This hardware thin client is built to integrate into SIMATIC HMI ecosystems, providing access to centralized HMI resources via SmartAccess, Remote Desktop Protocol (RDP), and Web interfaces, reducing the need for full desktop PCs at the machine. Its compact 15" form factor supports panel mounting and tight installation spaces while delivering the familiar Siemens HMI interface and software stack. Common applications include local operator terminals and remote viewing of PLC-driven processes and dashboards, where a dedicated thin client offers stability, security, and straightforward maintenance within an industrial network. The 6AV6646-0AB21-2AX0 designation identifies the 15" touch variant of Siemens’ SIMATIC Thin Client hardware line, designed for reliable operation in factory environments and to support scalable remote access as part of an integrated automation strategy.
