2.3.2 Replacing the I-port device – identical device type
Observe the following instructions to make sure that the con-
figuration and parameterisation of the I-port device are re-
tained in case of a replacement, e.g. service event.
1. Do not switch off the power supply to the bus node. This
ensures that the parameters for the I-port device saved in
the bus node are retained.
Do not isolate the connecting cables. The configuration of
connected devices is lost as soon as the operating voltage
supply of the bus node is interrupted.
2. Remove the bus node from the I-port device
(Dismantling/Installation Section 2.1).
3. Replace the I-port device.
To mount/dismount the I-port device, observe the
corresponding product documentation
www.festo.com
Support Portal: Enter search term, e.g. “I-port” or
“IO-Link” User documentation.
4. Mount the bus node to the I-port device (Mounting/Dis-
mounting Section 2.1).
The bus node detects the connected I-port device and
transfers the saved configuration and parameterisation to
the I-port device. Transmission of process data starts
automatically.
