Function
Devices with a CLP slot support the following operating modes:
•
Without CLP
The device saves the configuration data in the internal memory. This mode is active
when no CLP is inserted.
• With CLP
In the startup phase:
– When an empty CLP (delivery state) is inserted into the device, the device
automatically backs up the configuration data on the CLP during startup. After
that, it behaves like a CLP with data.
– When a CLP with data is plugged into a device, the device automatically adopts
the configuration of the CLP during the startup phase. The prerequisite for this is
that the configuration data was written by a compatible device type.
One exception to this can be the IP configuration if it is set using DHCP and the
DHCP server has not been reconfigured accordingly. Reconfiguration is necessary
if you use functions based on MAC addresses.
– If the CLP contains a license, additional functions are also enabled.
Note
If the device was configured at some time with a CLP license, the device can no
longer be used without this CLP. To be able to use the device again, reset the
device to the factory settings.
During operation:
– During operation, changes to the configuration are saved on the CLP and in the
internal memory.
– The configuration data of the device is stored in a secured memory area of the
CLP. This secured memory area can only be accessed via the authentication of the
Siemens device.
– The device checks whether a CLP is inserted at one second intervals. If the device
detects that the CLP has been removed, it restarts automatically.
NOTICE
Operating risk - Danger of data loss
Only pull and plug the CLP when the device is de-energized.
– The device signals deviations from normal operation of the CLP (e.g., incompatible
data, incorrect operation or malfunctions) via the existing diagnostics mechanisms
(e.g., LEDs or user interfaces).
The procedure for inserting and removing the CLP can be found in the section
"Replacing a CLP (Page 62)".
