data are blocked by the LN. Only process-related outputs on LNs related to
primary equipment are blocked. If there is an XCBR, the outputs EXC_Open
and EXC_Close are blocked.
• When the Beh of a component is set to Blocked, all control commands with a
test bit are accepted. Outputs to the process via a non-IEC 61850 link data are
blocked by the LN. In addition, the components can be blocked when their Beh
is blocked. This can be done if the component has a block input. The block
status of a component is shown as the Blk output under the Test/Function
status menu. If the Blk output is not shown, the component cannot be blocked.

Setting guidelines

There are two possible ways to place the IED in the TestMode= On" state. If, the
IED is set to normal operation (TestMode = Off), but the functions are still shown
being in the test mode, the input signal INPUT on the TESTMODE function block
might be activated in the configuration.
Forcing of binary input and output signals is only possible when the IED is in IED
test mode.

Time synchronization TIMESYNCHGEN

Application

Use time synchronization to achieve a common time base for the IEDs in a
protection and control system. This makes it possible to compare events and
disturbance data between all IEDs in the system.
Time-tagging of internal events and disturbances are an excellent help when
evaluating faults. Without time synchronization, only the events within one IED
can be compared with each other. With time synchronization, events and
disturbances within the whole network, can be compared and evaluated.
In the IED, the internal time can be synchronized from the following sources:
• BIN (Binary Minute Pulse)
• DNP
• IEC103
• SNTP
• IRIG-B
• SPA
• LON
• PPS
• IEEE 1588 (PTP)
Out of these, LON and SPA contains two types of synchronization messages:
