LT4000 Series
From the [Project] menu, point to [System Settings] and click [I/O Driver]. Specify the [Standard Input]. Input filtering time range is from 0 milliseconds to 20 milliseconds in 0.5 millisecond unit.
A setting of 0 milliseconds disables the digital input filter.
When CH1 to CH4 are all set to "Standard", [Type] can be set to "Bit" or "Word".
When either Input or Output [Type] is set to "Integer" in the LT3000 Series, Special I/O cannot be selected in CH1 to CH4. When setting Special I/O, set all [Type] to "Bit". In the LT4000 Series, when the [Type] is set to [Integer] for input only, you can set special I/O for output.
Be careful when changing [Type] while I/O is already allocated. I/O mapping may be canceled, or errors may occur when saving or transferring.
