Signaling-Voltage Supervision

8.3.1.1

Overview of Functions

Signaling-voltage supervision is used to evaluate the validity of binary signals connected to the SIPROTEC
device via binary inputs. For this purpose, one binary input is used to monitor the signaling voltage. If the
signaling voltage fails, the associated binary signals are marked as invalid and a Signaling-voltage malfunc-
tion indication is issued.
Several signaling-voltage supervision groups can be created in one SIPROTEC device. Each of these groups
monitors an adjustable area with binary inputs.
8.3.1.2

Structure of the Function

The Signaling-voltage supervision function group contains, besides the general functionality, one preinstan-
tiated Supervision group stage. The Supervision group stage can be instantiated in DIGSI 5 multiple times.

Function Description

You can instantiate the Signaling-voltage supervision function group in DIGSI from the global library. It
contains 1 pre-instantiated Supervision group function block (see the following figure). You can instantiate a
maximum of 25 supervision groups.
[sc_ivslib, 1, en_US]
Following the instantiation of the function group in the DIGSI project tree, it appears in the information
routing of DIGSI (see the following figure). The status indications of the supervision groups can be routed
here, for example, to existing binary outputs and/or logs.
