7 BASIC INSTRUCTIONS
7.1 Comparison Operation Instructions
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) and according to the result (small, equal, large), (d), (d) + 1, or (d) + 2 is
turned ON.
• (s1) and (s2) are handled as binary values within the range of above data setting.
• Large and small comparison is executed algebraically.
Precautions
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)
• Without sign…
32767 (7FFFH) < 65280 (FF00H)
(1): Even if the command input turns OFF and the CMP instruction is not executed, (d) to (d)+2 latches the status just before the command input turns from ON
to OFF.
Error code
