7.9 Real Number Instructions
Comparing single-precision real numbers
LDE, ANDE, ORE
These instructions perform a comparison operation of a single-precision real number. (Devices are used as a normally open
contact.)
*1 The engineering tool with version "1.035M" or later supports the ST.
*2 EQ indicates =, NE indicates <>, GT indicates >, LE indicates <=, LT indicates <, and GE indicates >=.
