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<$
