AVENTICS offers direct added value for your IoT concept, with smart components that integrate seamlessly into a digital environment thanks to on-board intelligence and compliance with all relevant communication standards. Our solutions focus on the flexible further use of the generated information. Local evaluation and storage in the component, in a local database, in a private or public cloud – all options are covered.
Want to check the state of wear? Need information on energy efficiency? The new Smart Pneumatics Monitor will provide you with reliable answers. It sends status messages to defined employees and parent IT systems without detouring to the machine controller. This minimizes the risk of machine downtime and substantially lowers operating costs.
Together with our AES fieldbus solution, the Smart Pneumatics Monitor (SPM) IoT gateway analyzes existing sensor signals and uses the result to generate status information. To monitor the wear of a shock absorber, for example, the SPM breaks down the end switch signals to evaluate the cushioning sequence. Algorithms written by AVENTICS based on the company’s application experience analyze this data internally and send the information either to defined people or to the parent MES or ERP systems via the OPC UA interface.
The SPM makes it easy for AVENTICS customers who are already using AV valves and the AES fieldbus system to take a further step towards implementing IoT solutions. Programming of the SPM can even be edited while the application is running, without any impact on communication to the controller.
SPM basic equipment and connections
The four SPM applications listed below are characteristic examples that illustrate this innovative IoT gateway's simple operation, its great flexibility and outstanding efficiency.
The shock absorber in this configuration had been replaced in
regular routine intervals determined on the basis of past experience with the individual application – purely as a precautionary measure and not based on actual facts. The SPM now uses the cylinder sensor data to analyze the cushioning's timing characteristics.
Because cushioning time decreases over the service life of the shock absorber, it provides direct proof of its state of wear. As soon as a critical value is reached, an error message can be output to exchange the shock absorber before it fails.
A valve's state of wear is very difficult to determine from the outside but additional internal sensors would increase its size and add to costs. In contrast, the SPM is able to provide information on the expected service life of the valves – without incurring additional costs and effort. By measuring the valve's exact switching cycles it is possible to extrapolate the end of its typical service life. Preventive maintenance can then be carried out to avoid downtimes in critical applications.
Energy efficiency is a key economic factor. The SPM gives a clear indication of where and how compressed air consumption changes – and allows users to determine the location of possible leakages. Predictive diagnostics is one of the main arguments for efficient use of the SPM.
In this example:
Increase in consumption only when valve is actuated -> Anomaly/leakage on or downstream of valve
Overall increase in consumption -> Anomaly/leakage in supply or upstream of valve
Whether during initial configuration or to improve ongoing operation: An optimum compressed air level saves money and prevents wear on the components. An SPM analysis helps you to determine the optimal operating point for a perfect balanceof the work to be carried out and the supplied energy.
In this example:
The preset pilot pressure is reduced gradually and the impact on compressed air consumption and cycle time is monitored to determine the operating point where the cycle time can be maintained with the least energy consumption.
