Fast and no-code development of web-based operator interfaces


Operations Hub developed by GE Digital is a summary and display tool for industrial applications that combine quick application development with detailed visualizations. The system supports improved decision-making and shorter response times in the case of process or requirement changes with simple configuration options.

Operations Hub enables system integrators and in-house engineering teams to use high performance, no-code development tools to build web-based applications that can be connected to GE Digital software and other typical Industry 4.0 data sources such as databases and other control systems. No-code tools facilities the inclusion of multiple non- developer users in the creation of customized visualizations at the same time. This accelerates development and helps to lower costs.

The system provides connectors to various data sources. It also provides storage capacities for the data necessary for initial analysis and visualizations. This enables organizations to gain a unique insight into process flows and the details of production. This in turn is an essential step on the path towards digital transformation.

Accelerated development of advanced web applications

In order to facilitate the implementation of responsive operator visualizations Operations Hub provides a collection of pre-defined and pre-configured control elements to enable non-developer contributors to quickly create and design visualizations. Data sources and entities of the connected devices can be easily defined and converted to actionable information using data query capabilities. The drag and drop interface of visualizations enables easy planning and configuration of visual elements. To create a data connection all you need to do is to configure a query or a data source for the respective element.



  • Visualization and fast development of web-based manufacturing parameters
  • Centralized visualization ensures faster response time and informed decisions
  • Lower cost and shorter market introduction time of web-based operational application development
  • Lower maintenance costs of centralized web applications
  • Information is available anytime and anywhere due to responsive design


Instant access to information


Responsive design helps to create applications that can display information on a PC, tablet, or smart phone, giving access to production data and manufacturing parameters anytime and anywhere.

Actionable information collection and visualization

You can use the predefined control element collection to easily create charts, tables, diagrams, figures, videos, maps and so on. Operations Hub also offers manual data entry control elements for user input to execute operations and return data and commands to the connected sites. Operators can open additional data related interfaces, modify context and manually input data.

Operations Hub enables everyone to build web-based applications using no-code development tools.

Save time with ready to use clients and centralized administration

Using web technology, Operations Hub enables you to save time on deployment and maintenance. Truly native web clients do not require installation. Deployment and maintenance have never been this simple.

A quick, automatic response

Operations Hub enables you to create automatized actions based on human or machine data. You can configure actions to query data or send emails or commands to devices connected to the system.

  • A user friendly interface with a rich predefined object library for developers
  • Automatized operations based on the data stored in a common database
  • Event-based operations: Send emails (including templates), run queries and send commands to devices
  • Create entities and queries for relational databases
  • The use of HTML5 and CSS3 languages ensures platform independence
  • Applications are available on a PC and on mobile devices
  • Application and data access control based on user roles
  • Query types: Get, update, insert, delete
