Kübler
Predictive maintenance
Fritz Kübler aims to evolve from a pure component supplier into a provider of holistic IIoT solutions. To achieve this, the company offers a solution for analyzing collected data to monitor systems and machinery, as well as for predictive-maintenance evaluations.
At the core of the solution is an IIoT edge gateway with the Siineos operating system, which enables the storage, interpretation, and analysis of data directly on the device (on-premise). The IIoT edge gateway enables flexible and efficient data processing by allowing every integrated signal to be adjusted and stored in a time-series database. In addition, query and write intervals are configurable - making it possible to define how frequently values are recorded and saved for all signals. Beyond local storage, the processed signals can be transmitted to cloud systems via standardized protocols such as MQTT or OPC UA for further analysis.
The operating system also offers various apps that can be used for graphical visualization, real-time analysis, or generating alerts when defined thresholds are reached. The IIoT solution can be used either as a stand-alone system or seamlessly integrated into existing infrastructures.
Integration of the IIoT solutions into existing control and supervisory systems is carried out via standardized communication protocols to ensure maximum interoperability: The IoT protocols OPC UA, MQTT, and REST API enable integration into existing systems and connectivity to the IO-Link ecosystem. Devices with Modbus, analog, or digital interfaces can also be connected directly. Existing control and supervisory systems can be integrated via OPC UA, MQTT, Modbus, or the Siemens S7 protocol. Additionally, thanks to an SQL connector app, data can be written directly into customer databases via plug-and-play, reducing project time and cost. This ensures end-to-end communication between Kübler's IIoT solutions and third-party systems - both for on-premise and cloud architectures.
To prevent tampering and unauthorized access, Kübler employs multiple security mechanisms: The IIoT edge gateway is based on a hardened Linux system with a minimal attack surface. The Siineos operating system is continuously updated through secure update processes. An integrated user-management system allows targeted assignment of services to defined user roles. Tampering with collected condition data is impossible, as the time-series database is read-only. Overwrites occur automatically once the retention period expires. These measures ensure secure data processing at both the device and network level.
