OPCUA Enable
Range: Disabled, Enabled
Default: Disabled
The OPCUA Enable setting is only for a relay with a communications Order Code 4.
In this case only, the OPC-UA and the IEC61850 protocol do not run simultaneously. If
IEC61850 is running by default but it is desired to use OPC-UA instead, the user must put
the OPCUA Enable setting to Enabled. Then, the relay must be rebooted. This will run the
OPC-UA instead of the IEC61850.
In SR350 with communications Order Code 5, this setting is not visible and both protocols
run simultaneously.
The servers internal configuration data are the following:
• OPC-UA connection port is 4842Maximum number of sessions per server is 2
• The server has the following data types:
– Double - used for Analog Values
– Boolean - used for Digital, Logic, Input and Output data
• The server guarantees the reading of 60 nodes. If the number of nodes is bigger than
this value, the response time increases proportionally to the number of nodes.
• 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.
