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 the IEDs are multifunctional, 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 definition can be changed through the
DevFunType n
parameter.
The value in
DevFunType n
is automatically assigned to all IEC 60870-5-103 data
points that have their function type defined as 0. The user has to assure that no similar
IEC 60870-5-103 point definitions already exist with the same function type and
information number.
3.4.2.2
Device identification code
The device identification information for the IED consists of three parts.
•
Compatibility level (COL) = 2
•
Eight character ASCII ID string
•
Internal code = 4 octets
The ASCII string consists of eight characters, for example, 620FE201.
6 2 0 F E 2 0 1
6 1 5 T E 0 8_
Series (615, 610, 620..)
Device type (REF, RET, REM..)
Region (E=IEC, A=ANSI)
Variant (up to 3 digit number,
padding space (_) characters 20H
added to the end if needed)
