The immediate input and output instructions provide a way of:

A) ending the program immediately.
B) restarting the program immediately.
C) temporarily interrupting the program scan to allow selected bits in the data table to be updated.
D) temporarily interrupting the program scan to reset all bits in the data table to zero.

Immediate Input

Refers to a type of input in programmable logic controllers (PLCs) that is processed as soon as the state change is detected without waiting for the rest of the program to be executed.

Immediate Output

An output action in a control system that occurs directly in response to an input condition without delay.

Program Scan

A program scan is the sequential process by which a programmable logic controller (PLC) or controller cycles through its instructions to control connected devices.
