BIA207S

Unit Description and General Aims

The objective in presenting this unit is to impart to students knowledge of automation and supervisory control schemes of entire systems. The subject matter covered in this unit will include an in-depth study of Applied PLC principles. This information will then be contextualized in Distributed Control Systems (DCS) and Supervisory Control And Data Acquisition (SCADA) systems. SCADA systems will subsequently be examined in considerable depth covering: fundamentals – hardware, alarms interfaces, and etc.; plant-wide communication systems; and, Object Linking for Embedding Process Control (OPC).

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

1. Evaluate Applied PLC principles in relation to process control systems, manufacturing processes, DCS, safety instrumented systems (SIS), data communications etc.
   Bloom’s Level 5
2. Demonstrate a good understanding of DCS system layout, configuration, programming, interface, reporting and maintenance.
   Bloom’s Level 6
3. Examine SCADA system fundamentals including configuration, hardware, software, interface etc.
   Bloom’s Level 4
4. Evaluate the Wide Area Network (WAN) technologies for SCADA systems.
   Bloom’s Level 5
5. Apply Object Linking and Embedding (OLE) for Operator Process Control (OPC).
   Bloom’s Level 6
6. Design safe and secure systems after evaluating security threats
   Bloom’s Level 6

Project and Unit Review

In the final week, students will have an opportunity to review the contents covered so far. Opportunity will be provided for a review of student work and to clarify any outstanding issues. Instructors/facilitators may choose to cover a specialized topic if applicable to that cohort.
