2.3.3 Replacing the I-port device – different device type (change)
The parameterisation of an I-port device is not automatically
restored if the device type is changed.
If the I-port device is connected to the bus node via the elec-
trical connection box, there are three distinctly different ap-
plications:
– One I-port device is connected to the electrical
connection box:
In this case, switch off the voltage supply to the bus node
and change 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.
Then switch the voltage supply back on and carry out the
required configuration and parameterisation procedures.
– Two I-port devices are connected to the electrical connec-
tion box, both devices are replaced:
In this case, switch off the voltage supply to the bus node
and change both I-port devices - as described in the previ-
ous application.
– Two I-port devices are connected to the electrical connec-
tion box, only one device is changed:
Do not switch off the voltage supply to the bus node. This
ensures that the configuration and parameterisation for
the I-port devices stored in the bus node are retained.
Observe the following instruction.
