•
New standard password
The devices will be delivered with a
default password “siemens”
defined for the SIMEAS
R system. This password will also be used under OSCOP P as a standard password.
The older default password “kennwort” and user-defined passwords are still valid.
•
Memory size for the function "Voltage dips" (V23.16 and V30.16 only)
The memory size for the Voltage dips function must not be set smaller than 10 MB.
•
Logical triggers
a) In the OSCOP Transfer module, "logical" appears as the source of triggering if a logical
trigger triggered a fault record. This entry does not provide any information about the num-
ber of the logical trigger.
b) Do not parameterize more than two logical triggers. The combination of 8 logical triggers
mentioned in the manuals SIMEAS R (E50417-B1076-C209-A4) chapter 1.4.5.7 and
OSCOP P (E50417-H1000-C170-A2) chapter 6.12.4 is not correct.
•
SIMEAS R in a Network
The device can be used in a network if you meet the following preconditions
a)
No port scans
are used in the network.
b) The network is protected against
attacks of hackers
.
c) The network is not operated with the „
IP Security Protocol
“. This protocol may be acti-
vated in networks running under Windows 2000 or Windows XP.
•
Trigger source f/P recorder with high averaging time
If a very high averaging time (e.g. 250 cycles) is set in the f/P recorder, transient measured
values are not visible in the fault record because of the averaging. For this reason the tran-
sients cannot be detected as the trigger source in the f/P fault record.
•
Trigger source (+dM/dt, MAX) for f/P recorder
If the response thresholds in the frequency-power recorder for the MAX trigger and the
+dM/dt trigger are chosen, for example, to meet the conditions for both types of trigger after
a sudden change in current, MAX trigger may be indicated as the source of triggering
although the record was triggered by +dM/dt trigger.
•
Trigger for positive-/negative-sequence system
The analog fault recorder can only be triggered for positive-/negative-sequence system, if the
mean value recorder f,sym is activated.
