Protocol “IEC 103” selects the IEC 60870-5-103 protocol.
IEC 103 settings Open the screen acc. to Fig. 2-3 (from Version 4.10) with MV range, Harmonics and
Counters.
MV range An additional IEC 60870-5-103 parameter determines the end range of the transmitted
measured values via the protocol.
All measured values are transferred via IEC 60870-5-103 as per-unit values in two
octets which contain the measured values itself as 12 bits and an overflow as well as
an error indication bit.
The additional parameter now decides if the measured value ranges of -4096 to +4095
correspond either
• from -120 % to +120 % or
• from -240 % to + 240 %
of the nominal values.
Harmonics The transmission of harmonic is adjustable (yes or no), from version 4.10. See chap-
ters 3.1.2.5 and 3.1.2.6.
• yes: telegram function type 130, Information number 153 (1-phase) or
154 (3-phase) is transmitted
• no: no transmission
Counters The transmission of counters is adjustable (yes or no), from version 4.10. See chapter
3.3.2.
• yes: counters acc. to table 3-6 are transmitted
• no: not transmission
Note:
The screen IEC 103 settings also is offered if Modbus is selected as protocol, but then
does not have any effect.
