2.2 Command processing

6MD665 Manual
C53000-G1876-C103-3
to issue a closing command, the command will be refused, with the operating
message "scheduled condition equals actual condition". Switchgear in the fault posi-
tion are not interlocked by software means.
De-interlockings
De-interlockings can be bypassed to perform switching operations. This is either done
internally by adding a bypass code to the command, or globally by so-called switching
modes.
• SC=LOCAL
– The switching modes "interlocked (latched)" or "non-interlocked (unlatched)" can
be set via the key switch. The position "Interlocking OFF" corresponds to non-
interlocked switching and serves the special purpose of unlocking the standard
interlocks.
• REMOTE and DIGSI
®
– Commands issued by SICAM
®
or DIGSI
®
are unlocked via global switching mode
REMOTE. For de-interlocking a separate job must be issued. De-interlocking is
done in each case only for one switch action and only for commands of the same
origin source.
– Job: command to object "Switching mode REMOTE", ON
– Job: switching command to "switchgear"
• Derived command via CFC (automatic command, SC=Auto SICAM):
– Behaviour configured in the CFC block ("BOOL to command").

Process Data
During the processing of the commands, independent of the further message routing
and processing, command and process feedback information are sent to the message
processing centre. These messages contain information on the cause. With the cor-
responding allocation (configuration) these messages are entered in the event list,
thus serving as a report.
