Join the Kaeser Network



Fast and secure with an eye to the future! The powerful Ethernet-based Sigma Network developed by Kaeser provides optimized compressed air system monitoring and control. Moreover, it is able to take advantage of the future-oriented benefits that Industry 4.0 and the Industrial Internet of Things (IIoT) have to offer.

Industrial applications place special demands on machine to machine communications - and this is the basis of Industry 4.0/the IIoT. The technology must not only be durable and easily manageable onsite, but should also be globally compatible, fast, secure, and able to transfer large volumes of data with maximum integrity. In addition, it should ensure the real-time capabilities required by the process. Kaeser Sigma Network meets all of these needs and more.

Secure data
Based on secure Ethernet technology, the future-ready Sigma Network is a local network within the compressed air system that enables optimized integration of a system’s components. Unlike current field-bus solutions, such as Profibus, CAN, or similar technologies that operate at relatively slow speeds (max. 12 Mbit/s), Sigma Network has a transfer speed of 100 Mbit/s. The widely accepted TCP/IP protocol standard - also recognized as the Lingua Franca of the internet – forms the basis for data traffic in the Sigma Network.

The Network uses Kaeser’s own MAC addresses and creates a closed and secure network segment in accordance with the recommendations for industrial control systems. A defined transfer node enables secure data exchange with external partners.

Basis for predictive maintenance
Sigma Network, working in perfect harmony with the Sigma Air Manager 4.0 master controller, forms an infrastructure that makes data available for future services, such as predictive maintenance, or energy management. This not only reduces costs, but also increases operational reliability and availability. If desired, operational data from the compressed air system can be securely transferred to the Kaeser Data Center via a broadband connection. This allows Kaeser experts to perform remote diagnostics and enables predictive and demand-oriented maintenance. Users therefore benefit from maximum supply dependability, as well as lowest possible life cycle costs, since Kaeser's compressed air specialists are able to adjust the energy characteristics of the compressed air station as required so that the station performs at its maximum efficiency at all times.
