CS/CJ/NSJ Series Instructions Reference Manual (W474)
Hint
• Unlike instructions such as CMP(020) and CMPL(060), the result of an input comparison instruction
is reflected directly as an execution condition, so it is not necessary to access the result of the
comparison through an Arithmetic Flag and the program is simpler and faster.
Precautions
• Input comparison instructions cannot be used as right-hand instructions, i.e., another instruction
must be used between them and the right bus bar.
Example Programming
AND LESS THAN: AND<(310)
When CIO 0.00 is ON in the following example, the contents of D100 and D200 are compared in as
unsigned binary data. If the content of D100 is less than that of D200, CIO 50.00 is turned ON and
execution proceeds to the next line. If the content of D100 is not less than that of D200, the remainder
of the instruction line is skipped and execution moves to the next instruction line.
i
AND SIGNED LESS THAN: AND<S(312)
When CIO 0.01 is ON in the following example, the contents of D110 and D210 are compared as
signed binary data. If the content of D110 is less than that of D210, CIO 50.01 is turned ON and
execution proceeds to the next line. If the content of D110 is not less than that of D210, the remainder
of the instruction line is skipped and execution moves to the next instruction line.
