Functional Constraints
The little icons provide information. "DO" is for Data Object. Within the DO, there
may be multiple levels of data. Down at the Data Attribute level, the functional
constraint of the Data Attribute is shown in the icon, e.g. "CO" for Control, "ST"
for Status Information, and "CF" for Configuration.
IEC 61850 MMS Read
For data that the ProSoft gateway needs to read from the IED, simply drag and
drop the Data Attributes from the tree view on the left to the right-hand side of the
IEC 61850 Mapping Tool window.
If you want to choose several Data Attributes at the same time, you can drag and
drop a Data Object (DO) at a higher level, rather than each individual Data
Attribute.
The gateway processes its list of configured IEDs in order, one at a time, based
upon its MMS Scan Delay timer. Each MMS Read command will be sent on the
interval provided by the MMS Scan Delay parameter.
The Data Attribute data is put into the ProSoft gateway
’s internal tag database.
