Objectives

The main goal of this course is to provide students with skills to design and develop control and supervision applications for discrete-based industrial automation systems.

Learning outcomes and competences

a) Understand the characteristics and requirements of automation systems employed by different types of industries.

b) Describe the behavior of control applications for discrete event systems using formal languages such as Grafcet. 

c) Develop control applications for automation systems based on specific languages for industrial processes, supported on PLC/SoftPLC platforms.

d) Develop supervisory and monitoring applications for automation systems based on SCADA systems (Supervisory Control and Data Acquisition).

e) Understand complementary technologies used in automation systems: industrial sensors and automatic identification systems (Barcodes & RFID).

 

Working method

Presencial

Program

a)  Modelling discrete event systems using Grafcet.

b)  Programming model for industrial controllers: IEC 61131-3.

c) Supervision and monitoring systems: human-machine interfaces (industrial HMI) and SCADAS.

d) Platforms for control applications: Programmable Logic Controllers (PLC) and SoftPLC.

e)  Industrial sensors and automatic identification systems: barcodes and RFID.

Eligibility for exams

-- Attendence of 75% of classes (University of Porto regulations).

Calculation formula of final grade

Evaluation components and correspondent weights in the final classification:

- Final exam component (EC), with the following weight:
------ Final Exam (EX), 35%

- Distributed component (CD) with the following weights:
------ Laboratory work (TL): 45%
------ Mini Test (MT): 15%
------ Micro Tests (UT): 5%

- The EC component may be subject to grade improvement.
- The CD component is not subject to grade improvement.

-- Students who failed UC in previous years:

• They may maintain the classification obtained in the TL or MT component as long as it is >= 10.
• They must perform the EX and UT components.

- Students who have been approved at UC the previous year and want to improve their grade:

• They must perform all components (CE and CD).

For the purpose of explaining the final classification formula consider that:
- T = (0.35*EX + 0.15*MT + 0.05*UT)/0.55
- P = TL
- All grades on a 0... 20 range.

- For approval it is necessary to obtain a minimum grade of 7.00 values in both components T and P.

- Consistency between group and individual grades: the grade in component P cannot be 5 (five) higher than the grade of component T. The opposite does not apply.

- Final Classifications> = 18 values may be conditional on the completion of an oral exam.

- Final Classification (CF):

IF (P>=7.00 E T>=7.00) THEN
       IF (P>T+5) THEN TL=T+5
       CF = 0.35*EX+0.15*MT+0.05*UT+0.45*TL
ELSE
       CF=RFC /* reprovado por falta de componente */
END_IF

Examinations or Special Assignments

Students with statutes (workers, association leaders, sportsmen, special needs, etc.) will have an evaluation process equal to the rest of the students.

Special season exams and course completion:

- Students who have not completed the TL or MT components will have to take an equivalent test.
- Students who have not completed the UT component apply the following: in the final grade formula (CF) component EX will have a weight of 40% considering that UT= 0%.

Internship work/project

Special assessment (TE, DA, ...)

Classification improvement

The laboratory part is not subject to a grade improvement.
