1.7 Fill out the Capabilities
following items for
outstations only
1.7.2 How often is time synchronization required from the master: Details of when the master needs to perform a time synchronization to
ensure that the outstation clock does not drift outside of an acceptable tolerance. If the option to relate this to IIN1.4 is used, then details of
when IIN1.4 is asserted are in section 1.10.2.
● Never needs time
○ Within seconds after IIN1.4 is set
○ Periodically, fixed at ____ seconds
● Periodically, between 30 and 3600 seconds
1.7.3 Device trouble bit IIN1.6: If IIN1.6 device trouble bit is set under certain conditions, explain the possible causes.
○ Never used
● Reason for setting: Set if the IED has detected problems (Internal fail).
1.7.4 File handle time-out: If there is no activity referencing a file handle for a configurable length of time, the outstation must do an automatic
close on the file. The time-out value must be configurable up to 1 hour. When this condition occurs the outstation will send a File Transport
Status Object (group 70 var 6) using a status code value of file handle expired (0x02).
● Not applicable, files not supported
○ Fixed at ____ ms
○ Configurable, range _______ to _______ms
○ Configurable, selectable from ___,___,___ms
○ Configurable, other, describe:
○ Variable, explain:
1.7.5 Event buffer overflow behavior:
● Discard the oldest event
● Discard the newest event
○ Other, explain:
1.7.6 Event buffer organization: Explain how event buffers are arranged (per Object Group, per Class, single buffer etc) and specify the
number of events that can be buffered.
