7.1
Comparison Operation Instructions
Comparing 16-bit binary data
LD
(_U), AND
(_U), OR
(_U)
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.)
*1 Supported by engineering tool version "1.035M" and later.
*2 EQ is =, NE is <>, GT is >, LE is <=, LT is <, and GT is >=.
