Area of application and function of the C-PLUG
Area of application
The C-PLUG (configuration plug) that ships with the product is an exchangeable memory
medium for storing the configuration data of the device. The device can also be operated
without a C-PLUG.
This allows fast and uncomplicated replacement of a device. The C-PLUG is taken from the
previous device and inserted in the new device. The first time it is started up, the replacement
device has the same configuration as the previous device except for the MAC address set by
the vendor.
Principle
The data remains stored on the C-PLUG even when power is turned off. In terms of using the
C-PLUG, there are two ways of operating the device:
● With unwritten C-PLUG
If an empty C-PLUG (factory settings or deleted with the Clean function) is inserted, all the
configuration data of the device is saved to it automatically when the device starts up.
Changes to the configuration during operation are saved without operator intervention on
the C-PLUG if this is in the "ACCEPTED" status. This depends on how you configured your
SCALANCE device. In this mode, the internal memory is neither read nor written. This mode
is active when a C-PLUG is inserted.
● With written C-PLUG
A device with an accepted C-PLUG inserted uses the configuration data of the C-PLUG
automatically when it starts up. Acceptance is possible only when the data was written by
a compatible device type.
Response to errors
Inserting a C-PLUG that does not contain the configuration of a compatible device type,
accidentally removing the C-PLUG or general malfunctions of the C-PLUG are signaled by the
diagnostics mechanisms of the device (LEDs, Web-based management, SNMP, CLI and
PROFINET diagnostics).
4.5.2
Removing and inserting the C-PLUG (compact housing)
NOTICE
A C-PLUG may only be removed or inserted when the device is turned off.
