PLC TEST 1 ACTUAL EXAM WITH
QUESTIONS AND ANSWERS 2025
, PLCs were originally designed as replacements for - ANSWERRelay control panels
Field or real-world devices refer to - ANSWERAll devices physically wired to the PLC
The output interface module connects to - ANSWERLoad devices such as lamps or
solenoids
Scan time is the time required to - ANSWERExecute one cycle of the total program
The programming device must be connected to the controller to run the program -
ANSWERTrue programming devices used to enter desired program into the memory of
the processor
Programmable logic controller's are categorized according to the - ANSWERNumber of
I/O points
One disadvantage of modular I/O is it's lack of flexibility - ANSWERFalse... PLCs with
the modular I/O consist of divided compartments into which separate models can be
plugged this feature greatly increases the designers options and the units flexibility

devices and convert them into signals that can be used by the processor
Module inserted into the wrong slot could be damaged - ANSWERTrue... He module
inserted into the wrong side could be damaged by improper voltage is connected
through the wiring
Status indicators are provided on each output of an output module to indicate that the -
ANSWEROutput is active
