Module Content
Outline Syllabus:
Understand the design and operational characteristics of a PLC system. Design characteristics: unitary; modular; rack-mounted.Input and output devices: mechanical switches; non-mechanical digital sources; transducers; relays. Internal architecture: central processor unit (CPU); arithmetic logic unit (ALU); storage devices; memory; opto-isolators; input and output units; flags; shift; registers. Operational characteristics: scanning; performing logic operations; continuous updating; mass input/output (I/O) copying.
Be able to apply ladder programme to solve engineering problems. Logic functions: writing programmes using logic functions based on relay ladder logic (AND; OR; EXCLUSIVE OR; NAND; NOR). Write programs: use of ladder and logic diagrams; statement lists; Boolean algebra; function diagrams; graphical programming languages; production of a PLC. Advanced functions: less than; greater than; binary to BCD conversion; proportional feedback control. Producing and storing text: contact labels; rung labels; programming lists; cross-referencing’s and debug programs: forcing inputs, forcing outputs; changing data; comparing files (tapes, EPROM, disc); displayed error analysis. Associated elements: contacts; coils; timers; counters; override facilities; flip-flops; shift registers; sequencers.
Be able to read and interpret pneumatic and hydraulic fluid power diagrams.Pneumatic and hydraulic symbols: read and interpret eg energy conversion, valve, energy transmission, control and miscellaneous symbols; use of appropriate British and International. Standards eg ISO 1219-2 (2009), ISO 9461 (Hydraulics), ISO 5599 (Pneumatics). Pneumatic and hydraulic equipment: types, construction, function and operation eg air compressors, coolers, dryers, receivers, distribution equipment, fluid plumbing and fittings, drain traps, FRL air service units, valves, actuators, seals.Performance characteristics: air compressors eg volumetric efficiency, compression ratio, isothermal efficiency; hydraulic pumps eg operating efficiency, losses, flow rate, operating pressure, shaft speed, torque and power.
Be able to design pneumatic and hydraulic circuits. Pneumatic circuits: eg directional control, piloted control, reciprocating control, logic, memory, multi-actuator circuits with sequential operation, cascading techniques, stepper circuits, pulsed signals, latching circuits, direction and speed control of rotary actuators and air motors. Hydraulic circuits: eg sequential operation of multi-actuator circuits, regenerative circuits, counterbalance circuits, 'meter-in' and 'meter-out' circuits, bleed-off circuits, direction and speed control of hydraulic motors. Electro-pneumatic and electro-hydraulic circuits: use of electronic logic devices and systems and their interface with fluid power circuits; solenoid valve arrangements.
