C) CANCEL Operation with PPV
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 attribute with (†.Cancel.ctlVal[CO]), as
seen in the IEC 61850 Configurator, Machine
Edition validation automatically creates a set of
PLC Protocol Variables (PPVs) in the RX3i controller
project with extensions as below:
a.
†.CANCELCmd (Trigger
command to
Cancel the operation to device: Write)
b.
†.CANCELSts (S
tatus of operation
–
with
code: Read)
c.
†.CANCELRslt (Result of operation –
Success
or failure with error code: Read)
d.
†.ReadVal (Actual value of parameter from
Device: Read)
These PPVs can be used to perform a CANCEL
operation in the device.
Below is an examp
le illustrating “Cancel Operation
with PPV”:
