6 BASIC INSTRUCTIONS
6.1 Comparison Operation Instructions
Comparing 32-bit binary data
LDD(_U), ANDD(_U), ORD(_U)
These instructions compare the two sets of 32-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 >=.

■Description, range, data type
• In safety programs executed by the Safety CPU, only safety devices and safety labels of data types described in the table
can be used.
