Reference
I/O function This function enables you to set pin 4 and pin 2 of
each port to input or output, depending on the devices
connected to the Digital I/O Variable Hub. I/O Varia-

I/O cable dis-
connection de-
tection This function detects disconnection of I/O cables from
the Digital I/O Hub. You can enable or disable the dis-
connection detection. All mod-

I/O cable short-
circuit detection This function detects short-circuits in I/O cables for the
Digital I/O Hub. When a short-circuit occurs, the Hub
turns off the power supply to the sensor and the digital
output to protect the internal circuit. All mod-

All hold bits re-
set This function resets all hold bits for detection of dis-
connection, short-circuit, and power supply voltage
drop that occur to the Digital I/O Hub. All mod-

Voltage drop
detection for
Unit/input pow-
er supply This function monitors the Unit/input power supply
voltage fed to the Digital I/O Hub, and detects voltage
drop when the voltage decreases below the monitored
voltage. All mod-

Voltage drop
detection for
output power
supply This function monitors the output power supply volt-
age fed to the Digital I/O Variable Hub, and detects
voltage drop when the voltage decreases below the
monitored voltage. I/O Varia-

Digital input fil-
ter This function eliminates the chattering or the noises
from input signals to the Digital I/O Hub. When the in-
put data changes without stabilization of the state of
the contact point due to chattering and noise, this
function prevents changes in data and stabilizes it. All mod-

put setting This function performs the preset output operation
when the Digital I/O Variable Hub cannot receive out-
put data from the IO-Link Master Unit. I/O Varia-

Monitoring total
power-ON time This function records the time period during which the
Unit/input power is supplied to the Digital I/O Hub, and
displays the period as the operating hours of the Hub. All mod-
