Fast Logic Function
This function controls outputs according to the input status inside the I/O combined module without communications with the
master station. High-speed output control can be performed with this function.
Set whether to enable or disable the function for each output point from the module parameter setting window of the
engineering tool or the program. For the safety at module configuration change, the set parameter data returns to the default
value (Disable (0)) when the module is powered off. (The parameter data is not stored to the nonvolatile memory.) To keep the
set data, design a program which writes the value for the function at every module power supply on. For the program
example, refer to the following.

Overview of the fast logic function
When the fast logic function is not used
(1) An input is changed.
(2) The input status is sent.
(3) CPU module processing (program)
(4) An output instruction is received.
(5) An output is changed.
