PLC Lab #21

For this lab, you are to design a program that will run a 24 hour clock on the micrologix 500 PLC, using Logix 500 programming software. Your clock will be used to turn on a light at a specific time, and turn the light off after a definite interval. The accumulated values entered into the timers and counters that you use will read out the actual time in military format. set your clock so that the actual time is used, and program the light to be turned on at exactly 11:20 AM and to turn off at exactly 12:50 PM. Turn on a second light at 12:40 PM and off at 1:15 PM. (You may need to study data comparision instructions in order to make this circuit operate correctly)

PLC Lab #22

A sequencer can be used to energize outputs in "steps". The steps in the sequencer can be event driven (by a transition of an input from off- to- on, for instance) or timer driven. Research the information on sequencers in chapter 12 of the text book, and look at the instruction set help information in the Logix 500 software. Then develop a time driven output sequencer to control a set of traffic lights. Use the following output designations:

Use a 3 second green light, a 2 second yellow light on each intersection. Red will be at least 3 seconds, possibly longer if necessary to accomodate other light minimum times. The sequence will be: both reds on for 2 seconds, one green on, the other remains red. The green turns to yellow while opposite remains red. Both reds for 2 seconds, then opposite green on, etc.

A selector switch will start and stop the traffic light. Once started, it will continue to sequence until the selector switch is turned off.

PLC Lab #23

For this lab, you are to design a program to control a milling operation. The Milling machine has 2 heads- one for milling, one for cutting key-ways. You are to design controls that will provide for the following:

A master on- off power switch which will provide power to a control relay and light a pilot light to indicate that power is on.

Require a delay of 5 seconds after turning on the power switch before any other operation can take place

A switch that will automatically rotate the two heads to switch their positions (1 head in use will be positioned above the work table, the other in an un-used position) a limit switch will indicate if key way punch is in position, a second limit switch will indicate if milling head is in position. Do not allow a head to operate if it is not in position above the table. Neither head can be allowed to operate until 5 seconds after it reaches the "over the table" position.

The milling head will have a forward and reverse switch and an on-off switch. There must be a 5 second delay between reversing the motor. Be sure to interlock the forward and reverse magnetic starters.

The Key Way machine will have an on-off switch. Provide a counter that will count the operations of the key way milling machine, and light a maintenance required light after 20 strokes.

design a time of day clock that will disable all operations after 5 PM until 7 AM the following day.

PLC Lab #24

In this lab, you will make use of data manipulation instructions. Add to the previous lab the necessary logic to allow the operator to over-ride the night time lock-out by entering a code. the code should be removed when the machine is turned off, once again disabling the machine during night time hours. (Hint: You might use a pushbutton to enter the code into the accumulated value of a counter, move that value into a memory register via a second switch. Use data comparision instructions to determine if the proper number was entered. Be sure to clear the register when the machine is shut down.)
