WHAT SCADA DOES
From Industrial Data to Operational Information
A SCADA system continuously collects information from the industrial environment and transforms it into information that operators and engineers can use.
Real-Time Monitoring
Visualisation of machine and process conditions as they happen.
Operators can monitor:
- Machine states
- Process values
- Production status
- Temperatures
- Pressures
- Speeds
- Levels
- Equipment status
Alarm Management
SCADA provides structured visibility of abnormal conditions.
Alarm systems can include:
- Alarm priorities
- Alarm history
- Acknowledgement
- Event timestamps
- Operator notifications
- Diagnostic information
The objective is not simply to display an alarm, but to provide enough information to understand what requires attention.
Process Visualisation
Complex industrial processes are represented through intuitive graphical interfaces.
Depending on the application, screens can include:
- Process diagrams
- Machine layouts
- Equipment status
- Production counters
- Trends
- Parameters
- Operating modes
Historical Data
SCADA can store and visualise historical process information, allowing engineers and operators to analyse what happened over time.
Examples include:
- Production trends
- Temperature history
- Machine cycles
- Alarm history
- Process values
- Equipment performance
SCADA ARCHITECTURE
Designed as an Industrial Control Layer
A robust supervisory architecture seamlessly bridges field-level automation with operator control and long-term data collection.
SCADA ENGINEERING
HMI VS SCADA ARCHITECTURE
Although HMI and SCADA systems are closely related, they normally serve different operational purposes across the plant floor:
SCADA APPLICATION DEVELOPMENT
SCADA development is more than creating visual graphics. The application must accurately represent the actual behavior of the industrial process under all operating conditions.
TRENDS & PROCESS DATA
Real-time values show what is happening now. Historical trends show what happened before. SCADA applications can provide graphical analysis of process variables such as:
Static readings only tell part of the story. Capturing continuous time-series data transforms isolated values into actionable operational intelligence.
ALARM & EVENT MANAGEMENT
Alarm and event management is an essential part of an industrial SCADA application, ensuring rapid fault identification and resolution.
Unstructured alarm floods overwhelm operators. GPLG structures alarm systems around operational context, priority, and clear lifecycle tracking.
UNIFIED SUPERVISORY CONTROL (SCADA)
For larger industrial installations, SCADA provides a centralized, unified view across distributed machines and cells.
PLC → Mach.
PLC → Mach.
PLC → Mach.
Fragmented monitoring forces operators to interpret disparate interfaces for each manufacturing cell, increasing cognitive load and error risk. Centralizing control eliminates these barriers.
SCADA & HMI PLATFORMS
Rather than listing every available market solution, we focus strictly on the industrial SCADA and HMI platforms we have hands-on experience configuring, programming, and deploying across real production environments:
GPLG selects and implements supervisory software based entirely on the specific demands of each plant architecture, existing hardware footprint, and long-term operational roadmap.
SCADA INTERFACE DESIGN
A good SCADA interface should allow an operator to understand the state of a process quickly and make informed decisions under pressure.
By eliminating cognitive overload and prioritizing high-visibility indicators, control rooms maintain peak situational awareness during normal operations and critical events.
SCADA INTEGRATION
SCADA systems can be integrated with the wider industrial environment when required. Depending on the project architecture, this can include:
Seamless data exchange across the automation pyramid requires precise protocol selection and network planning to prevent bottlenecks and ensure real-time responsiveness.
SCADA FOR EXISTING SYSTEMS
Existing SCADA systems often evolve over many years. GPLG can assess existing applications and identify opportunities for modernisation, covering:
Upgrading legacy infrastructure should never mean losing the hard-earned operational insights and process rules embedded over years of plant operation.
SCADA ENGINEERING PRINCIPLES
GPLG applies rigorous engineering standards to every supervisory project, ensuring long-term reliability, scalability, and operator clarity.
A Clearer View of Your Industrial Process
GPLG develops SCADA systems that transform industrial process data into clear, structured and actionable information.
From individual machines to complete production environments, we engineer supervisory systems around the way your operation actually works.
