Confirmation ID Meaning Description
Switching Authority Release for switching
authority Local The confirmation ID is queried only for devices
without a key switch; otherwise it is replaced with
the key switch position.
The confirmation IDs are preset with the following values:
•
Set/operate 222222
•
Control (process, interlocked) 333333
•
Control (not-interlocked) 444444
•
Switching authority local 666666
If you have configured a device with key switches, the confirmation IDs for non-interlocked switching and
switching authority are not displayed or editable in DIGSI; the function is handled by the position of the key
switch.
To increase security, change these codes with DIGSI.
Switching Mode (Interlocked/Non-Interlocked)
The switching mode determines whether or not the switchgear interlocking that has been configured in the
CFC is checked before the command is output.
You can change the switching mode with the key switch S1 (interlocking off/normal). For devices without a
key switch, you can change the switching mode with a corresponding menu item on the display (after
entering a confirmation ID). You can also set the switching mode for switching commands from the sources
DIGSI, station or remote.
!
DANGER
If the switching mode = non-interlocked, the switchgear interlocking protection is shut off
Erroneous switching operations can lead to severe or fatal injuries.
²
Ensure manually that all checks have been implemented.
In addition, you can set the switching mode directly with a binary input or CFC. Use the General function
block (see next figure).
