OPCUA Client Pro — Full-Featured OPC UA Client for Mac
OPCUA Client Pro is a native macOS OPC UA client for industrial automation development, protocol debugging, and integration testing. Connect to remote or local OPC UA servers, explore the address space, read and write node values, monitor live data and events, call methods, read history, and manage nodes — plus run a built-in local server when you need a quick test endpoint.
KEY FEATURES
• Connect & Discovery
Connect to any opc.tcp:// endpoint with a configurable timeout. Discover servers on the network and inspect available endpoints, security policies, and security modes before you connect.
• Address Space Browser
Navigate the OPC UA address space with breadcrumb navigation, refresh, and cache control. Open nodes into Value Inspector, Subscriptions, Methods, and more from a single browse view.
• Value Inspector
Read live node values with type and array information. Write Boolean, Int32, UInt32, Double, or String values for quick commissioning and debugging.
• Real-time Subscriptions
Subscribe to node data changes with a configurable publishing interval and watch updates as they arrive.
• Event Monitor
Subscribe to server events and review event records in real time for alarms, diagnostics, and process monitoring workflows.
• Method Calls
Invoke OPC UA methods with object and method Node IDs and comma-separated input arguments — see results instantly.
• History Read
Query historical values for a node over a time range with a configurable maximum number of samples.
• Node Management
Add variables and objects under a parent node, or delete nodes when your test address space needs to change.
• Built-in Local OPC UA Server
Start a local server on a configurable port (default 4840) with optional demo nodes and methods:
- Counter, SineWave, Temperature, Message, Enabled, Pressure
- Int32Array and ByteString sample variables
- Demo methods: Add(a, b) and GetServerTime
Ideal for offline testing without an external PLC or plant server.
• Diagnostics Log
Monitor connection activity and protocol messages in the Logs view to diagnose SecureChannel, session, and communication issues quickly.
• Clean Native macOS UI
A focused SwiftUI sidebar experience covering Connect, Local Server, Browse, Value Inspector, Subscriptions, Events, Methods, History, Nodes, and Logs.
