7.1 Comparison Operation Instructions
■
Applicable devices
Processing details
• These instructions perform a comparison operation between the 16-bit binary data in the device specified by (s1) and the
16-bit binary data in the device specified by (s2). (Devices are used as NO contacts.)
• The following table lists the comparison operation result of each instruction.
Precautions
• When the most significant bit is "1" in the data stored in (s1) or (s2), it is regarded as a negative binary value for
comparison. (Excluding unsigned operation)
