8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
For order code options including OPC-UA communications, the OPC-UA server is always
available in the 8 Series relay. It does not need to be turned on or enabled in any way.
The 8 Series OPC-UA server internal configuration data includes the following:
• OPC-UA connection port: 4840
• Maximum number of client connections:3
• The server has the following data types:
– Double - used for Analog Values
– Boolean - used for Digital, Logic, Input and Output data
• The response time increases proportional to the number of nodes being read.
There are many OPC-UA client software applications that can be used to validate the OPC-
UA server. Some options are listed below:
• Iconics: Genesis64
• Indusoft: Web Studio
• HB-Softsolution: Comet UA Browser
• OPC UA: Sample Client
• Unified Automation: UaExpert
To view OPC-UA data, configure the OPC-UA client that will be connected to the relay, and
add the 8 Series relay as a server.
• Modeling for the following:
Events
All digital signals available generate an event with a change of value or status.
Alarms
Operate element from Protection functions generate an alarm when the status value
changes.
Commands
The Open&Close breaker and Reset commands have been implemented as Method
services.
For Virtual Inputs, these signals are directly writable from the DA view instead of Method
services.
To view the full points list, configure the OPC-UA client that will be connected to the relay,
and add the 8 Series relay as a server.
