7 BASIC INSTRUCTIONS
7.1 Comparison Operation Instructions
167
7
Comparing 32-bit binary data
LDD
(_U), ANDD
(_U), ORD
(_U)
These instructions perform a comparison operation between the 32-bit binary data in the device specified by (s1) and the 32-
bit binary data in the device specified by (s2). (Devices are used as NO contacts.)
*1 Supported by engineering tool version "1.035M" and later.
*2 EQ is =, NE is <>, GT is >, LE is <=, LT is <, and GT is >=.
