Rising energy costs are focusing attention on more intelligent technologies that can help processors keep their energy use under control. Peter Mapleston fi nds out more


Smart solutions keep energy in check


As Industry 4.0 becomes less of a catch-phrase and more a real industrial revolution enabling truly “smart” factories, technology suppliers from across the plastics industry are using the improvements in connectivity it makes possible to provide processors with new and better ways of monitoring and controlling their energy consumption (and, of course, many of these innovations will be on show at K2016 next month). Engelbert Kastner, Software Services Manager at injection moulding technology leader Engel, explains what this means for the processing community. “In the past, a large number of developments in drive systems have helped reduce the energy consumption of individual consumers. But today, the accent is more on the intelligent distribution of energy. Rapid advances in the networking of machine pools offered by Industry 4.0 open up new opportunities,” he says. At K2016, Engel will demonstrate a new energy


module for its MES (Manufacturing Execution System) e-factory. The company says the module makes it possible to track the energy consumption of individual consumers in production with greater transparency. In addition, starting from K2016, the company’s MES will be able to automatically avoid power peaks to reduce power costs across the entire machine pool.

display, evaluation and optimisation of energy consum- ers. Machines from different manufacturers can be integrated to obtain a complete energy balance. At the same time, consumers not integrated in the MES can be recorded manually. “These functions form the basis for certifi cation according to EMAS, the European Union Eco-Management and Audit Scheme,” Engel says. An additional advantage of the new module is the


intelligent distribution of available power sources to individual consumers, the company points out. “This hall management system is particularly benefi cial when the entire machine pool is started up at once after a weekend or a factory shut-down, for example,” it says. “The dynamic allocation of machine-specifi c consump- tion limits prevents energy peaks even in these cases.” The new energy module accesses data within the


“ecobalance” energy management system incorporated in Engel’s CC300 machine controller. The system allocates specifi c consumption limits and a specifi c priority to each consumer within the machine or production cell for both machine start-up and in-pro- duction modes. For example, it takes into consideration the high power demand required by a machine during warm-up and the high demand for plasticising and injec-
