Description
Parameters
(+) – This refers to the PPV which have †.ReadVal extensions
(x) – This refers to the PPV which are represented as array. E.g. string data types
4.4.3
Read Operations
The PPVs created as described in the section above can be monitored and used in the
application logic as normal symbolic variables.
4.4.4
Write Operations
WRITE Operation
You can perform the write operations to IED from the RX3i controller in two steps:
1.
2.
3.
The above steps can be performed in RX3i controller application using ladder logic.
For each attribute with FC=SP/SV/SE/CF, as seen in the "IEC 61850 Configurator
" dialogue, Machine Edition automatically creates a set of PPVs in the PACSystems Machine
Edition project with the extensions shown below:
a.
b.
c.
d.
WRITE Operation Example
The example below is for attributes with FC=SP, used for write operation:
System Operation
Identifier
†[DC]
†[SG]
Write the command value to the specified value variable (†.WRITEVal)
Force a rising edge to activate the operation in a specified command variable
(†.WRITECmd).
Check the result of operation is in specified result variable (†.WRITERslt).
†.WRITEVal
(Value to be written: Type – Write)
†.WRITECmd
(Command to transfer value in †.WRITEVal to device: Type – Write)
†.WRITERslt
(Result of operation – BUSY, ERROR,DONE : Type – Read)
†.ReadVal
(Value of parameter read from device: Type – Read)
