Binary signal transfer BinSignReceive, BinSignTransm

Prepare the IED for verification of settings as outlined in section
To perform a test of Binary signal transfer function (BinSignReceive/BinSignTransm), the
hardware (LDCM) and binary input and output signals to transfer must be configured as
required by the application.
There are two types of internal self supervision of BinSignReceive/BinSignTransm
•
The I/O-circuit board is supervised as an I/O module. For example it generates FAIL if the
board is not inserted. I/O-modules not configured are not supervised.
•
The communication is supervised and the signal COMFAIL is generated if a
communication error is detected.
Status for inputs and outputs as well as self-supervision status are available from the local
HMI under
•
Self-supervision status: Main menu/Diagnostics/Internal events
•
Status for inputs and outputs: Main menu/Test/Function status, browse to the function
group of interest.
•
Remote communication related signals: Main menu/Test/Function status/
Communication/Remote communication
Test the correct functionality by simulating different kind of faults. Also check that sent and
received data is correctly transmitted and read.
A test connection is shown in figure
. A binary input signal (BI) at End1 is configured to be
transferred through the communication link to End2. At End2 the received signal is configured
to control a binary output (BO). Check at End2 that the BI signal is received and the BO
operates.
Repeat the test for all the signals configured to be transmitted over the communication link.
