How it works
Operating mode
In terms of the C-PLUG, there are three modes for the device:
• Without C-PLUG
The device stores the configuration in internal memory.
This mode is active if no C-PLUG is inserted.
• With unwritten C-PLUG
If an unwritten C-PLUG (factory status or deleted with Clean function) is used, the local
configuration already existing on the device is automatically stored on the inserted C-PLUG
during startup.
This mode is active as soon as an unwritten C-PLUG is inserted.
• With written C-PLUG
A device with a written and accepted C-PLUG uses the configuration data of the C-PLUG
automatically when it starts up. The requirement for acceptance is that the data was written
by a compatible device type.
If there is configuration data in the internal memory of the device this is overwritten.
This mode is active as soon as a written C-PLUG is inserted.
Operation with C-PLUG
The configuration stored on the C-PLUG is displayed over the user interfaces.
If changes are made to the configuration, the device stores the configuration directly on the
C-PLUG, if this is in the "ACCEPTED" status and in internal memory.
Response to errors
Inserting a C-PLUG that does not contain the configuration of a compatible device type and
inadvertently removing the C-PLUG, or general malfunctions of the C-PLUG are indicated by the
diagnostic mechanisms of the device.
• Fault LED
• Web Based Management (WBM)
• SNMP
• Command Line Interface (CLI)
• PROFINET diagnostics
The user then has the choice of either removing the C-PLUG again or selecting the option to
reformat the C-PLUG.
