Siemens SIMATIC NET SCALANCE XM-400 Series User Manual

Operation with C-PLUG/KEY-PLUG
The con󹪝guration stored on the C-PLUG/KEY-PLUG is displayed via the user interfaces.
If changes are made to the con󹪝guration, the device stores the con󹪝guration directly on the C-
PLUG/KEY-PLUG, if this is in the "ACCEPTED" status. The internal memory is neither read nor
written.
Response to errors
Inserting a C-PLUG/KEY-PLUG that does not contain the con󹪝guration of a compatible device
type, accidentally removing the C-PLUG/KEY-PLUG or general malfunctions of the C-PLUG/KEY-
PLUG are signaled by the diagnostics mechanisms of the device (LEDs, Web-based management
(WBM), SNMP, Command Line Interface (CLI) and PROFINET diagnostics).
The user then has the choice of either removing the C-PLUG/KEY-PLUG again or selecting the
option to reformat the C-PLUG/KEY-PLUG.
