Compare Instructions

The compare instructions let you compare values by using an expression or a specific compare instruction.

Available Instructions
 

If you want to:	Use this instruction:
compare values based on an expression	CMP
test whether two values are equal	EQU
test whether one value is greater than or equal to a second value	GEQ
test whether one value is greater than a second value	GRT
test whether one value is less than or equal to a second value	LEQ
test whether one value is less than a second value	LES
test whether one value is between two other values	LIM
pass two values through a mask and test whether they are equal	MEQ
test whether one value is not equal to a second value	NEQ

You can compare values of different data types, such as floating point and integer.

The bold data types indicate optimal data types. An instruction executes at its fastest and with it lowest memory requirements if all the parameters of the instruction use the same optimal data type, typically DINT or REAL
