When the On-line window in DIGSI
®
4 is opened with a double click, the operating
functions for the device appear in the left part of the window (Figure 7-35). Clicking on
Controls brings up the function selection in the right side of the window (Figure 7-
50). By double clicking on
Breaker/Switches, a dialog field is opened in which,
among other options, the option for interlocked and non-interlocked (Unlock) switching
is offered.
To switch operating resources without a check of the associated interlocking condi-
tions, mark the option
Unlock by clicking in that field, see subsection 7.4.1.
To set the switching mode for interlocked switching, the aforementioned option field
must not be marked. The marking is removed by clicking in the field again.
Further switching operations are possible until the dialog field
Breaker/Switches
is closed, or the switching mode is changed.

ment the process. For example, messages may be given to report the end of a com-
mand or provide the reason for a command denial. These messages and the associ-
ated causes are listed in Table 7-6, together with other messages for the control of de-
vice functions.
