List three examples of events triggered by a push-button input where the one-shot instruction can be applied.
What will be an ideal response?
Below are examples of using the one-shot instruction to start an event triggered by a push-button input:
1. One-shot can be used to reset desired conditions in a single scan.
2. You can use a push button to read the current value of a thumbwheel switch one time.
3. A momentary push-button actuation could be used to increment speed on a motor. Speed would increment one step for each push of the button.
4. A single push button could be used to start and stop a motor. The first closure of the button starts the motor and the second closure stops it.
5. Use the one-shot instruction with a math instruction to perform a calculation once per trigger.
6. A one-shot instruction can be used to bring in changing analog input data, which can be sampled at a predetermined rate.
7. Use a push button or an internal bit and the one-shot instruction to send data to output display devices.
