The PPV set that gets created automatically in the RX3i project for the above IEC 61850
variable:
a.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERChk
b.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERVal
c.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERCmd
d.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERSts
e.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERRslt
f.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.ReadVal
OPERATE with PPV
If the user application needs to write a value to such a writable data attribute, the following
steps must be performed in the RX3i controller:
1.
Step1: Write value in PPV w
ith extension (†.OPERChk) as required:
0: No check
1: Interlock check
2: Synchro check
3: Interlock and Synchro check
e.g. S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERChk
2.
Step2: Write value to be written to device in the PPV with extension
(†.OPERVal).
e.g. S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERVal
3.
Step3: Provide a transition from “0” to “1” in the PPV with extension (†.OP
ERCmd)
to trigger the transfer of written value to the IED.
e.g. S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERCmd
4.
Step4: Check the PPV with extension (†.OPERSts) for status code.
e.g. S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERSts
[OPERSts returns code:
0: BUSY
1: DONE
2: ERROR ]
5.
Step5: Check the PPV with extension (†.OPERRslt) for success (1).
e.g S4_SR350_DevSR350.XCBR1_Pos.Oper_ctlVal_CO.OPERRslt
[ WRITERslt > 0, it returns IEC 61850 AddCause
WRITERslt < 0 internal error code:
-1, wrong paramete
r in (†.WRITEVal)
-2, driver not loaded
-3, write command cannot be issued (e.g. not valid server)]
Refer to Table for Add Cause, below.
