Treatment of spontaneous
position changes (Gen. Soft-
ware Filt./Spont. Software Filt.)
If you select the General soft-
ware filter setting, the general
settings for software filtering of
spontaneous position changes and
for position changes caused by a
switching command apply. By
selecting Spontaneous soft-
ware filter, a separate filtering
is activated for spontaneous posi-
tion changes.

The inputs and outputs as well as the setting options of the Circuit-breaker and Control function blocks are
described in the next section (see 8.2.2.3 Connection Variants of the Circuit Breaker).
Interlocking
The Interlocking function block generates the releases for switchgear interlocking protection. The actual
interlocking conditions are deposited in CFC. For more information on this, see the overreaching chapter
8.3.1 Command Checks and Switchgear Interlocking Protection.
Application and Setting Notes
Circuit Breaker
The Circuit-breaker function block in the SIPROTEC 5 device represents the physical switch device. The task of
the circuit breaker is to replicate the switch position from the status of the binary inputs.
