It runs on a 24 V DC external supply, is rated IP20 for in-cabinet mounting, and supports Modbus Uni-TE plus third-party protocols for connectivity to a range of PLCs and controllers. The HMIST6400 uses a single-touch analogue resistive touch panel over a 7-inch colour TFT LCD. The ARM Cortex-A8 at 800 MHz handles screen rendering, recipe management, and communication tasks. The 1 GB device memory and 128 MB user data memory provide capacity for application pages, alarms, and data logging — the 512 KB backup memory retains real-time clock and critical variables during power loss. On-board Ethernet at 10/100BASE supports Modbus Uni-TE and third-party protocols, allowing direct connection to Schneider and other automation controllers without an external gateway. The backlight is rated for 50000 hours white, and brightness adjusts across 16 levels. ## Applications This HMI is used on packaging lines, conveyor systems, material handling cells, and small process skids where a 7-inch operator panel provides machine status, alarm management, and parameter entry. The resistive touch screen suits gloved-hand operation common in food, beverage, and light industrial environments. As an active Harmony ST6 model, the HMIST6400 remains in current production. Sourcing is through standard distribution channels; confirm lead time on the RFQ.","metaTitle":"Schneider HMIST6400 Harmony ST6 7\" HMI, 800x480, ARM Cortex-A8","metaDescription":"Schneider HMIST6400 Harmony ST6 HMI operator interface: 7\" colour TFT, 800x480 WVGA, ARM Cortex-A8 800 MHz, 1 GB device memory, Modbus Uni-TE, IP20, 24 V DC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Depth":"1.8 in (45 mm)","Width":"8.2 in (208 mm)","Height":"6.02 in (153 mm)","Supply":"External supply","Marking":"CE","Category":"US10MC222565","Standards":"IEC 61000-6-4 IEC 61000-6-2 IEC 61131-2 UL 61010-2-201 CSA C22.2 No 61010-2-201","Brightness":"16 levels","Directives":"2014/35/EU - low voltage directive 2014/30/EU - electromagnetic compatibility","Fixing mode":"By 4 screws 1.6...5 mm thick panel UL 61010-2-201 By 4 screws IEC 61131-2 By 4 screws IEC 61000-6-2","Touch panel":"Single touch analogue resistive","Display Type":"Colour TFT LCD","Display size":"7 inch","Port Ethernet":"10/100BASE","Product brand":"Schneider Electric Modicon Mitsubishi Melsec Omron Sysmac Rockwell Automation Allen-Bradley Siemens Simatic","Character font":"ASCII ASCII (European characters) Chinese (simplified Chinese) Japanese (ANK, Kanji) Katakana Korean Taiwanese (traditional Chinese)","Display colour":"16 million colours","Front material":"Aluminium","Inrush current":"30 A","Processor name":"ARM Cortex-A8","Realtime clock":"Built-in 0...50 °C Built-in 10...90 % RH","Number of pages":"200 application pages","lifecycle_stage":"current","Local signalling":"Status LED green, steady offline Status LED green, steady operating Status LED green, flashing operating Status LED green, faded stand-by Status LED orange, flashing software starting up Status LED red, steady power supply (ON) Status LED red, flashing operating Status LED red, off power supply (OFF)","Range of Product":"Harmony ST6","Shock resistance":"147 m/s² 11 ms X, Y, Z directions for 3 times)IEC 61131-2","Relative humidity":"10...90 % non-condensing","Backlight lifespan":"50000 hours white","Cut-out dimensions":"190 x 135 mm panel cut dimension","Display Resolution":"800 x 480 pixels WVGA","Enclosure Material":"PC","Memory description":"1 GB device memory 128 MB user data memory 512 KB backup memory","Operating altitude":"6561.68 ft (2000 m)","Vibration resistance":"+/- 3.5 mm 5...9 Hz) X, Y, Z directions for 10 cycles (approx. 100 min) IEC 61131-2 9.8 m/s² 9...150 Hz)","Nbr. of units in pkg.":"1","Downloadable protocols":"Modbus Uni-TE Third party protocols","Power Consumption in W":"9 W","IP degree of protection":"IP20 IEC 61131-2 rear panel) IP65 IEC 61131-2 front panel)","Immunity to microbreaks":"5 ms","NEMA degree of protection":"NEMA 4 front panel (indoor use) NEMA 13 front panel (in enclosure)","Product or Component Type":"Touch panel screen","[Us] rated supply voltage":"24 V DC +/- 20 %)","Integrated connection type":"1 COM1 serial link - 1 SUB-D 9-pin female - RS232C 2400...115200 bps)bottom 1 COM2 serial link - female RJ45 - RS485 2400...115200 bps)back COM2 serial link 2400...187500 bps)back 1 USB 2.0 type Abottom 1 USB 2.0 type micro B 2 Ethernet","Electromagnetic compatibility":"Electrical fast transient/burst immunity test - test level: 2 kV (power ports) conforming to IEC 61000-4-4 Electrical fast transient/burst immunity test - test level: 1 kV (signal ports) Electrostatic discharge immunity test - test level: 6 kV (contact discharge) conforming to IEC 61000-4-2 level 3 Electrostatic discharge immunity test - test level: 8 kV (air discharge)","Ambient Air Temperature for Storage":"-4...140 °F (-20...60 °C)","Ambient Air Temperature for Operation":"32...122 °F (0...50 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$374.65 – $966.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7af824bd6d3eabe9286f840908df9d69.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/HMIST6400/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/HMIST6400","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/HMIST6400 when reusing this data.
