Two different processes require the same input and output field devices; two toggle switches, two pilot lights, and one motor. Which statement is true? a. The input and output field devices do not have to be rewired when switching the programs of the processes unless the physical addresses change.
b. Each process has 4 inputs and one output.
c. The two processes can be executed simultaneously using the same input/output devices.
d. The two toggle switches may be wired in parallel to the same input port. Similarly the two pilot lights may be wired in parallel to the same output port of the PLC.
