6.
Step6: check that the written value has
been updated in the PPV with extension
(†.ReadVal)
e.g.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctl
Val_CO.ReadVal
<additional items>
B) SELECT Operation with PPV
The control operations can executed using “SELECT
operation on PPV” for (†.Oper.ctlVal[CO]). This is
described in detail with example as below:
For the attribute with (
†.SBOw.ctlVal[CO]), as seen
in the IEC 61850 Configurator, Machine Edition
validation automatically creates a set of PLC
Protocol Variables (PPV) in the RX3i controller
project with extensions as below:
a.
†.SELECTVal (Value to be written: Write)
b.
†.SELECTCmd
(Trigger cmd to transfer
value in †.SELECTCmd to device: Write)
c.
†.SELECTSts (Result o
f operation
–
Success
or failure with error code: Read)
d.
†.SELECTRslt (Result of operation –
Success
or failure with error code: Read)
e.
†.ReadVal (Actual value of parameter
from
Device: Read)
These PPVs can be used to perform SELECT
operation to the device.
Below is an example illustrating “Select Operation
with PPV”:
IEC 61850 Configurator
The IEC 61850 variable as seen in the Configurator
dialogue:
SR350.DevSR350.XCBR1/Pos/SBOw.ctlVal[CO]
PLC Protocol Variables (set)
The PPV set that gets created automatically in the
RX3i controller project for the above IEC 61850
variable:
a.
S4_SR350_DevSR350.XCBR1_Pos.SBOw_c
tlVal_CO.SELECTVal
