coding of double-pole objects. The possible values are “00” for None, “01” for OK
and “11” for Alarm.
In case of a two-position “OK-Alarm” LED, the
LED area 2
data can be configured
to show normal Off/On DPI-data using the double-point extended value to single-
point value conversion. This means that the actual DPI LED values are converted as
00-to-10, 01-to-01, (10-to-10), 11-to-10. Thus, the LED state OK (“01”) is shown as
value “01” (Off) and state Alarm (“11”) as value “10” (On).

The two IEC 60870-5-103 LED areas are updated in parallel. LEDs can be configured
individually. The most suitable IEC 60870-5-103 LED data object for each case can
be chosen.
3.3.3
Analog events
Some selected analog values in the relay are available as so called ASDU 4 or TypeID
4 analog Class 1 events. Depending on the supported applications, the values may
include the registered maximum current and voltage values during a fault and fault
locator registrations. For example, also tap changer position values can be obtained
through TypeID 4.
There is no internal prioritization between TypeID 4 and indication
events in the IED. Enabling events, for example for fault record
function, can cause considerable delay in indication event reporting.
It should be carefully considered which TypeID 4 data is included in
event reporting by setting “TypeId4 in use” in the Communication
Management tool.
Fault record data can be configured to be generated only at operation
situations. At operation, the circuit breaker opens, and after that, no
more protection or indication events are generated by the IED. In such
case, the trailing fault record data does not overload the event buffer.
3.3.3.1
Configuring of analog events
The selection of available TypeID 4 values can be seen in the measurand list of the
Communication Management tool in PCM600 with other analog values of the relay.
The object state column shows if a measurand is a TypeID 4 object, either in use or not.
