21.3.5 Operation principle
Set the IED in test mode by
• configuration, activating the input SIGNAL on the function block TESTMODE.
• setting
While the IED is in test mode, the output ACTIVE of the function block TESTMODE is activated. The
other outputs of the function block TESTMODE shows the cause of the "Test mode:
— input from configuration (OUTPUT signal is activated) or setting from local HMI (SETTING signal
is activated).
While the IED is in test mode, the yellow Pickup LED will flash and all functions can be blocked
depending on the configuration of the testmode component. Any function can be unblocked
individually regarding functionality and event signalling.
The functions will be blocked next time if the testmode component is configured to block
components upon puting the IED into testmode.
The blocking of a function concerns all output signals from the actual function, so no outputs will
be activated.
The TESTMODE function block might be used to automatically block functions when a test handle
is inserted in a test switch. A contact in the test switch (RTXP24 contact 29-30) or an FT switch
finger can supply a binary input which in turn is configured to the TESTMODE function block.
Each of the functions includes the blocking from the TESTMODE function block.
The functions can also be blocked from sending events over IEC 61850 station bus to prevent
filling station and SCADA databases with test events, for example during a commissioning or
maintenance test.
21.4 IED identifiers
21.4.1 Functionality
IED identifiers (TERMINALID) function allows the user to identify the individual IED in the system,
not only in the substation, but in a whole region or a country.
Technical manual
TestMode to Enabled in the local HMI, under Main menu/TEST/IED test mode.
If the IED is restarted while set to IED testmode by a binary input all functions will
be temporarily unblocked during startup, which might cause unwanted operations.
Use only characters A-Z, a-z and 0-9 in station, object and unit names.
