Wonderware System Platform is an industrial automation software suite by AVEVA (formerly Invensys), providing a scalable, unified environment for HMI, SCADA, MES, and IIoT applications. It enables centralized configuration, real-time monitoring, and integration across diverse industrial assets.
Primary Use Cases
- ▸Supervisory control and monitoring
- ▸HMI and SCADA visualization
- ▸Data historian and reporting
- ▸MES and production monitoring
- ▸IoT/IIoT integration with analytics and dashboards
Notable Features
- ▸Object-oriented template-based application development
- ▸Centralized management of HMI, alarms, and historian data
- ▸Scalable architecture for single-site or multi-site deployments
- ▸Integration with PLCs, databases, and enterprise systems
- ▸Support for redundancy, failover, and high availability
Origin & Creator
Wonderware System Platform was developed by Wonderware (now part of AVEVA) in the early 1990s as an advanced HMI/SCADA framework for industrial automation and process management.
Industrial Note
System Platform provides high-level abstraction for industrial applications, allowing standardized object templates, centralized configuration, and scalable deployment across multiple sites and operations.
