Input Off Delay Function - Mitsubishi Electric NZ2GF12A4-16D User Manual

Input OFF Delay Function

This function turns off an X signal after a predetermined time passed from when an actual input becomes off from on.
With the input OFF delay function, even an input whose ON time is extremely short can be surely recognized on a program.
When an external input device is replaced with a sensitive one, users can use their previous program by only adjusting the
delay time.
Set whether to enable or disable the function and set the delay time for each input point from the module parameter setting
window of the engineering tool or the program.
Ex.
A short period of ON time can be surely recognized by setting the delay time longer than the period of the link scan time.

When the ON time of the target input signal is less than 100s, the module cannot recognize ON of the input and the input
OFF delay function may not be performed.

• The delay time does not include the hardware response time.
• The accuracy of the delay time is 0 to 400s.
