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 "Preparing the IED to verify 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

59. 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.
