1.4.2 Extension I/O
For extension I/O, selection can be made from PIO (NPN or PNP) and six types of fieldbus
(CC-Link, DeviceNet, FROFIBUS-DP, EtherNet/IP, EtherCAT or PROFINET-IO) to be equipped
with.

Caution:

If a non-contact circuit is connected externally, malfunction may result from
leakage current. Use a circuit in which leakage current in a OFF state does not
exceed 1mA.
 At the default settings, the system recognizes the ON/OFF durations of input
signals if they are continuous approx. 4 msec or longer. The ON/OFF duration
settings can also be changed using I/O parameter No. 20 (input filtering
frequency).
