7 BASIC INSTRUCTIONS
7.1 Comparison Operation Instructions
Processing details
• These instructions perform a comparison operation on the 16-bit binary data in the device specified by (s1) and the 16-bit
binary data in the device specified by (s2) with the 16-bit binary data in the device specified by comparison source (s3), and
according to the comparison result (below, within zone, above), (d), (d) + 1, or (d) + 2 is turned ON. (s1), (s2), and (s3) are
handled as binary values within the range of above data setting. Large and small comparison is executed algebraically.
• Large and small comparison is executed algebraically.
Precautions
• Set (s1) to a value less than (s2).
• Three devices are occupied from the device specified in (d). Make sure that these devices are not used in other controls.
Operation error
• With sign…
-10 (FFF6H) < 2 (0002H) < 10 (000AH)
• Without sign…
0 (0000H) < 32767 (7FFFH) < 40000 (9C40H)
(1): Even if the command input turns OFF and the ZCP instruction is not executed, (d) to (d)+2 latches the status just before the command input turns from ON
to OFF.
