1.5 Replacement of the bus node
Easy replacement using memory card
The memo ry card is used as a carrier of co nfi guration data,
e.g. of the fieldbus device name, i.e. of the PROFI N ET I/O
device name. Thus, a bus node can be conveniently replaced.
Note
Check the start behaviour of the CPX terminal
before replacing the bus node.
If the Modify LED (M) lights up or flashes permanently
after the system start, “System start with saved paramet-
erisation and saved CPX expansion” is set or “F orce ” is
active.
Fo r CPX terminals with a permanently lit or flashing M-L ED,
the parameterisation at replacement of the bus node or
CPX terminal during servicing is not automatically created
by the higher-level system.
In this case, verify which settings are required before re-
placement and resto re these settings after replacement.
Caution
Risk of malfunctions or damage.
Inserting or removing the memory card while the power
supply is switched on can result in malfunctions of or dam-
age to the memory card.
•
Disconnect the power supply before you inser t or re-
move the memory card.
