Comparison Operation Instructions
Comparing 16-bit binary data
LD
(_U), AND
(_U), OR
(_U)
These instructions compare the two sets of 16-bit binary data specified. (Devices are used as normally open contacts.)
*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 >=.
