General information about IEC 61850 data modeling

The relationship between the IEC 61850 data modeling and IEC104 Slave OPC Client
is described in this section.
For each data class, there is a table giving a detailed description about the relation between
the IEC104 data and IEC 61850 data object attributes and services. The tables also
describe how the data is presented on the OPC Server name space.
The columns in the tables have the following content types:
• Name specifies the OPC item name of the attribute/service.
• Type specifies the IEC 61850 type of the attribute.
• Value/ Value range specifies the allowed values and ranges of the attribute/service.
• Mandatory/Optional specifies whether the attribute is considered as mandatory or
optional according to the IEC 61850 standard.
•
IEC104 information element specifies the IEC104 information element related to
the attribute/service.
•
OPC data types specify the OPC data type used for the OPC item.
