Other IEC 60870-5-103 data
3.4.1
Changing parameter setting group
The IED supports remote changing of the used parameter setting group. The four
possible setting groups in the IED are coded as objects Characteristic 1…
Characteristic 4 using standard information numbers 23…26.
On the IED's native IEC 61850 model level the parameter setting group change
object is also a setting parameter in itself, not a process object as is assumed in the
IEC 60870-5-103 standard. Only process object updates get accurate time stamps
from the IED system level. Consequence is that Class 1 event updates concerning
changes in objects Characteristic 1…Characteristic 4 do not contain an accurate
time stamp but rather a time stamp from when the change was noticed by the IEC
60870-5-103 stack.
In a normal case, any parameter setting change in the IED requires that the client
first reserves the parameter setting rights, then changes the setting and finally
stores the change. An exception to this is the
Parameter setting group change
parameter. Writing remotely to this parameter automatically includes reservation
and storing.
3.4.2
Device identification
3.4.2.1
Device function type
The IEC 60870-5-103 standard requires that an IED is identified as a certain
Device type. The standard has only the following single functional device types:
•
128 distance protection
•
160 overcurrent protection device
•
176 transformer differential protection
•
192 line differential protection
Since RE_615 is always a multifunctional IED, the Device type is set to the private
function type value 9 as default. However, if this definition would cause
incompatibility with some client systems, the user can freely change the definition
through the
DevFunType n
parameter located via LHMI path
Configuration/
Communication/IEC 60870-5-103/DevFunType n
.
3.4.2.2
Device identification code
The device identification information for the IED is defined as follows:
