If two I-port devices are connected to the bus node via the
CAPC-... electrical connection box, but only one device is
changed, the following instruction must be observed:
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. Replace the I-port device to be changed.
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.
The bus node detects the connected I-port device and
records the corresponding configuration data.
3. Carry out the required configuration and parameterisation
procedures.
2.3.4 Replacing the CAPC-... electrical connection box
Observe the following instructions to make sure that the
parameterisation of the I-port device is retained in case the
electrical connection box is replaced, 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 of the bus node. The
configuration of connected devices is lost as soon as the
operating voltage supply of the bus node is interrupted.
