Version Changes
IEC The Originator Category information is now extensively
supported for control commands.
Bug fixing:
●
If single-pole signals of function group SIG_1 were
active during device startup, this could lead to an
aborted initialization of the Ethernet
communication module.
●
During the process of connection with clients that
use the “IntegrityPeriod” option, sporadically the
MMS communication of the Ethernet
communication module would crash without an
internal monitoring response to re-establish the
functionality. (GOOSE messaging and other
communication tasks were not affected.)
●
If clients did connect to the device immediately
after completion of Ethernet communication
module startup, this could lead to the temporary
erroneous reporting of default values for the
external device status (DEVxx) and of the single-
pole signals (SIG_1).
●
Reports of events could get lost if too many state
changes occurred in a short period of time,
especially during secondary injection testing.
●
Events that occured after a communication link
had been interrupted and before this interruption
had been detected by the server, were not sent
as “Buffered reports” after the connection was re-
established.
GOOSE The GOOSE Time Allowed to Live (TAL) supervision is
enhanced with respect to simultaneous state changes
of multiple GOOSE messages.
PC, COMM2
Bug fixing:
●
If clients did connect to the device immediately
after startup of the Ethernet communication
module, the initialization of the second internal
communication interface could remain
incomplete. As a consequence, access by the
operating program via the COMM2 interface or by
tunneling was not possible in this case.
P634
‑310
‑409/410
‑650
Release: 2013-07-12
Hardware
The P634 is now fitted with an improved processor
module.
The previously optional DSP coprocessor is no longer
needed.
The current transformer supervision (CTS) function is
generally available.
