What is HMI and SCADA software?
Human-machine interface (HMI) software allows operators to monitor, control, and diagnose industrial machines and processes. It displays operating conditions, accepts commands, manages alarms, and provides access to process settings and production data. The software may run on a dedicated operator panel, industrial computer, SCADA workstation, or custom desktop or web application.
When does an operator interface need maintenance?
Operator interfaces require maintenance when their functionality no longer meets requirements, or when their supporting software platform becomes obsolete. Operators may discover faults in existing functionality that make the interface difficult to use or obscure important operating information. A customer-selected replacement panel may also use a different resolution, aspect ratio, operating system, or supported runtime, requiring changes to the application.
New production hardware, operating sequences, or procedures may require additional controls, prompts, and interface logic. Operators might need different information displayed, reorganized screens, or support for additional languages. Changes in access policies may require new authentication methods, user permissions, or audit logging to track operator actions.
How can we help?
Working with operator interface applications requires an understanding of the component systems, their interactions, and the underlying software platforms. Applications are also often distributed in a transformed state that is efficient for a computer but difficult for a person to inspect. Modifying software in this form requires specialized tools and a controlled test environment.
Whether you have complete project files or only a running application and backup, we can investigate the software and determine what can be recovered or changed. Our work stays focused on operator-interface software. When an application change depends on hardware, we document the software-driven requirements and compatibility considerations for your maintenance team or chosen hardware contractor. We document each modification, rebuild, or migration so your organization can understand and maintain the software.
