| Module Description: |
This module familiarises the student with the concepts of programmable control in automation. On completing the module, the student will have developed a clearer understanding of the application of PLC’s and will also be aware of safety requirements and the peripherals associated with PLC’s in automated plants. |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
Describe and specify types of input tranducers/sensors and other switching devices associated with PLC inputs for industrial processes. |
| LO2 |
Describe the input output interface circuits and their role in the PLC's reliability. |
| LO3 |
Use a number of PLC programming languages to develop control solutions. |
| LO4 |
Test, debug, and rectify programs using software tools. |
| Pre-requisite learning |
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s). |
| No recommendations listed |
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list. |
| No incompatible modules listed |
