Operation of DIFU(013)
When CIO 000000 goes from OFF to ON in the following example,
CIO 001000 is turned ON for one cycle.
001000
Operation of DIFD(014)
When CIO 000000 goes from ON to OFF in the following example,
CIO 001000 is turned ON for one cycle.

001000
Note Observe the following precaution when using DIFU(013) in a function
block definition.
The operation of DIFU(013) will not be consistent if the same function block
instance is executed more than once in the same cycle.
An instance will not be executed while EN is OFF. Caution is thus required
when using DIFU(013) in a function block definition. For details, refer to infor-
mation on restrictions on using ladder programming instructions in the CX-
Programmer Operation Manual: Function Blocks.
Observe the following precaution when using DIFU(013) in a subroutine.
The operation of DIFU(013) will not be consistent if the same subroutine 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 DIFU(013) in a function block def-
inition. For details, refer to information on SBS(091).
SET turns the operand bit ON when the execution condition is ON.
RSET turns the operand bit OFF when the execution condition is ON.
