7 IEC 61850 PROTOCOL
Description(cont.)
Additional Items:
The following control models are available only for Pos
controllable attribute of XCBR LN. For the rest of
controllable objects only direct-with-normal-security model
is permitted.
Behaviour of DUT in case of control models direct-with-
enhanced-security or sbo-with-enhanced-security
7 PIXIT for Time and time synchronisation model
Description
What quality bits are supported
What is the behaviour when the time synchronization
signal/messages are lost
When is the quality bit "Clock failure" set?
When is the quality bit "Clock not synchronised" set?
8 PIXIT for File transfer model
Description
What is structure of files and directories?

sbo-with-enhanced-security
After reception of "Operate" service the DUT will check
whether the operation has been succesfully done. The
timeout DUT internally checks for operation realisation is
fixed at 30 seconds. If this timeout elapses and the
operation has not been finished the DUT will send negative
Command Termination service to the client. If the operation
finishes within the 30 seconds timeout the DUT will send
positive Command Termination service to the client.
In case of direct-with-enhanced-security when the DUT is
waiting for operation result new "Operate" requests from
any client will be rejected until the pending operation
finilized sucessfully or the 30 seconds timeout elapses.
Value / Clarification
N LeapSecondsKnown
Y ClockFailure
Y ClockNotSynchronized
Internal clock is used.
It is set when SNTP packet with LI field (Leap Indicator)
with both bits set to ON is received.
It is set when the communication is lost with the time
server. The timeout for setting this bit is 1 minute for
unicast mode, 5 minutes for anycast mode and up to 18
minutes for broadcast mode.
After startup the device has not set this quality bit even if
the time server is not present or not working. The bit will
be set when the corresponding timeout elapses.
Value / Clarification
The main directory for files is "/LD/XXXLD/" where XXXLD
is the Logical Device name.
COMTRADE files are located in "/LD/XXXLD/
COMTRADE/" directory. All other files are in "/LD/XXXLD/"
directory.
The device will retrieve the content and/or definition of
files when the client's request contains the filename with
full path or only the filename withouth path. Relative paths
like "/XXXLD/file1" or "COMTRADE/file1" are not allowed
and they will be replied by the server with error code "file-
non-existing".
