solid-state with Computer Flexibility

• Suited to Industrial Environment

• Easily Programmable

• Easily Maintained

History of the PLC


• Just Relay Replacers• On/Off Control Only• Limited to Repetitive Operations - Transfer

lines, grinding machines, boring machines, etc.

• Improvement Over Relays• Easily Installed• Uses Less Space and Energy• Diagnostic Indicators That Aid

Troubleshooting• Reusable

The Early PLC


• Microprocessor Technology Added Greater Flexibility and Intelligence to PLC

• Capable of Operator Interface, Arithmetic, Data Manipulation and Computer Communications

Early Innovations 1970 - 1974


• Cathode Ray Tube (CRT) Programmer Allowed Relay Symbol Entry

• Arithmetic Function and Improved Instruction Set Allowed Numerical Input Data for Instrumentation Devices

• Logic and Sequencing Tasks Enhanced

Early Innovations 1970 - 1974


• Greater Flexibility with Hardware and Software Enhancements

• Improvements Included:• Larger Memory Capacity• Remote I/O• Analog and Positioning Control• Operator Communications• Software Enhancement• Reduction of Wiring and Installation

Costs

Later Innovations 1975 - 1979


• Early 1980s Microprocessor Technology Brought About Many Advances

• Keen Competition Affected Design

Controllers in the 80‘s


• Hardware Enhancements

• Faster Scan Times

• Small, Low Cost and Reduced Space Requirement

• More I/O Ports

• Direct Connection to Devices

• Improved Mechanical Design

• Peripheral Equipment Improved Operator Interface and System Documentation

Controllers in the 80‘s


• Developments in Hardware

• Advanced Memory

• User Orientated Operator Interface

• Universal Programming Device

• Communication Between Different Brands of PLCs

Todays PLC


• Developments in Software

• IEC 61131-3

• Control Strategies can be Distributed Instead of Centralised

• Integration with other Control Equipment such as Robots

Todays PLC


• I/O Units - Not Directly Connected to One Another

• Programmable - Need Only Change Program when Circuit Condition Changes

• Space Saving - Internal Relays, Timers, Counters, etc.

• Flexibility in Control Changes

• Low Power Consumption

• Easy Debugging
