Schneider Electric HMIST6200 Harmony ST6 4in Touch Panel

HMIST6200: 4 inch Harmony ST6 widescreen touch panel

The HMIST6200 is a Schneider Electric Harmony ST6 touch panel with a 4 inch widescreen colour TFT display at 480 x 272 pixels, 16 million colours and a single-touch analogue resistive layer. It runs on an ARM Cortex-A8 processor with 512 MB device memory, and works from 24 V DC. This unit is the compact member: a 4 inch widescreen terminal with a single serial port and a single Ethernet port, aimed at a single machine, a small skid or a local start-stop and alarm station. Seven Star LLC supplies the HMIST6200 in Oman and the GCC as an independent supplier based in Muscat.

The reference carries the family name HMIST6 followed by a size-dependent number; the datasheets in this group show 200 for 4 inch, 600 for 12 inch and 700 for 15 inch, and the descriptions give the COM and Ethernet counts as 1 Ethernet. The datasheet does not publish an ordering key, so treat the reference as a catalogue number and verify the description before ordering.

Selection checklist for the HMIST6200

• Display: 4 inch at 480 × 272 pixels.
• Communication: 1 Ethernet and the serial ports described above must fit the controller wiring.
• Supply: 24 V DC with a 30 A inrush.
• Door: cut-out 118.5 x 92.5 mm, weight 0.4 kg.
• Operating temperature limit of 50 °C compared with the cabinet temperature on site.

Typical uses of the HMIST6200 in Oman and the GCC

Small machine builders, pump skids and utility cabinets use a compact panel of this size to show start-stop states, set-points and alarms next to the equipment. The 50 °C operating limit is lower than that of some other panels in this lane, so Gulf installations should keep the panel behind a cooled or well-ventilated door.

Mounting and maintenance of the HMIST6200

Fit the clamps evenly so the front gasket seals the door, wire the 24 V DC supply with correct polarity, and separate communication wiring from power cabling. After powering up, load the application, test every communication link and check the real-time clock. Keep the project file archived since a replacement panel must be reloaded. Clean the screen with a soft cloth and avoid solvents.

The cut-out is 118.5 x 92.5 mm for plates 1.6 to 5 mm thick, fixed by 2 screws. The outside dimensions are 134.5 × 108.5 × 43 mm and the weight is 0.4 kg. The small body can be fitted to a narrow control desk or machine fascia. Check that the door can take the weight and leave the free space shown on the datasheet drawing behind the panel.

The HMIST6200 next to its ST6 siblings

The three ST6 references in this group share the processor, 24 V DC supply, resistive touch and IP65 front, and differ in screen, memory, ports and size.

The 4.3 inch Harmony STO/STU panel HMISTO715 from the same lane is a smaller, lower-power alternative with a different software package.

Power, environment and approvals of the HMIST6200

The supply is 24 V DC ± 20 % with a power consumption of 6.9 W and an inrush current of 30 A, so the supply must be sized for the start-up peak. The datasheet states immunity to micro-breaks of 2 ms, operating temperature of 0 to 50 °C, storage from −20 to 60 °C and humidity from 10 to 90 % without condensation, at up to 2000 m. The front is rated IP65 with NEMA 4 (indoor) and NEMA 13 (in an enclosure), and the rear is IP20.

Standards listed are IEC 61000-6-4, IEC 61000-6-2, IEC 61131-2, UL 61010-2-201 and CSA C22.2 No 61010-2-201, and the certifications are CSA, CE and UKCA, with the low-voltage and EMC directives stated. Shock is 147 m/s² for 11 ms and vibration is ±3.5 mm at 5 to 9 Hz and 9.8 m/s² at 9 to 150 Hz.

Connections and protocols on the HMIST6200

Connections on this panel are: COM1 SUB-D 9-pin female RS232C/RS485 (2400–115200 bps; 2400–187500 bps on the back port); USB 2.0 type A at the back; USB 2.0 micro B at the bottom; Ethernet 10/100BASE. The datasheet lists downloadable protocols as Modbus, Uni-TE and third-party drivers, with the third-party brand list covering Schneider Electric Modicon, Mitsubishi Melsec, Omron Sysmac, Rockwell Automation Allen-Bradley and Siemens Simatic. It also lists 200 application pages and a built-in real-time clock, which together describe the size of project the panel is meant for. The datasheet does not name the engineering software, so confirm the required project tool with the supplier of your controller.
