Station communication

11.14.1 Multiple command and transmit MULTICMDRCV /
MULTICMDSND
The multiple command and transmit function (MULTICMDRCV / MULTICMDSND) is only
applicable for horizontal communication.
Test of the multiple command function block and multiple transmit is recommended to be
performed in a system, that is, either in a complete delivery 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.

Binary signal transfer

Prepare the IED for verification of settings as outlined in section
settings".
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 35. 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.
