PLC IM Curriculum manual
Programmable logic controllers ( PLC ) have become the standards for control tasks in industry. For technicians and engineers, an understanding of the principles & operations of PLC is very important. The proposed PLC training package offers a complete structured solution to the problems of their training. The trainer uses Industry standard PLC with a realistic application board to achieve its objectives. By providing an industry relevant application the system allows user to gain valuable hands on skills in the use of PLC. The system teach-ware provides a structured, selfpaced introduction to the world of PLC’s and their applications.
Topics Covered :
An introduction to relay ladder logic
Programming the controller
Input, Output and Auxiliary relays
Master and Zone control relays, Counters and timers, Sequencers
Using the remote programming software.
The conveyor mechanism is fitted with opto-electronic sensors for detection of components and three pneumatic cylinders with solenoid valves for component selection. The system is pre-wired with start/stop switches and red/green indicators. A three-compartmented bin is provided to receive selected components. Interface units are provided for sensors, motors and solenoid valves. A selection of components for exercises is provided.
Sequence Switch Module – PLC SS
This module provides 8 switch selectable outputs derived from the 24V PLC supply. Inputs to the PLC and outputs from the PLC are simulated with this module.Supply Voltage 110V or 240V AC 50/60Hz.
The system is provided with all suitable hoses and connectors, also user manual, student experiments manual and lecturer’s guide.The trainer comprises of the following:
1 x Conveyor Belt – DC Motor driven
2 x Optoelectronic Sensors
3 x Sping return single action pneumatic pistons.
3 x Pnuematic solinoid valves
3 x Reed relay position switches
On board power supply and interface.
The system is designed to be used with an industrial standard PLC unit or an IBM/PC Simulator System.
The controller unit should be of a type usually used in industrial applications. It should consist of a processor unit and hand-held programmer. The processor unit should have multiple inputs and outputs ( for eg. 10 inputs and 10 output ).
The industrial Controller shall have the following specification.
Inputs : 10-30V DC optically isolated with LED status indicators.
Outputs : Relay contact rated 10-250V AC or 10-125V DC.
Memory : 1200 words with back up. Timers, counters, sequencers, and shift registers: 32
Timers : 0.1 to 999.9s
Counters : 0.1- 9999
Sequencers : 8 bit groups, 100 steps
Shift registers : 8 zone, cascadable.
Internal relays : 150
Supply voltage : 85-132V DC or 170-265V AC 50/60Hz.
Electrically operated compressor – PLC EP
This provides a safe source of compressed air, volume 5 litres at a pressure of 3 bar. The air supply is sufficient for at least 200 cylinder strokes (16mm dia) or 500 cylinder strokes (10mm dia).
Sequence switch module – PLC SS
Based on a pcb mounted on a pvc base, this module provides a switch-selectable output code facility. It is used with a PLC application device for experimentation purposes. It features 8 output lines each of which can be selected as on or off using slide switches, output termination must be via standard screw-clamp terminals.
