*1 When the latch range of the device for keep of the FX3 Series is changed, the latch range must be changed.
*2 Set the parameter at [Parameter] →[FX5UCPU] → [CPU Parameter] → [Memory/Device Setting] → "Option Battery Setting" in [Device/
Label Memory Area Setting].
*3 Set the interrupt setting by the parameter accordingly.
*4 The parameter is reflected at [Parameter] → [FX5UCPU] → [Module Parameter] → [High Speed I/O] → [Input Function] → [General/
Interrupt/Pulse Catch]. Also, the parameter is reflected to [Module Parameter]→[Input Response Time].
*5 The parameter is reflected at [Parameter] → [FX5UCPU] → [CPU Parameter] → [Interrupt Settings] → [Fixed Interval Setting].
