Schneider Electric HMISTU655S Magelis HMI Software

Schneider Electric HMISTU655S Magelis HMI is a compact 3.5-inch color touch-screen human-machine interface in the Magelis STU/Harmony line. It uses a TFT LCD with a 320 × 240 pixel resolution, displaying up to 65K colors with LED backlighting for clear, legible graphics in typical industrial environments. The unit provides a serial port and Ethernet connectivity for straightforward integration with PLCs and networked devices, enabling local control and remote access workflows. Project development is performed with Schneider Electric's Vijeo Designer software; older revisions specify Vijeo Designer 5.1 or later for HMISTU655 variants, while newer revisions (PV ≥ 3) require Vijeo Designer 6.1 SP1 or later. The HMISTU655S is designed for simple operator interfaces and basic process monitoring, supporting standard HMI objects such as buttons, text fields, and graphical elements to present and control machine status and parameters.
