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
