OPC–UA Point Lists
•
Modeling for the following:
Events
All digital signals available are defined as an event source. So, the Server connection is
declared as a unique event notifier.
Alarms
The alarms are not supported.
Commands
The Open&Close breaker and Reset commands have been implemented as Method
services.
•
The OPC-UA server has implemented the following Analog, Digital, Input, Logic and
Command points, as shown in the tables.
