Answer 1

NEQ
not equal (NEQ)

Question 2

The compare instruction used to perform a simple comparison,
e.g., Counter_A.ACC>Data, is performed faster and consumes less memory than using the greater than instruction.

Answer 2

False

Question 3

When using comparison instructions, source A must be a tag, whereas source B can be a tag or a(n) ____________________.

Answer 3

constant

Question 4

Question 5

List six operators that can be used with the compare instruction.

Question 6

Question 7

The CMP instruction can be used to evaluate two ASCII strings. What does it mean for two strings to be equal?

Question 8

Provide a description for the LEQ instruction.

Question 9

If you want to program an expression using comparison operations, use the ____________________ instruction.

Question 10

When source A and source B are tested using the LES instruction, the instruction will be true if A is equal to B.

Question 11

The ControlLogix comparison instruction for testing two limits to determine if they are within a predetermined range is the ____________________ instruction.

Question 12

Programming the limit test instruction consists of entering three parameters: low limit, test, and high limit.

Question 13

The GRT instruction determines whether one source of data is greater than or equal to another.

Question 14

Comparison instructions are input instructions that test two values to determine whether the instruction is true or false.

Question 15
