Response to errors
Inserting a PLUG that does not contain the configuration of a compatible device type,
accidentally removing the PLUG/KEY-PLUG or general malfunctions of the 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 PLUG again or selecting the option to
reformat the PLUG.
Note
Incompatibility with previous versions with PLUG inserted
During the installation of a previous version of the firmware, the configuration data
can
be lost. In this case, the device starts up with the factory settings after the firmware has
been installed. In this situation, if a PLUG is inserted in the device, following the restart,
this has the status "NOT ACCEPTED" since the PLUG still has the
configuration data of
-to-date firmware. This allows you to return to the previous, more
-to-date firmware without any loss of configuration data. If the original configuration
on the PLUG is no longer required, the PLUG can be delet
ed or rewritten manually using
