PLC help and sequencing
Hey, im at a stand still with one of my labs.
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)
thanks!
