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.
[sc_ivsrou, 1, en_US]
Set the binary input used for signaling-voltage supervision within one input/output module using the setting
option (see the following figure). This binary input monitors the presence of the signaling voltage. If the
signaling voltage fails, this sets the quality attribute for all other binary inputs of the parameterized input/
output module to
invalid
. The signal status of each of these binary inputs is frozen with its last valid value
prior to the occurrence of the fault. The quality attribute of the binary inputs for other input/output modules
are not taken into consideration by this.
If the signaling voltage again exceeds the binary threshold, the quality attribute of the binary inputs is reset to
valid
.
