OPCUA Rules

OPC UA Protocol (OPC Unified Architecture) is a communication protocol designed for industrial automation, enabling interoperability between different devices and systems.

Use OPCUA Rules to configure communication between the NexusIM gateway and southbound devices through the OPC UA protocol.

Go to Sensor Data > Devices and Rules > OPCUA Rules to view and configure OPCUA rules.

OPCUA Setting

  1. Preview the current value collected from the southbound device for this rule.
  2. Edit the added rule.
  3. Delete the added rule.
  4. Add a new rule.
  5. Export or import the rules configuration as a CSV template file. This is useful for configuration backups and batch operations.
