Internal PLC IO Requirements
- 10x24V DC input for can sensing (would it be worth multiplexing this?)
- 7x24V DC input for front door buttons (ditto with the multiplexing question)
- 1x24V DC input for manual dispense mode button
- 10x?110V? relay outputs (this assumes linear actuators return by themselves)
- 7x DC outputs for empty slot display
