So that it runs optimally

Furthermore, peak loads can be controlled and avoided, which leads to a further reduction in energy costs. In addition to energy consumption, IIoT gateways can also monitor other resources, such as lubricants and spare parts. By closely monitoring resource consumption, companies are able to avoid it and prevent waste. This not only helps to reduce costs, but also optimizes the sustainability and environmental compatibility of production processes.

Interface between IT and OT

Phoenix Contact has developed an open, scalable and flexible software solution for the applications described. The IIoT framework is based on PLCnext Technology and is compatible with all controllers in the PLCnext Control product family. It acts as an interface between Operational Technology (OT) and Information Technology (IT) and allows seamless integration and communication between the levels. To this end, the IIoT framework provides both input and output connectors.

Different process data can be read in with the input connectors. Phoenix Contact offers a broad portfolio of I/O modules for recording this data. They can be used to record various sensor values such as speed, temperature or vibration as well as different transmission protocols - for example HART or Modbus/RTU. It is also possible to collect data from network components, such as energy meters, or controllers from other manufacturers. This allows operating data to be recorded and processed precisely. The output connectors of the IIoT framework send the collected data via various protocols such as MQTT, REST-API, GRPC or CSV to different destinations, such as servers, databases or cloud platforms.

Thanks to the high-performance forwarding of data, anomalies are detected at an early stage and appropriate measures are taken before major failures occur. This significantly increases the availability and reliability of the conveyor systems.

Development of own connectors

Within the IIoT framework, the data, which can be recorded deterministically and in real time, is normalized and pre-filtered. It also contains meta information such as the data source, a timestamp or the unit. This helpful contextual information significantly increases the added value of the data for subsequent evaluations and presentations. The integrated web interface of the IIoT framework enables intuitive configuration of the connectors without the need for employees to have any programming knowledge. This simplifies the implementation and use of the framework and makes it a suitable solution for companies that want to digitize and improve their conveyor technology. Thanks to ready-made system functions, the framework also makes it easy to develop your own individual connectors based on the PLCnext Engineer engineering environment. The customized adaptation of the connectors to specific requirements expands the application options of the IIoT framework from Phoenix Contact in the field of conveyor technology. The use of IIoT gateways opens up a range of benefits for the user. These contribute to optimizing the production process and increasing efficiency.

Continuous monitoring and control of the conveyor belts, improved maintenance and efficient energy and resource management enable companies to reduce their operating costs, increase plant availability and achieve their defined sustainability goals. The IIoT framework and the connectors implemented as standard are available free of charge on the PLCnext Store digital marketplace.
