What is SCADA?
SCADA stands for Supervisory Control and Data Acquisition.
A SCADA system allows operators and engineers to monitor and supervise industrial processes from a central interface. SCADA systems collect information from PLCs, RTUs, sensors, meters and other field devices and present the information in an easy-to-understand graphical interface.
A modern SCADA system can provide:
- Real-time process monitoring
- Equipment status
- Alarm notifications
- Historical trends
- Production data
- Energy consumption
- Process values
- Reports
- User management
- Data logging
- Remote monitoring
- Supervisory control
SCADA is commonly used in mining, water treatment, wastewater treatment, manufacturing, power generation, agriculture, oil and gas, food processing, bulk materials handling and municipal infrastructure.
What is HMI?
HMI stands for Human Machine Interface.
An HMI is the graphical interface through which an operator interacts with a machine, PLC or industrial process.
An industrial HMI can display:
- Machine status
- Motor status
- Pump status
- Temperatures
- Pressure
- Flow
- Level
- Speed
- Production information
- Alarms
- Faults
- Setpoints
- Trends
- Maintenance information
HMI systems range from compact touchscreen operator panels installed directly on machines to larger industrial PC-based interfaces used in control rooms.
SCADA vs HMI
Although SCADA and HMI are closely related, they are not exactly the same.
| HMI | SCADA |
|---|---|
| Usually interfaces with a machine or local process | Supervises larger systems and processes |
| Often installed close to equipment | Often operates from a control room or server environment |
| Operator interface | Supervisory monitoring and control |
| Machine-level visualisation | Plant-wide visualisation |
| Typically smaller-scale | Can support large distributed systems |
| Local alarms and controls | Centralised alarms, trends, reports and historical data |
| Commonly connected to one PLC | Can communicate with multiple PLCs, RTUs and devices |
For many industrial projects, HMI and SCADA work together as part of a complete PLC and industrial automation architecture.

- Historical data requirements
- Alarm requirements
- Reporting requirements
- Remote access requirements
- Cybersecurity requirements
- Existing PLC manufacturer
- Existing plant infrastructure
- Future expansion
- Software licensing
- Availability of local technical support
- Availability of replacement hardware
A SCADA system should be selected according to the whole automation architecture, not just the software package.
Tips When Buying SCADA & HMI Equipment in South Africa
Tip 1 – Confirm the Exact Part Number
Always provide the exact manufacturer part number where possible.
Tip 2 – Check Hardware Compatibility
Confirm voltage, screen size, communication ports, I/O requirements and mounting dimensions.
Tip 3 – Check Firmware
Different firmware versions may not be compatible with existing PLC or SCADA systems.
Tip 4 – Check Software Licensing
Some SCADA platforms require licences based on tags, users, clients, runtime or features.
Tip 5 – Check Communication Protocols
Make sure the HMI or SCADA system supports the PLC and field devices being used.
Tip 6 – Keep Backups
Maintain backups of:
- PLC programs
- HMI projects
- SCADA projects
- PLC configuration
- HMI configuration
- SCADA databases
- Licences
- Firmware
- Network configuration
Tip 7 – Plan for Obsolescence
When upgrading a system, consider the availability of spare parts and software support for the next several years.
Tip 8 – Consider Cybersecurity
SCADA systems are part of an industrial OT environment. Remote access, user accounts, network segmentation, firewalls and secure communication should be considered from the beginning.
Tip 9 – Don’t Replace Equipment Without Checking the Application
A visually similar HMI or PLC module may not be electrically, mechanically or software compatible.
Tip 10 – Send Photos and Existing Details
For replacement enquiries, provide:
- Equipment photo
- Manufacturer
- Model
- Part number
- Serial number
- Existing PLC
- Existing HMI
- SCADA software
- Quantity
- Application
