: If the noise filter selector switch (switch 1) on the bottom of the module (refer to Chapter 10) is turned on, the noise filter takes effect.
The off-status noise filter disables I/O response time setting.
After switching on or off the switch 1, reset the power supply of the CPU module.

combo box of PLC parameter in GX Developer. (Default: 0.2ms)
A response time setting value can be changed in GX Developer (SW6D5C-GPPW or later).
For the setting details, refer to Section 1.3.1.
3: The actual response time is 5 s delay when turning on, 10 s delay when turning off, because the hardware response time is added.
For the details of the CPU overhead time, refer to manuals for the CPU module used (Function Explanation, Program Fundamentals).
4: The module function can be changed according to the status of the function selector switch (switch 2) on the bottom of the module
(refer to Chapter 10).
ON: High-speed input
OFF: Interrupt
If the function selector switch (switch 2) setting is changed while the CPU module is in RUN, an error (error code: 2100) occurs.
5: Indicates the noise immunity when the noise filter takes effect (the noise filter selector switch (switch 1) is turned on).
6: For the setting method, refer to Section 1.3.3.
