Must use at least the following and at least one time:

- Start momentary PB/Stop momentary PB/ Internal bit hold
- 2 SQO instructions
one for output conditions for each step
one for time requirements for each step
- B3 Bit Data File for one SQO
- N7 Data File for the other SQO
- Timer
- MOV
- Reset PB

- You're creating a basic washing machine process using 2 sequencers
- There are to be 7 process steps with 7 "Real-World" outputs
- The steps and process times for each output are listed below:

1. Fill for wash (solenoid) 4 sec.
2. Wash (motor) 5 sec.
3. Drain (light 1 green) 3 sec.
4. Fill for Rinse (solenoid 2) 4 sec.
5. Rinse (motor) 5 sec.
6. Drain and Spin (light 1 green and light 2 yellow) 6 sec.
7. Stop and Sound Buzzer (light 3 red and buzzer) 2 sec.

[Start PB - I/0, Stop PB - I/1; Light 1 - O/0, Light 2 - O/1, Light 3 - O/2, Buzzer - O/3, Solenoid 1 - O/4, Solenoid 2 - O/5, Fan - O/6]

- There must be a "Home Process Step" when the cycle is started
- Sequence must stop and automatically reset last "process step"
- If the sequencer is stopped for any reason the real world outputs must de-energize
- Program must be retentive
- If there is a power loss or Stop PB that interrupts the sequencer, when power is returned the sequencer must pick up exactly where it left off. You must use the physical, momentary Start PB to restart the sequencer in this circumstance.
- The Reset PB will de-energize all outputs and allow the operator to push the Start PB so the process runs from the beginning with a home process step with no outputs

Goodluck!
