OPC Server Simulators - Free Product

OPC Server Simulators is a free suite of software tools designed to test, validate, and troubleshoot OPC client applications without requiring a connection to live industrial equipment. The simulators provide simulated real-time data, alarms and events, and raw and processed historical data, enabling developers, end users, and system integrators to test third-party OPC client software in a controlled environment.

The package includes an Advanced OPC Simulator supporting OPC Classic Data Access (DA) and Historical Data Access (HDA) specifications. Users can configure custom tags, customize the OPC server address space, and define simulated data sets using CSV files.

With support for simulated process values and historical data playback, the Advanced OPC Simulator is particularly useful for testing historical data retrieval, validating OPC client functionality, and developing or troubleshooting applications that rely on OPC DA and HDA communications.

Available free of charge, OPC Server Simulators provide a practical testing environment for OPC developers, automation engineers, and system integrators who need to verify client-server interoperability and application behavior without relying on live process data.
