5.4.6 Equal (=)
( 1 ) Operation
Input data A and input data B are compared and the result is stored in the bit output.
( 2 ) Format
( 3 ) Programming Example
In the following programming example, the INC instruction on the right end of the line is executed because the com-
parison is true and turns the output ON; that is, input data A is equal to input data B when input data A in MW00000 is
100 and input data B is 100.
With real number data, the value displayed by the MPE720 may not match the execution result of the comparison instruction
due to a slight precision error.

TRUE: Output ON
FALSE: Output OFF
