Here in Nuremberg,Vega is showing how level sensors can be operated wirelessly via Bluetooth - please outline the benefits?

Höll : With our 'plics' sensors, the 'Plicscom' display and operating module makes it easy to display, operate and diagnose measured values directly on the sensor. Bluetooth is directly integrated in other sensors. Thanks to the optional Bluetooth function, this is now also possible wirelessly from a distance of up to 25 m - with around 80 sensors now available. This means that sensors that are difficult to reach - for example in high silos, in poor weather conditions or in hazardous areas - can be safely controlled via a laptop, tablet or smartphone using a second data channel. This saves costs during commissioning and for continuous use. Already installed plics sensors can also be easily retrofitted with Bluetooth.

To what extent is I4.0 an issue for Vega?

Höll: In the area of I4.0, digitalization or the cyber-physical system, we have been setting a wide variety of priorities for several years: our sensors speak digitally, are networked with digital communication and evaluation devices and transmit the measurement and diagnostic data to the local or cloud solutions hosted by Vega. Higher-level, intelligent systems such as the 'Vega Inventory System' can already process sensor data via the digital interfaces.

What challenges do you see for I4.0 in process sensor technology?

Höll: The top priority is the security of process and analysis data; systems must not be vulnerable at any point. As digital IP communication is the standard for I4.0 at field level, manufacturer-independent standards are required - for both hardware and protocols. However, it is essential for us that, no matter how complex a technology may be internally, it must always be simple for the customer, from commissioning to analysis and maintenance.

Are the products on show at the stand I4.0-compatible?

Höll : Continuously measuring sensors with digital and the additional option of wireless communication form the basis for I4.0. This applies to all IO devices, from wired devices with an Ethernet interface to wireless variants that process signals and data via mobile radio. Here in Nuremberg, for example, we are showcasing smart, standardized operating tools for parameterization and analysis: PC-based with Pactware on the one hand and APP-based with smartphones or tablets on the other. We also rely on highly communicative software solutions for the local or hosted cloud for visualizing and monitoring fill levels, which enable connection to systems such as ERP.
