Value / Clarification
Describe how to substitute a value.
For the attributes with FC=SV
((†/subEna, subQ, subID
and e.g. subVal) as seen in the IEC 61850 Configurator,
Machine Edition on validation automatically creates a set
of PLC Protocol Variables (PPVs) in the RX3i controller
project with extensions as shown below:
a)
†.WRITEVal (Value to
be written: Write)
b)
†.WRITECmd (Command to transfer value in
†.WRITEVal to device: Write)
c)
†.WRITERslt (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 write values to the device.
The example below shows attributes with FC=SV, used
for “write”:
IEC 61850 Configurator
The IEC 61850 variable as seen in the Configurator
dialogue:
Dev.IEDDevice.PTOV1/Mod/subVal[SV]
PLC Protocol Variables(set)
The PPV set that gets created automatically in the RX3i
controller project for the above IEC 61850 variable
a)
S8_Dev_IEDDevice.PTOV1_Mod.subEna_SV.WRITE

Describe how to substitute a value.
WRITE Operation with PPV
If the user has to write a value to such a writable data
attribute, then the following steps needs to be execute in
Application logic:
1.
Step1: Write value to be written to device in the
PPV with extension (†.WRITEVal).
