Industrial HMI interface design

We design operator interfaces for industrial panels: which values belong on which screen, how they are addressed, and how an abnormal state is recognised without relying on colour. The functional demo below is free to try. Template packages andpanel implementationare quoted per project once the panel, controller and point list are confirmed.

All four screens are interactive. Readings are simulated in your browser, so this shows screen design and operator workflow, not plant data.

The same job on a real panel

Panel-mounted operator interface showing a chiller sequence screen with pump and valve states
Customer site — a chiller sequence screen on a panel-mounted interface.

The demo above is a cleanroom air-handling unit. This is the same class of job installed and running: one screen carrying the sequence, the pump and valve states, and the alarm condition an operator has to act on.

Screen architecture is decided before artwork either way — which values belong on which screen, how they are addressed, and how an abnormal state is recognised without relying on colour alone.

Alarm states, as operators actually see them

The demo shows how an abnormal state is meant to read. These are the same job on customer machines.

How a design runs

Step 01

Send the panel and the point list

Panel model, controller, I/O list and the machine states an operator has to act on. A photo of the existing screen helps if one exists.

Step 02

Screen architecture first

We return which values belong on which screen and how they are addressed, before any artwork is drawn. This is the step that decides whether the interface works.

Step 03

Design and review

Screens are laid out against your panel resolution, with the state ladder and alarm discipline agreed in writing.

Step 04

Hand-off or implementation

Take the design package and build it yourself, or we build it on your panel and controller. Both are quoted against the agreed scope.

What this does not cover

  • Screen design is not controller logic. Interlocks, sequences and safety functions stay with the responsible engineer.
  • A point list is a starting structure. Addressing, protocol mapping and I/O count are confirmed against your controller before configuration begins.
  • We do not resell vendor project files. Every design is authored here and its provenance is recorded.
  • Price is agreed per project after the scope is confirmed. Nothing is charged through this website.

Questions asked before a quote

Can I try the interface before paying anything?

Yes. The demo below runs in your browser with all four screens interactive, and the sample point list and equipment schematic download free. That is enough to judge the screen structure and the alarm discipline before any money is discussed.

What does a template package contain?

The editable design sources, every page element exported separately as a slice, and high-resolution artwork at panel resolution, covering a stated number of screens. It does not contain a compiled panel project or controller logic — those are implementation work.

PLC and HMI programming

Do you design for panels you do not supply?

Yes. The design is dimensioned against your panel resolution whoever made it. Where the panel is one of the HMIs we supply, the layout is checked against its exact pixel grid.

See the HMI panels we supply

How is this priced?

Per project, after the panel, controller, point count and screen count are confirmed. Payment is arranged directly with you rather than through this website.

Send the panel and the point list

Panel model, controller and the states an operator has to act on. We return the screen architecture before any price is agreed. Already have a project to assess? Start with ascoped review.
