Product Description

Schneider Electric HMIST6700 — Harmony ST6 15.6" Wide Touch Panel Screen

There's a certain clarity that comes with a well-sized panel on a production machine: operators find what they need immediately, alarms are hard to miss, and the interface earns confidence rather than frustration. At 15.6 inches wide with a 16:9 aspect ratio and 1366×768 FWXGA resolution, the HMIST6700 is the largest panel in Schneider Electric's Harmony ST6 Basic HMI range — built to deliver that kind of working clarity in industrial environments where smaller screens simply don't have the real estate to do the job.

Harmony ST6: The Right HMI for the Whole Machine

Schneider Electric's Harmony ST6 range covers panel sizes from 7 inches up to 15.6 inches, all sharing a consistent architecture — the same ARM Cortex-A8 processor, the same EcoStruxure Operator Terminal Expert software environment, the same communication port layout, and the same flush-mount cutout philosophy that makes panel integration straightforward.

The HMIST6700 is the 15.6-inch model in that family. The choice to go this size is almost always driven by the same factors: the number of process screens needed, the complexity of the visualizations, or simply the ergonomics of a machine where operators interact with the panel at arm's length. At this size, the 1366×768 FWXGA display provides enough horizontal space to run meaningful trend charts, alarm tables, and navigation alongside each other without crowding — something that becomes noticeably constrained on smaller panels.

The Display: 50,000-Hour LED Backlight and Resistive Touch

The choice of resistive touch for the HMIST6700 is deliberate, and it matters for industrial environments. Resistive panels respond to any object that applies pressure — gloved fingers, stylus tips, objects on the screen — while capacitive panels typically require bare skin or special gloves. In food processing, chemical environments, or any application where operators wear gloves routinely, resistive touch is the practical technology.

The LED-backlit TFT display is rated for 50,000 hours of backlight life. At continuous operation, that translates to roughly 5.7 years before the backlight reaches its nominal half-brightness point — a meaningful figure for a machine expected to run 24/7. The backlight is also field-replaceable, which extends the working life of the panel beyond the initial backlight cycle.

Sixteen brightness levels allow the display to be tuned for ambient light conditions — brighter for well-lit factory floors, dimmed for control rooms where operators work close to the screen over long shifts.

Communication: Dual Ethernet and Two Serial Ports

The HMIST6700 carries two independent Ethernet ports at 10/100 Mbit/s. In practice, this is more useful than it might initially appear: one port can connect to the plant PROFINET or EtherNet/IP network for PLC communication, while the second connects to a corporate IT network, a remote access router, or an energy monitoring system — without requiring a managed switch to separate the traffic or bridge the networks.

Serial communication covers both common industrial standards. COM1 (RS-232C, Sub-D 9-pin) handles point-to-point connections to drives, barcode readers, printers, and older PLCs. COM2 (RS-485, RJ45) handles multi-drop serial networks at baud rates up to 115,200 bps. Together they provide coverage for the installed base of serial devices that remain in active service across most industrial sites.

The USB Type A port supports memory sticks for project uploads, recipe transfers, alarm logs, and firmware updates — no laptop required on the factory floor for routine data operations. The USB Micro-B port provides the programming connection from an engineering workstation.

IP65 Front Panel Protection

The front panel carries IP65 certification under IEC 61131-2, which means it is fully sealed against dust ingress and resistant to water jets from any direction. NEMA 4 and NEMA 13 ratings cover indoor use and protection against splashing oil and coolants respectively — practical approvals for machine tool, packaging, and food & beverage environments.

The rear of the panel is rated IP20, which is standard for an open-style panel module installed inside a sealed control cabinet. The front gasket is replaceable as part of routine maintenance, keeping the IP65 rating intact throughout the service life of the panel.

Target Industries and Applications

The HMIST6700 sees regular deployment across a well-defined set of industries where 15-inch visualization adds tangible value:

Packaging machinery — where recipe management, format changeovers, and multi-station coordination benefit from a large screen with clear navigation. Food & beverage processing — where IP65 washdown protection and glove-friendly resistive touch are non-negotiable. HVAC and building automation — where system diagrams, sensor readings, and setpoint management all coexist on one screen. Textile and weaving machinery — where pattern visualization and process monitoring run in parallel. Compressor and pump systems — where trend data, alarm history, and real-time process values need to be legible at a distance.

Frequently Asked Questions

Q: What software is used to program the HMIST6700?

A: The HMIST6700 is programmed using EcoStruxure Operator Terminal Expert (formerly known as Vijeo Designer), Schneider Electric's HMI configuration software. It is available for download from Schneider Electric's software portal. The USB Micro-B port on the panel is used for the connection between the engineering PC and the panel during project download.

Q: Does the HMIST6700 have two separate Ethernet ports, and can they be on different networks?

A: Yes. The panel has two independent 10/100BASE-T Ethernet ports. They can be configured for different network segments — for example, one for PLC communication on the machine network and one for remote access or IT integration on a separate network. This eliminates the need for an external switch when two network connections are required.

Q: What is the difference between the HMIST6700 and the smaller Harmony ST6 models?

A: All Harmony ST6 panels share the same processor (ARM Cortex-A8, 800 MHz), memory configuration, communication ports, and software platform. The HMIST6700 differs only in screen size — at 15.6 inches with 1366×768 FWXGA resolution, it is the largest and highest-resolution panel in the ST6 range. Smaller models include the HMIST6500 (12.1 inch), HMIST6600 (12.1 inch wide), and HMIST6400 (10.4 inch).

Q: Does the panel support Modbus communication?

A: Yes. The HMIST6700 natively supports Modbus RTU over COM1 (RS-232C) and COM2 (RS-485), as well as Modbus TCP over either Ethernet port. Uni-TE and a wide range of third-party driver protocols are also available within EcoStruxure Operator Terminal Expert.

Q: Is the touch screen usable with gloves?

A: Yes. The HMIST6700 uses an analogue resistive touch panel, which responds to pressure rather than electrical capacitance. It works with gloved hands, styluses, and other objects that apply mechanical force to the screen surface. This makes it suitable for environments where operators wear work gloves routinely.

Q: What is the expected backlight service life?

A: The LED backlight is rated for 50,000 hours of operation. At continuous 24/7 use, this equates to approximately 5.7 years before the backlight reaches half its original brightness. The backlight is field-replaceable, and replacement kits are available separately as a spare part.

Q: What panel cut-out dimensions are required for installation?

A: The HMIST6700 mounts flush into a panel cutout using 6 screws, accommodating panel thicknesses from 1.6 mm to 5 mm. The specific cutout dimensions should be confirmed from the Schneider Electric installation documentation included with the unit. The same cutout dimensions apply to the HMIST6400, HMIST6500, and HMIST6600 models in the ST6 family for the 64/65/66/6700 installation procedure.

Q: What does "Genuine New" mean for this listing?

A: The unit is factory-new, genuine Schneider Electric manufacture, in original factory packaging, unused and uninstalled. It has not been previously powered, configured, or deployed. This is not refurbished, repaired, or cosmetically reconditioned surplus inventory.
