Version Changes
COMM1 Bug fixing in the COURIER protocol:
Upon activation of COURIER protocol a warm restart of
the device was initiated.
Bug fixing:
●
IEC 60870-5-101: Support of the 7-byte time tag
length has been corrected: (003 198) COMM1:
Time tag length = 7 Byte
●
IEC 60870-5-101: Transmission of negative cyclic
measured values has been corrected.
●
IEC 60870-5-101: Acknowledgment of the general
scan command has been corrected.
●
IEC 60870-5-101: Signals in the general scan are
now transmitted correctly without a time tag.
●
IEC 60870-5-101: Command rejections issued
internally by the protection device (between the
processor module and communication module)
are no longer signaled by the communication
interface.
●
IEC 60870-5-101: Commands are now transmitted
correctly, even when the ASDU address length is
2 byte: (003 193) COMM1: Address length
ASDU = 2 byte
FT_RC The recording duration for binary tracks is now limited
to 1 minute in order to prevent recording of endless
events.
MAIN Priority control of clock synchronization is now settable.
Positive- and negative-sequence currents from all ends
are now continuously calculated and displayed as
measured operating data (primary and per-unit values).
The functionality for the current summation was
extended. Besides summation of current values from 2
ends it is now also possible to sum current values from
3 ends and to subtract current values from 2 ends.
OL_RC, FT_RC Overload and fault recording now have a joint and
complete list of possible entries (merged list of all
previous signals).
In practice it became apparent that limitations with
regard to possible entries in both recording memories
would bring no advantages but make analyzing more
difficult, as both recording memories could be open at
the same time (e.g. a thermal overload situation could
lead to a loss of insulation which would cause a fault).
