Manufacturing Engineering and Technology. After learningabout this system, the students will come to know the importance of measuring the parameters inreal time. They will also come to know about the issues involved in measuring, interfacing and Page 4.360.5reading the parameters in real time. The following exercises are planned for inclusion in thecourse delivery.1. In order to measure the torque in either lbf. or N-m, what settings are required? How to keep the corresponding setting by configuring the Labview block diagram and front panel?2. In order to measure the instantaneous or average power, what adjustments are to be made?3.

while stillachieving each milestone in the design process requires substantial planning and facultyinvolvement. A suitable solution for the junior level is limitation of the components to some setthat is both universally available and sufficiently understood by the students. The use of rigidmilestones can also be implemented, but can be left somewhat open. As an example, a sensingmodule might have a milestone of generating a sensing system that outputs a voltage between ±5volts with a range of at least one foot for a given test light. The details regarding theimplementation that we have chosen, as well as selected results of the procedures, are discussedin Sections 3 and 4.3.

In addition, the incremental shaft encoder scheme provided with theBrain board was not continued because reliable operation could not be achieved. Plans are touse a more robust wheel position encoder scheme in the future. The following is a briefdescription of the sensors mounted on each MOBOT and the tests that the students perform:Photocells: Light-detecting phototransistors are mounted on the left and right side of the Brainboard.

This permits the execution and observation of experiments without incurring Page 4.402.2delays associated with the relocation of students from the lecture room to the laboratoryfacilities. Furthermore, a small laboratory space that could not accommodate the simultaneouspresence of many students can be effectively made accessible to the entire class, saving onundesirable overhead costs associated with logistics planning and instructor time.

The first two issues, PLC language standards and the scarcity of good PLCinstructional materials, are addressed in this paper.Teaching PLC Programming LanguagesThe absence of a standard for PLC languages creates a number of problems when instruction inPLC concepts is planned. Two options are available to overcome this issue: teach PLCprogramming using a generic set of PLC commands or select an industrial PLC and teach PLCprogramming using the command set from the selected vendor. The first option is often used inPLC textbooks so that the text appeals to a wide range of schools using different PLC systems inthe laboratory. A major disadvantage to option one is that a simulator or virtual generic PLC isnot available to
