6 BASIC INSTRUCTIONS
6.1 Comparison Operation Instructions
Comparing 32-bit binary block data
DBKCMP(P)(_U)
These instructions compare the two sets of 32-bit binary block data specified.
*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 >=.
■Execution condition
Setting data
■Description, range, data type
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
