What is the function of a PLC’s I/O (Input/Output) mapping?
A. To assign physical inputs and outputs to the PLC’s I/O modules
B. To assign virtual inputs and outputs to the PLC’s control program
C. To assign physical inputs and outputs to the PLC’s control program
D. All of the above
Answer:C
What is the function of a PLC’s I/O (Input/Output) mapping?
A. To assign physical inputs and outputs to the PLC’s I/O modules B. To assign virtual inputs and outputs to the PLC’s control program C. To assign physical inputs and outputs to the PLC’s control program D. All of the above
Explanation: I/O mapping is the process of assigning physical inputs and outputs of the PLC to the control program. It is used to establish a connection between the physical inputs and outputs of the PLC and the control program, allowing the PLC to read and control the inputs and outputs in the industrial process. This feature allows the PLC to be tailored to the specific requirements of the industrial process, making it more efficient and effective.
