The status bit of switches and pushbuttons connected to a PLC is stored in the:
A) input image table file.
B) output image table file.
C) user program.
D) All of these choices are correct
Status Bit
A binary indicator used within computing and digital electronics to represent the current state or condition of a system or component.
Switches

Final Answer :
A
Explanation :
The input image table file stores the current status of all the inputs connected to the PLC, including switches and pushbuttons. The output image table file stores the status of all the outputs controlled by the PLC. The user program uses the status of the inputs stored in the input image table to make logical decisions and control the outputs stored in the output image table. Therefore, the correct answer is A, as the status bit of switches and pushbuttons connected to a PLC is stored in the input image table file.
