PLC Ch 5 Questions With All Correct &
Verified Answers
What does a memory map for a typical PLC processor consist of? Correct answer-Several areas,
Some of these having specific roles
Compare the functions of the PLC program and data files Correct answer-the program file is where
the ladder logic
programming is stored and the data file
portion of the processors memory stores
input an output status processor status the
status of various bits and
numerical data. all of the data stores in the
data file is stored in the data file is accessed
via the ladder logic program.
In what manner are data files organized? Correct answer-Type of data they contain
List 8 different types of data files use by SLC 500 controller Correct answer-Output, input, status,
bit, timer, counter, control, integar, and reserved.
a. What information is stored in the input image table file?
b.In what for is the info stored? Correct answer-. A. the input image table file is that part of the
program memory allocated to storing the on/off status of connected to discrete inputs.
b. The information is stored in binary.
A. what information is stored in the output image table file?
b. In what form is this information stored? Correct answer-A. the output image table file is that
part of the program memory allocated to store in the actual on/off status of connected discreet
outputs.
b. The information is stored in binary.
Out line the sequence of events involved in a P l C scan cycle. Correct answer-examine the status of
the input image table bits.
Solve the ladder logic in order to determine logical continuity.
update the appropriate output image table bits if necessary.
Copy the output image table status to all of the output terminals. power is applied to the output
device if the output image table bit has been previously set to a 1.
