the lab consists of making a program to run similar to a washing machine. it includes, lights, motors, push buttons and selector switches.
One fellow classmate tried to do sequencing for the program. He had issues about resetting the program. It wouldn’t all reset at the same time.
We use ladder logic to program the PLC’s.
so i ask the great people at CD to help me out.
the lab goes as follows:
Wash the clothes for 3 minutes
spin the clothes for 30 seconds
-rinse the clothes 3 minutes
final spin for 30 seconds
come to a stop
washing cycle includes:
-level selector (high, medium, and low level loads)
-water temperature (hot, warm, cold water)
-cold water is added during the spin cycle (3 times, 3 sec. each)
-lights to indicate which cycle the machine is in
-red light to indicate the whole cycle is done
-lights to indicate hot and cold water being added (separately)
the issue at the moment is i can select cold wash, it does it thing and then when it’s over it resets back to the top of the program. then when i try to select warm water wash, it will not function. It will only stay on the cold wash cycle. It is not fully resetting the program so that i can select cold water wash, and then warm water wash once cold is done, and then some other kind of wash.
