How the Disconnection Detection Works
If the function detects disconnection, the following bits of process input data turn ON and the
I/O
Cable Disconnection (7701 hex)
device event occurs. Also, the status appears in the Pin 4/Pin 1
status indicator or Pin 2 status indicator.
Refer to
Process Input Data
of each Hub in
on page 6-2 for details on the proc-
ess input data.

Each disconnection detection bit turns OFF when the cause of the disconnection is removed.
On the other hand, each disconnection detection hold bit remains ON after the cause of the discon-
nection is removed. Refer to
Turning OFF the Disconnection Detection Hold Bits
how to turn off the bits.
The Pin 4/Pin 1 status indicator or the Pin 2 status indicator operates according to the status of
each relevant disconnection detection bit. The disconnection detection hold bits are irrelevant to in-
dicator display.
Refer to
8-4 Checking for Errors and Troubleshooting with the Device Events
tails on the device events.
Refer to
on page 3-4 for information on the indicator display.
Turning OFF the Disconnection Detection Hold Bits
Each disconnection detection hold bit remains ON after the relevant cause is removed. To turn OFF
the bits, remove the cause of the disconnection and perform either of the following operations a to
c. The operations a and b configure the relevant data in the service data through message commu-
nications from the Controller to the IO-Link device. Refer to the
NXR-series IO-Link Master Unit for
EtherNet/IP User’s Manual (Cat. No. W619)
for details on how to access the service data through
message communications. Refer to
on page 6-9 for details on the service data.
a. Execute a relevant disconnection detection hold reset
Write
01 hex: reset
in the following service data.
This turns OFF the disconnection detection hold bits.
