system as an acceptance test (FAT/SAT) or as parts of that system, because the
command function blocks are connected in a delivery-specific way between bays
and the station level and transmit.
Command and transmit function blocks included in the operation of different built-
in functions must be tested at the same time as their corresponding functions.

Prepare the IED for verification of settings as outlined in section
To perform a test of the binary signal transfer functions, 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 the binary signal transfer:
•
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.
