In today’s world of industrial automation, HMI SCADA software plays a vital role in controlling, monitoring, and visualizing complex processes across industries. Whether you’re operating a Siemens PLC, Mitsubishi controller, or Omron automation system, understanding how HMI (Human Machine Interface) and SCADA (Supervisory Control and Data Acquisition) software work together can transform the efficiency and performance of your production line.
At PLC Unlock, we provide unlocked and licensed versions of HMI and SCADA software from top brands such as Siemens, Delta, Allen-Bradley, Omron, Pro-face, Panasonic, and many others – helping automation professionals access the tools they need without restrictions.
HMI (Human Machine Interface) software allows humans to interact with machines, PLCs, and industrial control systems. It provides a graphical visualization of machines or processes – typically displayed on a touchscreen, industrial PC, or monitor.
An HMI screen displays real-time data such as:
Popular HMI software brands include:
Each of these software packages enables seamless communication with PLCs, making it easier to monitor and control industrial operations.
SCADA (Supervisory Control and Data Acquisition) software is used for large-scale industrial systems where multiple PLCs, sensors, and controllers need to be monitored and controlled from one central point.
SCADA collects data from different devices (PLCs, RTUs, sensors) across the plant, visualizes it on a dashboard, and stores it for historical analysis.
This systems are typically used in:
Some popular SCADA software you can find on our website include:
Although HMI and SCADA are closely related, they serve different purposes within the automation hierarchy.
| Feature | HMI | SCADA |
| Function | Interface between operator and machine | Centralized control of multiple systems |
| Scope | Localized, single machine or process | Plant-wide or multi-site control |
| Data Storage | Minimal or none | Long-term data logging and trend analysis |
| Communication | Direct PLC connection | Networked PLCs, RTUs, and sensors |
| Example Software | Delta DOPSoft, Siemens WinCC Flexible | Siemens WinCC, CitectSCADA, FactoryTalk View |
In most industrial environments, HMI and SCADA work together – HMI provides local visualization while SCADA supervises multiple systems remotely.
At the heart of every automation system is a PLC (Programmable Logic Controller) – and HMI/SCADA software acts as the visual and supervisory layer that interacts with it.
The workflow is as follows:
Whether you use Siemens Step7, Mitsubishi GX Works3, Omron CX-Programmer, or Delta WPLSoft, you can connect them seamlessly to your HMI or SCADA system using our software solutions.
Operators can instantly visualize process data and detect abnormal conditions before failures occur.
HMI screens and SCADA dashboards simplify operations, reduce human error, and speed up decision-making.
SCADA software allows centralized monitoring and control of distributed systems – saving manpower and improving reliability.
Historical trend analysis and report generation help optimize production efficiency.
Automatic alerts notify engineers of process deviations or critical alarms, ensuring immediate action.
