may be overwritten. Replacing the log texts is now completed.
• 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.
