Choosing Human Machine Interface (HMI) components

HMI replacement is one of the most exact part-number-driven swaps in industrial automation: the same screen size and visual appearance can hide entirely different processors, firmware, project file formats, and communication protocols. Replacing by "Siemens 10-inch touchscreen" is almost guaranteed to fail.

Specs to confirm before ordering:

  • Exact OEM part number including all suffix codes
  • Display size and resolution
  • Firmware or runtime version (e.g., PanelView Plus 6 vs Plus 7 do not share project files)
  • Communication interface: Ethernet, RS-232/422/485, Profibus, DeviceNet, ControlNet, MPI
  • Supply voltage (most are 24 VDC; some legacy AC models)
  • Cut-out dimensions for panel mount (varies between generations)
  • Project file software required to deploy (FactoryTalk View, WinCC, GT Designer, NB-Designer)

Common gotchas: PanelView Plus 700 (2711P-T7C) and PanelView Plus 6 700 share size and shape but are not project-compatible — the .mer file from one will not run on the other without conversion in FactoryTalk View Studio. Siemens KTP and TP series have similar appearance across generations, but Comfort Panels do not load Smart Panel projects. Mitsubishi GOT2000 will run most GOT1000 projects with conversion, but the reverse is not true. Pro-face GP-3000 and GP-4000 require separate project conversions in GP-Pro EX.

Typical applications: machine operator panels on injection molders, packaging-line interfaces, water-treatment SCADA terminals, and OEM equipment in food, automotive, and pharmaceutical plants. When a legacy HMI fails and the OEM no longer makes that exact part, replacing in kind from surplus avoids re-developing the entire project file in a newer software version — a job that can run dozens to hundreds of engineering hours on a complex screen.

For obsolete HMIs and operator panels, request a quote with the full OEM number.

Can you find obsolete PanelView and Siemens HMIs?
Yes. Discontinued PanelView Standard, PanelView Plus 6, S7 OP/TP/MP, and similar legacy displays are core inventory. Send the full part number for a quote.
Will my existing project file run on a replacement HMI?
If the part number matches exactly, yes. If only a newer-generation unit is available, the project usually needs conversion in the OEM software. We will state the unit's generation before purchase so you can plan for it.
Do you preload the customer project before shipping?
No. The HMI ships in its factory or last-imaged state. The end user or OEM integrator loads the application program with the appropriate OEM software.
Are these new or surplus?
Both. New-old-stock and tested surplus units, sometimes refurbished. Each is labeled with its condition before purchase, and the 12-month functional warranty applies to all.
What if the touchscreen calibration drifts?
Most legacy resistive panels have a calibration mode reachable from a startup key combination — see the OEM manual. If the touch surface itself is failing, that is a warranty event in the 12-month window.
Do you ship HMIs internationally?
Yes. International orders ship free over $350. HMIs are packed with original or equivalent protective packaging to prevent screen damage in transit.
