The customer managed to reduce the componets in the cabinet, thanks to the Safety Integrated concept (no external safety relais required) and the use of a single, all-purpouse, fieldbus, Profinet. Less components lead to higher robustness. 
The availability has also been increased thanks to the UPS1600 with the energy storage BAT1600. The battery allows to overcome short-term voltage dips and to safely stop the machine in case of long power failures. 
Less cabling is a plus too. The Profisafe communication to the servo-drives and converters runs over the same Profinet cable as the standard communication, keeping from cabling a lot of safety terminals. The One Cable technology of the servo-drives Sinamics S210 reduces the cabling efforts too. 
Less unplanned machine downtime, thanks to the UPS, lead to a productivity increase by 5%. Performance was kept while reducing engineering and commissioning time by 20%, due to TIA Portal integration of Motion Control and Safety. Building up the machines was 20% faster than before, thanks to less cables in the machine and less components in the cabinet.
