CERTIFICATION EVALUATION TEST PAPER
QUESTIONS SOLUTIONS GRADED A PLUS
◉ Field or real-world devices refer to.
Answer: All devices physically wired to the PLC
◉ The output interface module connects to.
Answer: Load devices such as lamps or solenoids
◉ Scan time is the time required to.
Answer: Execute one cycle of the total program
◉ The programming device must be connected to the controller to
run the program.
Answer: True programming devices used to enter desired program
into the memory of the processor
◉ Programmable logic controller's are categorized according to the.
Answer: Number of I/O points
◉ One disadvantage of modular I/O is it's lack of flexibility.
,Answer: False... 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
◉ Standard programming language used to develop a series of
instructions that direct the PLC to execute actions is.
Answer: Ladder logic
◉ One function of a PLC input interface module is to.
Answer: Except signals from field devices and convert them into
signals that can be used by the processor
◉ Module inserted into the wrong slot could be damaged.
Answer: True... He module inserted into the wrong side could be
damaged by improper voltage is connected through the wiring

as pilot lights motor starters and solenoids.
Answer: Output
, ◉ Discrete means that each output or input has two states: true on...
false off.
Answer: True
◉ A _____ is an example of an actuator that could be controlled by
discrete output from a PLC.
Answer: Motor starter
