FactorySoft (historically associated with eMation) provides developer-focused toolkits for building OPC Alarms & Events (A&E) and Data Access (DA) client applications. Installation Guide
Because these are developer toolkits rather than standalone consumer software, the installation process usually integrates into your development environment (like Visual Studio). Download the Toolkit : Obtain the latest version of the FactorySoft OPC A&E Client Toolkit or the DA variant. Run the Installer : Execute the
file. This typically installs DLLs, header files, and sample projects to your local drive. Register Components
: During installation, the toolkit usually registers necessary COM/DCOM components. Ensure you have administrative privileges, as OPC Classic relies heavily on Windows registry settings. Configure DCOM factorysoft opc client install
: If your client needs to connect to a remote server, you must configure Windows DCOM settings (via
) to allow the FactorySoft components to communicate across the network. Integration
: Open your IDE (e.g., Visual Studio) and add references to the FactorySoft DLLs installed in step 2 to begin building your client. Review: FactorySoft OPC Client Toolkit
Based on developer feedback and technical documentation, here is a review of the toolkit's performance in industrial environments. Ease of Use for Developers
: The toolkit is highly regarded for its "clean, developer-friendly API". It abstracts the complex DCOM and A&E specifications, allowing developers to focus on application logic rather than low-level communication protocols. Reliability : It is designed for building reliable industrial applications John O’Connell is a control systems integrator with
, particularly for subscription and filtering workflows in Alarms & Events. Legacy Support : It is a solid choice for maintaining or creating OPC Classic (DA/A&E) connections
, which are still prevalent in many factory floor systems today. Integration Flexibility
: The license often allows for redistribution in commercial applications, making it a flexible choice for OEMs and system integrators. Limitations OPC UA Support
: While FactorySoft has historically focused on OPC Classic, modern industrial standards are shifting toward OPC UA. Users looking for native, cross-platform UA support might find these toolkits more limited compared to newer frameworks like Open Automation Software
: Some components and documentation are older, which may require additional troubleshooting on modern Windows 10/11 environments due to stricter DCOM security requirements comparison Finish and reboot if prompted

Unlike many modern installers, FactorySoft requires a reboot to finalize COM registration. Do not postpone this—unregistered class factories cause "Class not registered (0x80040154)" errors.
| Component | Requirement | |-----------|--------------| | OS | Windows 7, 8, 10, 11 (32/64-bit) | | .NET Framework | 4.0 or later | | OPC Core Components | Installed (e.g., from OPC Foundation) | | RAM | 512 MB minimum | | Disk Space | ~50 MB | | Admin Rights | Required for installation |
The FactorySoft installer will attempt to set DCOM launch permissions. However, due to Windows security hardening, this step frequently fails silently. After the progress bar completes, note the summary: "DCOM permissions may need manual configuration."
