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.
Sample program
When CIO 0.00 is ON in the following example, the floating point data in D101, D100 is compared to the
floating point data in D201, D200. If the content of D101, D100 is less than that of D201, D200, execu-
tion proceeds to the next line and CIO 50.00 is turned ON. If the content of D101, D100 is not less than
that of D201, D200, execution does not proceed to the next instruction line.
