8.8
Character String Operation Instruction
Comparing character strings
LD$
, AND$
, OR$
These instructions perform a comparison operation between the character string data in the device specified by (s1) and later
and the character string data in the device specified by (s2) and later. (Devices are used as a normally open contact.)
*1 Supported by engineering tool version "1.035M" and later.
*2 EQ is =, NE is <>, GT is >, LE is <=, LT is <, and GT is >=.
