13.16 Station communication
13.16.1 Multiple command and transmit MultiCmd/MultiTransm
The multiple command and transmit function (MultiCmd/MultiTransm) 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.
13.17 Remote communication
13.17.1 Binary signal transfer BinSignReceive, BinSignTransm
Prepare the IED for verification of settings as outlined in section "Overview" and
section "Preparing for test" in this chapter.
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.
