Precautions
• The operation of DIFU(013) depends on the execution condition for the instruction itself as well as the
execution condition for the program section when it is programmed in an interlocked program section,
a jumped program section, or a subroutine.
• An subroutine will not be executed while the input condition for the subroutine is OFF. Caution is thus
required when using DIFU(013) in a function block definition. For details, refer to information on
SBS(091).
• The operation of DIFU(013) will not be consistent if the same subroutine is executed more than once
in the same cycle.
Sample program
When CIO 0.00 goes from ON to OFF in the following example, CIO 100.00 is turned ON for one cycle.
