OPERATE operation with PPV
If the User/Application has to write a value to such
a writable data attribute, then the following steps
needs to be execute in RX3i controller logic:
1.
Step1: Write value in PPV with 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_ctl
Val_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_ctl
Val_CO.OPERVal
3.
Step3: Provide a transition from
“0” to “1”
in the PPV with extension (†.OPERCmd) to
trigger the transfer of written value to the
IED.
e.g.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctl
Val_CO.OPERCmd
4.
Step4: Check the PPV with extension
(†.OPERSts) for status code.
e.g.
S4_SR350_DevSR350.XCBR1_Pos.Oper_ctl
Val_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_ctl
Val_CO.OPERRslt
[ WRITERslt > 0, it returns IEC 61850
AddCause
WRITERslt < 0 internal error code:
-
1: wrong parameter in (†.WRITEVal)
-2: driver not loaded
-3: write command cannot be issued
(e.g. not valid server)]
