The following table shows the related special data registers. Note that Y000, Y001, Y002, and Y003 are
devices that determine the pulse output destinations.
*1. Devices related to Y003 (pulse output destination) are only valid if two FX3U-2HSY-ADP adapters are
connected to the FX3U PLC.
*2. This function is valid if Ver.1.30 or later is used.
However, to specify the user interrupt input command, Ver.2.20 or later should be used.
*3. This function is valid if Ver.2.20 or later is used.
