PLC: TEST 1 Final Examination with
Guaranteed Pass Solutions 2026-2027
Updated.
PLCs were originally designed as replacements for - Answer Relay control panels
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
Status indicators are provided on each output of an output module to indicate that the - Answer
Output is active
Which model of the PLC Connects directly to the field devices such 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

Current sinking
The Allen - Bradley SLC - 500 address I: 2/4 refers to a - Answer Input module in slot 2
terminal 4
Discrete I/O modules can be classified as - Answer Bit oriented
The Alan - Bradley SLC - 500 address o: 3/0 refers to a - Answer Output module in slot three
terminal four
Which of the following specifications defines the number of field inputs or outputs that could
be connected to a single module? - Answer Points per module
Analog modules can be either voltage sensing or current sensing - Answer True
Memory elements that store information in a PLC are called bits which refers to binary digits -
Answer True
an analog signal... - Answer Can have an infinite number of states
Typically a word in a PLC is - Answer 16 bits
The electrical isolation of an analog I/O module specifies how accurately an analog value can be
represented digitally - Answer False... The resolution of an analog I/O module specifies how
accurately an analog value can be represented digitally
The location of a specific input or output feel device is identified by the processor by means of
its function - Answer False... The location of a specific input or output field device is
identified by the processor by means of its address
An analog module: - Answer Uses A/D and D/A converters
