PHYS7004 - Industrial Comms & Networks

banner1
Title:Industrial Comms & Networks
Long Title:Industrial Communications & Networks
Module Code:PHYS7004
 
Credits: 5
NFQ Level:Intermediate
Field of Study: Physics
Valid From: Semester 1 - 2011/12 ( September 2011 )
Module Delivered in 2 programme(s)
Module Coordinator: Donagh OMahony
Module Author: DENIS POLLEY
Module Description: This module covers the underlying principles behind today's industrial communications systems. The OSI model (and variations) is studied as a means of understanding the relevant functional layer tasks which underpin the comms protocols. Practical protocols & network buses are emphasised, such as Foundation Fieldbus, Modbus, ControlNet, EtherNet/IP etc. Wireless industrial protocols are also addressed.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Provide a detailed description of the OSI reference model and explain how the basic principles of all communications protocols and systems are derived from this.
LO2 Describe a selection of flow control protocols and associated message framing concepts.
LO3 Assess a range of core Industrial protocols and related Media Access techniques.
LO4 Appraise Industrial Network bus architectures and the sensors and intruments appropriate at various levels in the hierarchy.
LO5 Survey the popular Wireless Industrial Communication technologies.
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
