Compact Operating Instructions, 05/2016, A5E02661178-10
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).
3.7.2
Removal and insertion of the C-PLUG (rack devices)
NOTICE
A C-PLUG may only be removed or inserted when the device is turned off.
Position of the C-PLUG with rack devices
With rack devices, the slot is below a cover on the right-hand side of
the housing. After undoing the screw (screw head Torx T10), the
cover plate can be removed and the slot is accessible.
