OPC Server Simulators Features

OPC Server Components

  • Advanced OPC DA HDA Server Simulator and OPC A&E Servers to cover Real-Time, Historical Simulation & Event-based communication scenarios.

Real-Time & Historical Simulation

  • OPC DA capabilities: 
  • Manage multiple OPC DA client connections.
  • Support both synchronous and asynchronous client read/write requests.
  • Simulate real-time data values for a set of predefined tags with configurable access rights.

  • OPC HDA capabilities: 
  • Manage multiple OPC HDA client connections. 
  • Support synchronous and asynchronous read and update requests. 
  • Simulate historical raw and processed data for selected tags. 

  • OPC A&E capabilities: 
  • Manage multiple OPC A&E client connections and event subscriptions. 
  • Simulate real-time alarms and events. 
  • Handle event condition management (enable/disable, activate/deactivate, acknowledge).

Configuration

  • Configure your own tags and customize the OPC Server address space
  • Specify your OPC data set simply by using CSV files
