  12. Correlate ladder programs logic with machines and process descriptions.
  13. Write ladder logic programs based on machine and process descriptions.
  14. Use on line monitoring to locate and record critical PLC status information.
  15. Discuss safety considerations in the configuration, programming and maintenance of PLC hardware and software.
  16. Discuss advanced PLC topics including analog I/O, intelligent I/O modules, PLC networking etc.
  17. Demonstrate proper and safe practices while removing and replacing PLC modules.
  18. Apply a methodical troubleshooting approach to locate malfunctioning I/O devices (switches, sensors, relays, solenoids etc.) on PLC controlled machines and processes.
  19. Apply a methodical troubleshooting approach to diagnose and correct malfunctions within the PLC itself.
  20. Explain the construction and characteristics of various cells

General Information:

Student Environment:  students at this institution are expected to adhere to standards of academic and personal behavior consistent with college-level performance.  The college commitment is measured by personal motivation, endurance, and persistence.  As a student, you must establish the required levels of time, energy, and effort needed for you to succeed at this new level.

The faculty expects students to be active participants in the education process.  Performance standards in this division are set from expectations typically found in the electronics environment.  Included in these expectations are goal setting, the use of professional values, defined personal priorities, and the commitment of adequate time for performance.  Workload for assignments is established using an expectation that two additional hours for each class contact hour is required.

Assignment Requirements:  students at this institution are expected to adhere to standards of academic and personal behavior consistent with college-level performance.  The student shall submit all assignments as required by the instructor. Performance requirements include note taking, chapter reading, equipment operation, discussion and tests.  You may be expected to complete assignments that require either typing, word processing, or computer skills.  You will be accountable for spelling, math, accuracy, and professional appearance of assignments.  Your work may be rejected if it does not reflect explained business standards.

Assignment Due Dates:  due dates for assignments will be given in class.  Each assignment must be turned in on time.  Acceptance of late assignments is at the discretion of the instructor.  The student must call the instructor prior to the due date or test date with an appropriate reason for not making it to class.  The instructor can be reached by leaving a message with a secretary at 540-7256.

Attendance: students are expected to attend all meetings of classes in which they are enrolled.  A maximum of three absences, regardless of cause, are allowed in this course.  At the option of the instructor, absences in excess of this amount will result in one of the following: the student will be administratively withdrawn; or the student's final grade will be reduced by five points per excess absence.  If absences are unavoidable, students are expected to assume responsibility for keeping up to date with course progress.

Attendance Restricted:  College policy permits only enrolled students, administrative personnel, and persons attending with the permission of the instructor to be present in the classroom or laboratory or shop during scheduled classes.  The instructor may remove from the classroom and temporarily suspend from class any student whose conduct the instructor determines is obstructive, disruptive, hazardous to property or person, or otherwise unacceptable.

Grading Criteria:  this course makes available a pre-determined number of points which each student may earn.  Final grades will be determined by the total points earned by each student.  Total points of the course may be adjusted by the instructor.  Points will be earned from tests, technical reports, drawings, verbal and visual presentations.  Grades are determined by the instructor as they pertain to electronics industry standards.  All exams will be scheduled and shall be taken without use of reference.

Only under extreme circumstances will "make-up" tests will be administered. Justification for taking make-up test/s must documented or verifiable, will be administer on the first day returned to class, and reduced by one letter grade.

FINAL GRADES

A =            90 to 100% of all possible points
B =            80 to  89% of all possible points
C =            70 to  79% of all possible points
D =            60 to  69% of all possible points
U =            below 60% of all possible points

Withdrawals:  Drop with a refund is possible during the first 15 percent of the term.  An official withdrawal may also be initiated by the student through 80 percent of the term resulting in a grade of “W.”  A “W” grade has no credit and is not computed in the GPA.  If you simply stop attending without officially withdrawing, a grade based on the total points earned will be assigned to you at the end of the term as per the grading policy listed in the syllabus.  This will usually result in an “F” grade on your grade report and may not be changed to a “W” once it is issued.  Consult a current class schedule for the last date to withdraw.  Important Note:  Withdrawal for any reason after the official term “Drop Date” (first 15% of the term; see PPCC Semester Schedule) will result in the student forfeiting the Colorado College Opportunity Fund (COF) credit in an amount equal to this course’s credit hours.  Consult a current class schedule or the PPCC calendar http://www.ppcc.edu/AdmissionsEnrollment/CollegeCalendar/

Incomplete:  An Incomplete “I” grade will be issued only if the student has completed more than 75 percent of the course requirements, and has an emergency that cannot be resolved prior to the end of the semester.  An Incomplete “I” is rarely issued and may pose some risk to your GPA.  All remaining work must be satisfactorily completed by the contracted date prior to the end of the next semester or a grade of “F” will be issued for the course.

Audit:  Students may choose to take this course for audit.  Normally, the audit option should be declared at registration; however, students may change their registration from credit to audit up to the current term “Drop Date” (first 15% of the term) published in the PPCC schedule.  The request to change to audit must be done on a semester  registration form and must receive written recommendation by the Languages Division Dean and be approved by the Vice President for Educational Services prior to the published “Drop Date.”  Once an audit status is approved, the decision is irreversible.  Audit grades do not transfer and are not computed in the GPA.  Courses taken by audit do not count toward enrollment status for financial aid or veterans’ educational benefits.  Important Note:  Audit courses are not eligible for the Colorado College Opportunity Fund (COF) stipend.  Students are responsible for the additional tuition amount per credit hour audited that would normally be covered by COF.

Americans With Disabilities Act (ADA): Any student eligible for and needing academic adjustments or accommodations because of a disability is requested to speak with the instructor either before class begins or during the first week of class and contact the Office of Accommodative Services and Instructional Support (OASIS) (540-7128).

Students should make an appointment with their instructor during the first week of class and bring the Disability Services Notification For Faculty form from OASIS that specifies the accommodation(s) needed for their class. All arrangements for accommodations must be agreed upon, in writing, and signed by the student, an OASIS Disability Specialist and the instructor (unless accommodations are received electronically). Because accommodations are not retroactive, it’s best to obtain accommodations before the first week of class. Also: “It is the student’s responsibility to self-advocate for approved accommodations that are not being provided since accommodations cannot be provided retroactively.” (As per the PPCC catalog)

Please contact OASIS if you are struggling with a full time course load only to qualify for health insurance benefits, whether or not you have a disability.

Student Conduct:  You are expected to always do your own work.  Academic dishonesty is defined as the unauthorized use of assistance with intent to deceive a faculty member or another person assigned to evaluate work submitted to meet course and program requirements. Review the policy on student conduct in the college catalog or on the PPCC website:
