3.1.3 Basic Programing

1) design Basic Program
  • here s my basic program
 
 


Conclusion:

1) what is the best way to make sure that all of your devices are in the correct ports of interface and have been wired correctly.
  • to label everything is the best way
2) Explain the importance of labeling blockfunctions with a flow chart
  • it makes everything organized and simple

3.1.5 Variable Functions


4) create the Program to the right
  • Initial program created



12) create notes to deterimne the process



14) how long was the light on
  • light was on for 5 seconds
Conclusion


16) Describe how you might modify the Plus command so that it can reset a variable block to 0 within an program
  • put the whole Program on a continuous loop
17) What might an industrial or manufacturing keep count or keep track of ? Describe an example
  • manufacturing line  in the car industry keeping track of the numbers of parts prodused

3.1.6

1. build support system

2. Add motor and gear box


support system and motor

5. is this an open or close loop system
  • it is a closed system
6. Where do you think the gear box would have come to rest had you set the program to cycle 120 times
  • it will stop on the same place you started
7. What problems and indecencies might this process cause if used in an assembly mechanism designed to run 24 hours a day 7 days a week
  • it would wear out the small motor
switch design

9. is this an open or closed loop system
  • closed
10. how prices would this device be if it were designed to cycle 500 times
  • it would be very precise
this is the program to run the mechanism back and forth 20 times



Conclusion

1. Describe an open loop system that has not already been given as an example
  • gas tank  

2. describe a closed loop system that ha not already been given as a example
  • elevator that we are making in class
