4.
Step4: Check the PPV with extension (†.SELECTRslt) for success (
1).
e.g S4_SR350_DevSR350.XCBR1_Pos.SBOw_ctlVal_CO.SELECTRslt
[ SELECTRslt > 0, it returns IEC 61850 AddCause
SELECTRslt < 0 internal error code:
-1, wrong parame
ter in (†.SELECTVal)
-2, driver not loaded
-3, write command cannot be issued (e.g. not valid server)]
Refer to Table for Add Cause, below
5.
Step5: check that the written value has been updated in the PPV with extension
(†.ReadVal)
e.g. S4_SR350_DevSR350.XCBR1_Pos.SBOw_ctlVal_CO.ReadVal
CANCEL Operation
The control operations can executed using “CANCEL operation on PPV” for
(†.Cancel.ctlVal[CO]). This is described in detail with example as below:
For the attri
bute with (†.Cancel.ctlVal[CO]), as seen in the IEC 61850 Configurator, Machine
Edition on validation automatically creates a set of PPVs in the project with extensions as
below:
a.
†.CANCELCmd (Trigger command to Cancel the operation to device: Type
- Write)
b.
†.CANCELSts (Status of operation –
with code: Type - Read)
c.
†.CANCELRslt (Result of operation –
Success or failure with error code: Type - Read)
d.
†.ReadVal (Actual value of parameter from Device: Type

These PPVs can be used to perform CANCEL operation to the device.
