Scalable Distributed SCADA for Large Industrial Applications
Build large SCADA systems by combining independent WEBICC Nodes into a scalable enterprise architecture.
WEBICC Enterprise Architecture extends the standard WEBICC platform beyond the limits of a single SCADA server. Instead of building one large monolithic application, enterprise systems are composed of multiple independent WEBICC Nodes, each responsible for a dedicated plant, geographical area or industrial process.
This modular approach provides higher scalability, improved reliability and simplified maintenance while preserving the flexibility of the WEBICC platform.
Why Enterprise Architecture?
Large infrastructures such as water distribution networks, wastewater systems, energy monitoring, oil & gas facilities or multi-plant manufacturing rarely operate as a single centralized SCADA.
As projects grow, a traditional monolithic architecture becomes increasingly difficult to expand, maintain and troubleshoot.
WEBICC Enterprise Architecture solves this challenge through distributed WEBICC Nodes.
What is a WEBICC Node?
A WEBICC Node is a complete and independent SCADA application containing its own:
Engineering Environment
Runtime
Communication Drivers
Historian
Alarm Management
Reporting
Web Server
Local Database
Each Node operates independently and can continue functioning even if another Node becomes unavailable.
WEBICC Cluster
Multiple WEBICC Nodes can be deployed on the same physical server.
Example:
Industrial Server
• WEBICC Node – Water Distribution
• WEBICC Node – Wastewater
• WEBICC Node – Energy Monitoring
• WEBICC Node – Building Automation
Each Node maintains its own database, historian, alarms and engineering project while sharing the same hardware resources.
Benefits:
Reduced hardware costs
Independent maintenance
Fault isolation
Simplified upgrades
Flexible resource allocation
WEBICC Federation
Multiple WEBICC Nodes or Clusters may be geographically distributed.
Example:
Water North -> Water South -> Wastewater -> Energy -> Headquarters
Each installation remains autonomous while participating in a unified enterprise SCADA architecture.
Deployment Options
WEBICC Enterprise supports multiple deployment models.
• Multiple Nodes on one Industrial PC
• Multiple Virtual Machines
• Multiple Physical Servers
• Hybrid Architectures
• Cloud Deployment
The architecture can evolve as the project grows without redesigning the existing system.
Distributed Historians
Each WEBICC Node stores process data locally.
Advantages:
Maximum performance
Independent operation
Reduced network traffic
Fault isolation
Local maintenance
There is no single historian representing a single point of failure.
Central Reporting
Although each Node maintains its own historian, historical information can be exported to a centralized reporting database using:
ODBC
Node-RED
SQL
WebAPI
The central database is intended for:
KPI calculations
Production reports
Energy reports
Alarm statistics
Corporate dashboards
Process data remains local to each WEBICC Node.
Alarm Management Philosophy
Each WEBICC Node is responsible for its own alarm processing.
Alarm acknowledgement should always be performed locally by the operator responsible for that process area.
This approach provides:
Clear operator responsibility
Reliable audit trail
Independent operation
Simplified architecture
Alarm events can be exported to a centralized database for reporting and statistical analysis, while real-time alarm handling remains local.
Unified Operator Experience
Although WEBICC Nodes are independent, operators can monitor the entire system from a central dashboard.
Typical implementations include:
Enterprise overview pages
Geographic dashboards
Embedded Node alarm pages
Plant navigation
Global KPIs
The operator experiences a unified system while each WEBICC Node continues operating independently.
Fault Isolation
A failure affecting one WEBICC Node does not impact the remaining Nodes.
Benefits:
Higher availability
Easier troubleshooting
Reduced maintenance windows
Independent upgrades
Scalability
Need additional capacity?
- Simply deploy another WEBICC Node.
- No migration of the existing application.
- No redesign of the architecture.
- No interruption of other Nodes.
- The enterprise architecture grows naturally together with the customer’s infrastructure.
