RSLinx Classic Gateway is part of Rockwell Automation’s RSLinx Classic communications software, used to connect Rockwell/Allen‑Bradley programmable logic controllers (PLCs) and other industrial devices to PC-based applications (like RSLogix/RStudio, FactoryTalk, OPC clients, and custom software). The Gateway component enables networked clients to access device data through Ethernet/IP and other supported drivers, acting as a bridge between local device drivers and remote applications.
RSLinx Classic Gateway provides standard communication connectivity for Rockwell Automation software, but expands this capabilities to remote clients. It allows a single server computer to handle plant-floor communications while sharing that data with multiple remote workstations across a local area network (LAN) or wide area network (WAN). Key Architectural Differences
Always run RSLinx as an administrator if your configured communication drivers fail to start automatically.
Instead of purchasing RSLinx Professional for every machine, a single RSLinx Classic Gateway license serves multiple remote clients.
