Explain the purpose and functionality of the EXAMINE ON instruction.
What will be an ideal response?
Whenever the processor sees an N.O. contact in the user program, it views the contact symbol as a request to examine the address of the contact for an ON condition. If the N.O. contact has an input address, and if the real-world input device is closed, or ON, the processor sets the appropriate bit in the input register to 1, or ON. As the EXAMINE ON instruction is looking for an ON condition, a bit set to 1, or ON, is a true condition, and a logic path exists through the contacts. If the real-world input had been open, or OFF, the processor would have cleared the appropriate bit to 0, or OFF, and the contact would be false as far as the logic of the ladder diagram was concerned and would not allow a logic path.

What will be an ideal response?
Elias wants to perform an after-tax evaluation of equivalent methods to electrostatically remove airborne particulate matter from clean rooms used to package liquid pharmaceutical products. Two alternatives are available, but others may be identified if these are not acceptable. Using the information shown, MACRS depreciation with n = 3 years, a 5-year study period, after-tax MARR = 7% per year, Te = 34%, and a spreadsheet, he obtained the results AWG = $ ? 2176 and AWH = $3545. Any tax effects when the equipment is salvaged were neglected. Thus, with MACRS depreciation, method H is the better method. Use classical SL depreciation with n = 5 years to evaluate the same alternatives. Is the decision different from that reached using MACRS?
