am a count-up to keep track of the parts brought into the storage room by the CONVEYOR_IN and detected with a PROXIMITY_IN sensor.
2. Program a count-down to keep track of the parts taken out of the storage room by the CONVEYOR_OUT and detected with a PROXIMITY_OUT sensor.
3. Both conveyor motors are operated by one START/STOP seal-in pushbutton station.
4. A GREEN light must be on if the part count in the storage room is equal to zero (0).
5. A YELLOW light must be on if the part count in the storage room is between one (1) and ten (10) (inclusive).
6. A RED light must flash on and off in periods of 0.5 seconds if the part count in the storage room is greater than ten (10).
7. A RESET pushbutton is used to reset the count. - Program CONVEYOR_IN and CONVEYOR_OUT using bits 0 and 1 of the output module.
8. Program the GREEN, YELLOW, and RED lights using bits 2, 3, and 4 of the output module.
9. Program the START and STOP buttons as normally open in bits 0 and 1 of the input module.
10. Program PROXIMITY_IN and PROXIMITY_OUT using bits 2 and 3 of the input module.
11. Program the RESET pushbutton using bit 4 of the input module.
