7.1.3 Input Filter
External input of GM7U selects input On/Off delay time from the range of 0-1000ms of GMWIN. Reliable system will be
established by controlling the input filter time following the environment.
1) Usage
Input signal status affects to the reliability of the system where noise occurs frequently or pulse width of input signal affects
as a crucial factor. In this case the user sets up the proper input on/off delay time, then the trouble by miss operation of input
signal may be prevented because the signal which is shorter than set up value is not adopted.
1) Only 8 points (%IX0.0.0 ~ %IX0.0.7) can be used for pulse catch input.
2) Pulse catch input contacts operate as general digital input if they are not designated as Pulse Catch Input.
2) Do not designate HSC input points as pulse catch input.
