Protocol Implementation extra Information for Testing (PIXIT)
Value / Clarification
Value 0: no action, execute command not
possible (status only) Value 1: an 'Operate'
service (direct control with normal security) is
executed.
Value 2: 'Select' and 'Operate' services (select
before operate with normal security) are
executed.
Value 3: an 'Operate' service (direct control
with enhanced security) is executed.
Value 4: 'SelectWithValue' and 'Operate'
services (select before operate with enhanced
security) are executed.
Command Details:
Operate command: The value is set directly to
†/Oper[CO].
Select commands are processed sequentially:
•
Select command normal security: read
from †/SBO[CO], write to †/Oper[CO].
•
Select command enhanced security: write
to †/SBOw[CO], write to †/Oper[CO].
The required command sequences are
automatically performed in the right sequence by
the driver. No further configuration steps are
necessary from user perspective in RX3i controller
logic.
In addition to this, the client Module supports
manual Select and Cancel. The client module -
according to the ctlModel of the Data Object -
executes the Select (only when ctlModel=2 or 4).
The values of ctlModel=0, 1 or 3 are treated as
negative answer of Select.
When the IEC 61850 server responds, as Select
positive, the client module stores information
about selected Data Object and in the following
command (in the following "OPERATE" operation)
executes only the Operate.
A) OPERATE Operation with PPV
The control operations can executed using
"Operate operation on PPV" for
(†.Oper.ctlVal[CO]). This is described in detail with
example as below:
For the attribute with (†.Oper.ctlVal[CO]), as seen
in the IEC 61850 Configurator, Machine Edition
