Help operators find the information they need
An HMI, or Human Machine Interface, presents information that staff use to monitor and, where appropriate, operate machinery. An unclear layout or collection of separate screens makes it harder to see what needs attention.
We start with the operator's work. Which status should be immediately visible? Which alert requires action? Which information is only needed during a fault? We turn those needs into a layout with clear names, recognisable states and readable values.
Combine existing HMI viewing with a new overview
Sometimes a machine screen already provides the right information but can only be viewed at the machine. Elsewhere, an overview across several machines is missing. We assess whether existing screens can be made available in a web application or whether a new view built from PLC data is more useful.
A suitable HMI may support a remote-view connection that can be integrated. A custom web interface can show current readings and batch history alongside it. The available HMI and PLC determine which approach fits.
- Show the status of several machines in one production overview.
- Make existing HMI screens accessible from the same web application.
- Connect current readings with trends and earlier batches.
Design the screens before building the connections
We develop the main layouts with operators and other users. You can check whether information is in the right place before all connections are built. A workstation, tablet or large production display each needs an appropriate layout.
We then connect the interface to the available data. We check names, units and refresh behaviour. A lost connection is clearly indicated so old readings are not mistaken for current information.
Separate viewing from operating machinery
Viewing a production overview is different from operating a machine. We agree who can see screens and whether operation is part of the solution at all. Any control functions require separate permissions, testing and coordination with the machine builder.
Emergency stops, interlocks and other safety functions remain with the machine control system designed for them. The web interface does not replace them. We configure access for the agreed workstations; machine screens do not need to be publicly accessible on the internet.
What does an HMI or production overview cost?
Cost depends on the number of screens and machines, available data and required functions. Bringing existing HMI views together is a different project from designing a complete new production overview.
You receive a proposal covering screens, connections and commissioning. We can begin with one machine or overview, then add more screens, batch history or reports.

We combined HMI screens and batch logging in one local web interface for a Siemens production environment. Staff can view current status, the operator overview and earlier batches in the same place. The case shows how existing machine information and a web application can complement each other.
Frequently asked questions
Do we need to buy new HMI panels?
Not necessarily. We first examine the current screens and connections. Integrating an existing view may be sufficient; in other situations, a new web overview better addresses the need.
Can this work with Siemens, Allen-Bradley, Omron and Mitsubishi?
We assess the combination of PLC, HMI and available connection. The brand alone does not establish whether screen viewing or data collection is possible. We choose a suitable approach for each installation.
Can you also change the software on the physical HMI panel?
This service focuses on web visualisation and integrating HMI viewing with production data. If panel software needs changes, we assess the available engineering software and access, and coordinate the work with the machine builder or automation partner.
Can we combine HMI viewing and batch logging?
Yes. An overview can show current machine information and provide access to earlier batches. We identify which data you need live and which records to retain, so operators and quality staff can work from the same application.
