Deck 13: Data Manipulation

Question 1

The ____________________ is the address that contains the value examined to determine if it is inside or outside the specified range.

Answer 1

test value

Question 2

The limit test instruction is true until it detects that the test value is within certain limits.

Answer 2

False

Question 3

____________________ is a constant (numeric value) or an address that determines the upper limit of the test range.

Answer 3

High limit

Question 4

In the Allen-Bradley MOV instruction, constants such as 250, 400, 5.5, etc., can be entered into the source location of the MOV instruction rather than a memory address containing the value to be moved.

Question 5

Describe the LIM or limit test instruction.

Question 6

When the rung that holds the MOV instruction is false, the instruction moves data from the source address into the destination address on each processor scan.

Question 7

Describe the concept of data transfer.

Question 8

Most PLCs now have the ability to manipulate data that is stored in memory.

Question 9

"Data compare instructions" compare the data stored in two or more words and make decisions based on the program instructions.

Question 10

What data type is the value in the high limit?

Question 11

What are the two broad categories in which data manipulations can be placed?

Question 12

The ____________________ instruction is an input instruction that compares values from addresses or files.

Question 13

List two compare instructions included with the Allen-Bradley family of programmable controllers.

Question 14

The PLC-5, SLC 500, and MicroLogix use a(n) ____________________ instruction for moving data from one word to another.

Question 15

____________________ is a constant, or an address that determines the lower limit of the test range.
