Students will learn I/O interfacing between the PLC controller and HMI devices. Once the HMI design process is complete and understood, students will be instructed in how to write ladder logic programs to control several real machines in the lab. In addition the student will be instructed in writing diagnostic programs to monitor the machines operation and display the errors on the HMI screen.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services; contact the ASSIST office in the Instructional Support Services department. All students are expected to fulfill essential course requirements. The College will not waive any essential skill requirement of a course or degree program.

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton’s Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton’s policies and procedures provide students  a fair hearing if a complaint is made against you.  If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Details of the Code of Academic Conduct can be found in the Student Handbook.

Introduction to HMI programming software, tag lists, push button assignment, indicator windows and interfacing techniques between the PLC and HMI devices.

LAB project to complete the HMI interface design to work with lab 10 from the previous class. In the project the student must operate the previous lab functions through the HMI interface as well as provide diagnostic error messages that will be displayed on the HMI device.

Continuation of the LAB project started in class 2.

IIntroduction to the HIRATA board testing machine located in the back of the lab. Discussion on how the machine functions, I/O list and how to design the HMI interface to it. Finish up the lab previously started.

Introduction to the Tech Track assembly system located in the lab. Discussion on how the machine is to function, I/O list and how the HMI interface should be designed to operate it.

First test.

All students will be broken up into lab groups and assigned to work on one of the 2 machines located in the lab area. (HIRATA or Tek Track) These will be complete machine design programs and will take several weeks to complete. The instructor will be available during the next class secessions for consultation and advice on how to program and debug these control programs. When a group finishes their program, and the program is signed off by the instructor, they can begin to work on a program to control the other machine.

Final test and all lab projects due for completions.

Sample programs and lab I/O lists.

• 2 tests will be given as shown on the topic outline.

• 3 lab projects must be completed for a perfect lab grade of 100.

• The 2 test grades will be averaged with the lab grade for a final grade.

Safety Policy

General:
Your instructor will cover the following safety concerns at the beginning of the class.

As the course progresses the instructor will cover safety concerns in machine control system programming and control systems design. These safety rules must be followed in the student’s own programs and program debug procedures.

No student will ever work on lab projects in the room alone. For safety sake at least 2 people must be in the room anytime students are working on lab projects.

The student understands the equipment used in this course is standard industrial grade equipment and must be used in accordance with OSHA standard industrial safety rules and regulations.

The student understands the instructor has the right to remove a student from the class for dangerous or unprofessional behavior.

If at any time a student notices a safety concern he/she must notify the instructor immediately. This includes loose equipment, hoses, wiring or any other safety concern.
