PLC Ch 5 Exam Questions and Answers
100% Pass
What does a memory map for a typical PLC processor consist of? - ANS Several areas, Some
of these having specific roles
Compare the functions of the PLC program and data files - ANS 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? - ANS Type of data they contain
List 8 different types of data files use by SLC 500 controller - ANS 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? - ANS . 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? - ANS 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. - ANS 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.
copy the status of all of the input terminals to the input image table. If an input is active
example there is electrical continuity the corresponding bit in the input image table will be set
to a 1.
