Note
:
These variables are structured variables of symbolic type. These variables can be treated as
normal symbolic variables for RX3i controller application programming purposes and all
rules of symbolic variables apply to these variables. For more information on PPV mapping ,
refer to section 4.4.2 IEC 61850 Operation and PPV Mapping.
Creating PPVs
PPVs are automatically created by Machine Edition on successful validation. This action
happens when the “IEC 61850 Configurator” dialogue is closed.
The various configuration scenarios related to this dialogue are described in section 3.6.3
Configuration Scenarios for IEC 61850 Configurator.
4.4.2
IEC 61850 Operation and PPV Mapping
This section describes the mapping between IEC 61850 attributes and PPVs, based on the
Functional constraints and operation type.
IEC 61850 Operation Table
Depending of the functional constraints, several operations can be performed. Each
operation type
except the “Direct Map” operation type has an associated variable set.
