-Software error messages
-Communication ports failures
-TCP/IP channels open and close operations, failures
9.2 Events archiving
Console log files, events and errors are collected and archived in the form of
text files and are physically saved to device’s flash memory. By default, each
log file have size at 5 MB. Events log will be updated only if any events occur.
If no events are detected, nothing will be written to events text file.
Device have 3 opportunity to download data files to your personal computer.
a) Use Web browser. Logs are opened and viewable in text format on the

•Object.Addr ν– Object’s downlink address
•61850 v – 61850 address (loaded from device’s XML file)
•Object.Addr ^ – Object’s uplink address
It is possible to send the same object to control centre with different

and different uplink addresses.
•Comment – comments of devices
•DB1 %Fs – Deadband (% of full scale). If the value has changed less
than the deadband then it is not spontaneously transferred.
•Raw Min, Raw Max – Minimum and maximum raw values of analog

Crit.Min %Fs; Crit.Max %Fs – Minimum and maximum values in %
from the full scale of analog measurements on which GW6e initializes
communication (Fig. 10.5.1). If Crit. Max and Crit. Min do not have
values, DB1 and DB2 are in use. If Crit. Max and Crit. Min have the
value ‘zero’, only DeadB1 is in use. If the analog measurement value is
between Crit. Min and Crit. Max, DB2 is in use. If the analog
measurement value is out of limits, DB1 is in use.
On Ev. Nr; Off Ev. Nr – Corresponding event number used in SPA-bus
•Ch. Nr. – Channel nr. for SPA-bus communication protocol
•NoFlags – If set to Yes, removes Invalid and Not Topical flags from
