Precautions
• Some time will be required to complete BCNT(067) if a large number of words is specified. Even if an
interrupt occurs, execution of this instruction will not be interrupted and execution of the interrupt task
will be started after execution of BCNT(067) has been completed. One BCNT(067) instruction can
be replaced with two BCNT(067) instructions to help avoid this problem.
Sample Program
When CIO 0.00 is ON in the following example, BCNT(067) counts the total number of ON bits in the 10
words from CIO 100 through CIO 109 and writes the result to D100.
