Bug fixing:
●
In versions -606 to -610 inrush signaling from all
three measuring systems was suppressed when
harmonic blocking in measuring system 1 was
triggered. This was not accompanied by tripping.
Nevertheless there was the possibility of an
overreaction (tripping) when an inrush condition
was not recognized by one measuring system
with the operating mode set to “Not phase-
selective” and in an other measuring system the
second harmonic component reached a value of
approximately between 70% and 130% of the
fundamental.

Bug fixing:
●
The cause for a break in the client-server
communications link after approximately 49 days
for about 20 minutes has been removed. GOOSE
and GSSE were not affected by this break in the
client-server communications link.
●
If communication was interrupted during control
access via the Ethernet interface using the
operating program MiCOM S1, renewed control
access was only possible after a warm restart of
the protection and control unit.
COMM1 The upgraded communications software 3.18 is now
implemented. Various small bugs have been fixed in
communication protocols per IEC 60870-5-101 and
MODBUS.
