Binary signal send
The status of the inputs is continuously sent in the line differential protection telegrams.
SEND_SIG_A
can be used for alarming based on the status of
SEND_SIG_1...8
. By
selecting the signal mode as "In use, alarm sel.", the sending status of the corresponding
signal affects also the activation criteria of
SEND_SIG_A
. Further, in case more than one
signal channels are selected into the alarm logic, the activation criteria can be defined
according to "Any of selected" (OR) or "All of selected" (AND).
Binary signal receive
The function receives continuous binary data within the protection telegrams from the
remote end protection relay. This received binary data status is then available as the
RECV_SIG_1...8
outputs on the local end protection relay.
RECV_SIG_A
can be
used for alarming based on the status of
RECV_SIG_1...8
. By selecting the signal
mode as "In use, alarm sel.", the received status of the corresponding signal affects the
activation criteria of
RECV_SIG_A
. Further, in case more than one signal channels are
selected into the alarm logic, the activation criteria can be defined according to "Any of
selected" (OR) or "All of selected" (AND). Each signal has also the
Pulse time 1...8
setting
that defines the minimum pulse length for
RECV_SIG_1...8
. Also, in case the
protection communication supervision detects a failure in the communication, the
RECV_SIG_1...8
outputs are not set to false sooner than the minimum pulse length
defined is first ensured for each signal.
