Text String Processing Instructions Section 3-33
S2: Text String 2
Note 1. The data from S1 to S1 + the maximum 2,047 words and from S2 to S2 +
the maximum 2,047 words be in the same area.
2. The data from S1 to S1 + the maximum 2,047 words and from S2 to S2 +
the maximum 2,047 words cannot overlap.
Operand Specifications
Description String comparison instructions compare the text strings designated by S1 and
S2. If the result of the comparison is true, an ON execution condition is cre-
ated in the ladder diagram. The maximum number of characters for either S1
or S2 is 4,095 (0FFF hex).
String comparison instructions are expressed using the 18 different mnemon-
ics listed below. (LD, AND, and OR do not appear in the ladder diagram.)
LD=$, AND=$, OR=$
LD<>$, AND<>$, OR<>$
LD<$, AND<$, OR<$
