TOP Server Reviews & Product Details

TOP Server is the most comprehensive industrial OPC Server platform provided by Software Toolbox. It delivers reliable, enterprise-grade connectivity between industrial devices and software applications, serving as the critical communications bridge in modern industrial automation environments. At its core, TOP Server connects PLCs, DCS systems, flow computers, RTUs, and other industrial devices from virtually any manufacturer through a library of 140+ proven device drivers. These drivers span individual protocol-specific options as well as bundled vertical industry suites covering Manufacturing, Oil &; Gas, Power & Utilities, IT & Infrastructure, and Building Automation - enabling organizations to select the exact connectivity they need. TOP Server's built-in server interfaces include OPC DA (Classic), OPC UA, OPC AE (Alarms & Events), OPC HDA (Historical Data Access), OPC .NET 3.0 (formerly OPC Xi), and native AVEVA (formerly Wonderware) SuiteLink - all included with any driver license, with no additional gateway software required. This makes TOP Server compatible with virtually any OPC-compliant HMI, SCADA, Historian, and MES system on the market. Designed for 24/7 industrial operations, TOP Server includes built-in redundancy and failover support, comprehensive cybersecurity features, and Active Directory integration (introduced in V7) for streamlined user and group management. The platform delivers millisecond-level data updates, making it suitable for feeding unified namespaces, data platforms, MQTT brokers, cloud services, and AI agents with fresh, real-time operational data. TOP Server's modular, plug-in architecture allows users to start with a single driver or suite and expand over time by adding additional drivers or suites to the same installation. Optional plug-ins include a Local Historian, ODBC DataLogger, Advanced Tags, SNMP Agent, and more. The RESTful Configuration API is included at no additional charge with any license, enabling programmatic management of channels, devices, tags, and configurations from external applications. The configuration interface is designed for both small and large-scale deployments, with a common setup and troubleshooting methodology across all 140+ drivers -reducing training time and total cost of ownership. Built-in startup and testing tools include the OPC Quick Client, Communications Protocol Diagnostics, and a detailed Event Log for rapid troubleshooting. Licensing is per machine (perpetual or subscription), with no artificial limits on the number of tags, connected devices, or client applications for standard licenses. All licenses include the first year of support and maintenance. A fully functional free trial is available, running for 2-hour sessions with no tag or device count restrictions. TOP Server is used across industries including discrete and process manufacturing, oil and gas, power generation and utilities, IT/data center infrastructure monitoring, and building automation. It integrates with HMI, SCADA, MES, ERP, Historian, and database systems (SQL, Access, Oracle), and supports cloud and IIoT connectivity via MQTT and REST interfaces. Thousands of companies worldwide rely on TOP Server for their industrial connectivity needs.
