You can use the Digital Input block to:
- Provide alarming.
- Represent items such as limit switches, valves, alarm contacts, and motor auxiliary contacts.
- Assign descriptive labels to digital values through the Open (Labels) and Close (Labels) fields to make these values more meaningful to the operator.
- Assist in control situations such as direct digital control when chained to a PID or On-Off Control block.
- Pass values to other blocks through the Next Block field.
