1. Draw the corresponding ladder logic diagram.
2. Provide a detailed description of the program functions, rung by rung.
3. Provide an allocation list of all inputs, outputs, memory relays, counters, timers, etc.
4. A summary of how each program was developed and any difficulties encountered with each exercise.
5. Develop electronic ladder logic files (programs) that must run, so that the program functions can be validated. (You can use any free software/program...just let me know the one you are using).In industry, plant conditions are monitored and, if there are problems, it is necessary to have some way of indicating such problems. An indicator system of this type is called an Annunciator.
Exercise - Annunciator
A typical alarm system uses the following sequence to indicate a plant alarm condition to an operator
(i) System healthy - no indication.
(ii) System in alarm - a flashing Amber light and audible alarm. It shows the graphics simulation of the alarm system.
1. If the operator presses the ACCEPT button when the plant is in alarm above), the audible alarm stops and the flashing Amber light changes to permanently 'ON'.
2. If the plant drops out of the alarm condition before the ACCEPT button is pressed, the panel will show a flashing Green light. The Audible alarm and Amber light will go 'OFF'.
3. If the ACCEPT button was pressed when the plant is healthy as in 2 above, the flashing Green light will go 'OFF'.
4. There should be a LAMP TEST button which, when pressed, will light all lamps and sound the audible alarm.
5. Write a program that will operate the Alarm Simulation, using the following inputs and outputs and whatever Timers and Flags are required.
IPO = Plant alarm condition OPO = Amber Lamp
IPI = Operator accept button OP1 = Green Lamp
IP2 = Lamp test OP2 = Audible Alarm
6. Use the comments facility to describe the operation of the program

Find probabilities from a standard normal distribution
: One way to find probabilities from a Standard Normal Distribution is to use probability tables, which are located inside the front cover of your textbook.According to the table, what is the probability when z ≤ -1.75? The probability when z ≤ 1.75?
