Do not install under a local admin account if you intend to run the client as a service. Create a dedicated domain or local service account (e.g., OPCClientSvc) with "Log on as a service" and “Act as part of the operating system” privileges.

FactorySoft’s OPC Browser tool is 32-bit. By default, it cannot see 64-bit OPC servers’ registry entries. To fix:

FactorySoft clients often rely on specific OPC Proxy/Stub DLLs. If you install the client but get "Class not registered" or "Interface not supported" errors, you are missing the OPC Core Components.

FactorySoft OPC Client is an OPC Classic (DA) client application used to browse OPC servers, subscribe to item updates, and interact with process data for monitoring or integration. This guide covers prerequisites, installation, basic configuration, testing, and troubleshooting.

FactorySoft OPC Client installs cleanly on modern Windows systems, provided that DCOM and OPC Core Components are correctly set up. It’s an excellent tool for quick OPC DA testing, troubleshooting, or light HMI tasks. However, for production‑grade OPC UA or large‑scale SCADA, consider FactorySoft OPC Gateway or a full‑featured client.

Rating: 4.2 / 5
Deducted 0.8 points for DCOM complexity and lack of 64‑bit build.

The FactorySoft OPC Client is a lightweight tool designed for testing and troubleshooting connections to OPC Servers. Its installation and key features focus on simplicity and broad compatibility with industrial standards. Key Features

Support for Multiple Standards: It typically supports both OPC DA (Data Access) for legacy Windows-based real-time data and OPC UA (Unified Architecture) for modern, secure, platform-independent communication.

Server Browsing: Automatically discovers and lists available OPC servers on local or remote machines, allowing you to browse their address space for specific tags or items.

Real-time Data Monitoring: Provides a live view of tag values, quality codes (e.g., Good, Bad, Uncertain), and timestamps to verify that a server is providing accurate data.

Synchronous & Asynchronous Read/Write: Enables users to manually write values to tags for testing control logic or read them on demand. factorysoft opc client install

Lightweight Footprint: As a testing utility, it is designed to run without heavy system overhead, making it ideal for field diagnostics. Installation Overview

To ensure a successful installation, follow these standard steps for OPC-based software:

System Requirements: Ensure .NET Framework 3.5 or higher is enabled via the Windows "Turn Windows Features on or off" menu.

OPC Core Components: Install the OPC Core Components (redistributables provided by the OPC Foundation) to ensure the necessary DLLs for DCOM/DA communication are present.

Run the Installer: Execute the Setup.exe file provided by FactorySoft and follow the prompts. Administrative privileges are usually required to register the necessary COM components.

Network/Firewall Configuration: If connecting to a remote server, ensure TCP port 4840 (for UA) or the specific DCOM ports are open in your firewall.

Getting your FactorySoft OPC Client up and running is a straightforward process that bridges the gap between your Windows applications and industrial hardware. Whether you are testing a new PLC connection or building a custom HMI, this guide will walk you through the installation steps. 1. System Requirements & Preparation Before starting, ensure your environment is ready:

Operating System: Windows 7, 8, 10, or 11 (32-bit and 64-bit supported).

Framework: Most versions require the .NET Framework 4.0 or higher.

Permissions: Ensure you have Administrative Privileges on the machine to register COM components and DCOM settings. 2. Downloading the Installer

Head to the official FactorySoft website or your provided vendor link to download the latest setup package. It typically comes as a .zip or a standalone .exe installer. 3. The Installation Process

Extract the Files: If you downloaded a ZIP, extract it to a local folder. Avoid running the setup directly from the compressed folder. Installing FactorySoft is not as simple as running a setup

Run Setup.exe: Right-click the installer and select "Run as Administrator."

Follow the Wizard: Click through the license agreement and choose your installation directory.

OPC Core Components: The installer may prompt you to install the OPC Core Components from the OPC Foundation. Accept this step, as these redistributables are essential for any OPC DA/HMI communication to work on Windows.

Finish: Once the progress bar completes, you may be asked to restart your computer to finalize DCOM registrations. 4. Initial Configuration

Once installed, launch the FactorySoft OPC Client. To verify the install:

Discovery: Click on "Connect" or "Server List" to see if it detects local OPC Servers (like Kepware, Matrikon, or RSLinx).

Add Tags: Select a server, browse the address space, and drag a few tags into your watch list.

Validate: Check the "Quality" column. If it says "Good," your installation and connection are successful. Troubleshooting Tip: DCOM Errors

If the client installs but cannot "see" servers on other machines, the issue is likely DCOM permissions. Ensure that both the client and server machines have matching user accounts or that the "Everyone" group is temporarily allowed for testing purposes.
