Module purpose
The aim of this module is to further develop student control system and programming

For consolidation, the material in this module should be linked with, and
complemented by, relevant on job skill practice or other equivalent experience.
A suggested program for learning strategies is given below:
 Learning outcome 1

Since this module has a large “hands on” component, when student spend most of
the class time actually programming a testing the PLCs and PCs( at their own
speed ) the predominant teaching/learning strategy should be self paced.
An industry visit is recommended to show PLC control applications and
installation“ at work “
To ensure that the successful operation of student ‘PLC’ and PC programs is
essential their own work, it is recommended that “ group work “ be discourage at
this point. Also, it is important that PLC simulator units are available for each of the
students.
Learning Outcomes
On completion of this module the learner will be able to:
Learning Outcome 1
Briefly describe the basic control system models and given typical examples.
Compare the continuous control plans of proportional, integral and derivative in
terms of system response to an external disturbance.
Assessment Criteria
Differentiate between open and closed loop control
Compare Feed – forward and Feed – back control systems and give
examples.
Define and relate the terms: error signal, measured, value, and set point, by
giving examples of their application in industrial control system with
proportional, integral, derivative, and PID control.

The following equipment list is suggested for a class of twelve ( 12 )
students.



Twelve (12) programmable controllers (PLCs) complete with
simulators for testing purposes.
Market entry “shoebox” type with 20 I/O, built in 24V DC input power
supply, sink input (ie PNP open collector transistor type) and reply
outputs. A typical example here is Mitsubishi’s F1-20MRES .
The simulator unit (hardware to the PLC), should have momentary
push buttons for the first two outputs, and SPST toggle switches for
the remaining input. The switches should be labelled to avoid
confusion.
The output LEDs on the PLC output module should be sufficient to
show tested program operation.
Six (6) pocket programmers to suit above PLCs.
Six (6) personal computer (PC) software programming “ Kits”
consisting of software and manuals, plus PLC to PC interface units
and cables. Mitsubishi’s “ Medoc” software is a typical example.
Six (6) 80386SX, 1Mb RAM, 40Nfb HD, VGA Personal Computers
(PC). These are for PLC programming monitoring and
documentation, plus the direct computer control exercises.
Six (6) copies of programming software and manuals such as BASIC
or TURBO PASCAL – required for direct computer control.
Six (6) latching I/O cards for insertion in the PC motherboard. An
example is Boston Technology’s PC-36 card based on Intel’s 8255
microprocessor chip.
Six (6) optical-isolator input cards. These would be mounted
externally to the PC and can also be supplied by (amongst others)
Boston Technology.
Six (6) relay output cards. Also connected externally and supplied by
Boston Technology.
A basic range of small pneumatic cylinders (eg 20NB x 100 stroke
complete with reed switches at each stroke end), solenoid control
valves (single and doubles, with 12V or 24V solenoids), flow control
valves, quick-connect couplers, air-service units, distributors and
lengths of plastic air lines. SMC or FESTO can supply suitable
equipment.
This
equipment
is
required
for
the
programming/connection exercises using the PLCs and later the
PCs.
Finally, all the “normal” classroom facilities are required, such as a
whiteboard, overhead projector and screen, plus video replay facilities.

University.
Ensure that all PLC input sensor devices are compatible with the PLCs
used.
While not essential, the following PLC peripherals could also be used:
 Digital to Analogue converters
 High speed counters
 Position control units
 Input/Output (I/O) extension units.
