Precautions
• The operation of DIFD(014) will not be consistent if the same function block instance is executed
more than once in the same cycle.
• An subroutine will not be executed while the input condition for the subroutine is OFF. Caution is thus
required when using DIFD(014) in a function block definition. For details, refer to information on
SBS(091).
Sample program
When CIO 0.00 goes from ON to OFF in the following example, CIO 100.00 is turned ON for one cycle.
