Instruction 42- Double Word Equal To
Expression:
Space Requirement: 1 line x 5 column Location Requirement: Middle, Right rail
Function:
When the input is ON, the data of A+1.A and the data of B+1.B are compared, and if A+1.A is
equal to B+1.B, the output is turned ON.
Execution Condition:
Input Operation Output
OFF No execution OFF
ON Execution A+1.A = B+1.B ON
A+1.A ≠ B+1.B OFF

Example:
When B010 is ON, the double-word data of D0101×D0100 is compared with the double-word
data of D0251×D0250, and if the data of D0101×D0100 is equal to the data of D0251×D0250,
B014 is turned ON.
If the data of D0101XD0100 is 250000 and that of D0251XD0250 is 250000, the comparison
result is true. Consequently, B014 is turned ON.
If the data of D0101x D0100 is -100 and that of D0251xD0250 is 0, the comparison result is false.
Consequently, B014 is turned OFF.
