"Their results show that substantial energy savings are indeed realizable and I am now convinced that PROFIenergy will become an important enabling technology for energy management in the very near future."
Welcome to PROFINEWS! We have just held another highly successful PI Conference here in Germany and I am delighted to report that over 250 people attended, an indication of the increasing importance attached to our twin technologies PROFIBUS and PROFINET! The Conference was entitled 'Automation and Energy Efficiency' and I was particularly pleased to see that our new PROFIenergy profile is now being piloted in real applications. We also heard from one of our Institutes here in Germany (AIT from FH Cologne) about an energy audit of some real plants. Their results show that substantial energy savings are indeed realizable and I am now convinced that PROFIenergy will become an important enabling technology for energy management in the very near future. It was also a pleasure to see end user presentations that confirm the growing market success of PROFINET, also to see that PROFIBUS continues its apparently unstoppable progress. There's more about all these topics below, with much more besides. Enjoy!
Jörg Freitag, PI Chairman
he 2011 PI Conference took place in Karlsruhe, Germany, in February. Entitled 'Automation and Energy Efficiency', the keynote address was delivered by Dr. Klaus Töpfer (right), who set the scene with a speech about energy in the modern world. The first afternoon focused on PI's unique PROFIenergy profile which allows automation devices to be managed for optimum energy efficiency over a PROFINET network. Energy efficiency cropped up in many of the presentations, which included three end user experiences based on the automotive (AUDI), process (BASF) and mechanical handling (J A Becker) industries. The conference included two Podium Discussions - one on energy efficiency in automation and the other on Ethernet in process automation - and a series of parallel sessions covering all aspects of PROFINET and PROFIBUS, including wireless and safety.

There's still time to take part in our survey about PROFINET. Help us understand what PROFINET means to you and your markets and you could win an iPod Nano, an iPod Shuffle or a free copy of Manfred Popp's excellent book 'Industrial Communication with PROFINET'!
Most of the drives are connected via PROFIBUS and PROFINET in nine cabinet locations. Failsafe signals are transferred via PROFINET too. Since all drives and HMI devices are integrated in the same system all nodes in the system can be accessed from any location. The control system knows the exact target position of the elevator and also the velocities to run. The PLC calculates the deceleration ramps while fixed sensors check the elevator’s position. The monitor system is double redundant: one system control the positions and one system watches the position monitoring system. Faster operating speeds and softer decelerations are now possible. Using wireless PROFINET solves all problems at once, say staff at Liseberg. Further, the level of safety they now have with PROFIBUS and PROFINET is far superior to that of previous systems.
Eighteen free training classes have been scheduled for 2011, based on PROFIBUS and PROFINET technologies. 
The Japanese PROFIBUS Organization (JPO) attended the SEMICON Japan Fair in December 2010 in Chiba, near Tokyo. SEMICON is the semiconductor industry exhibition and it attracted about 66,000 visitors. JPO has participated for the last 9 years and customers recognize and respect the long lifetime of PROFIBUS and the continuous promotion activities of JPO. With the cooperation of 16 member companies, JPO presented a demonstration comprising 35 PROFIBUS and PROFINET devices. Experts from these companies also supported the booth to meet visitors and answer questions. 
These new PROFIBUS DP connectors have a D-Sub and M12 interface with 35°, 90° or 180° cable outlets. All versions support data rates of up to 12 Mbit/s and feature compact die-cast zinc housings with test socket and active terminating resistor. They also boast quick-connection technology that needs no tools. The 9-pole D-Sub interfaces of the male and female connectors can connect high-level control systems, decentralized I/O stations, programming units or diagnostic devices. The B-coded M12 interfaces serve as a PROFIBUS input or output and signals can be daisy-chained via the output. 
Leuze’s newest barcode reader in the BCL500 family includes a PROFINET port. Claimed as a a 'world first' it's fully configurable over the network to give faster setup and the ability to hot-swap a damaged reader. A choice of protocols provides quick and easy implementation and an integrated web-server is also provided. All BCL500 types include barcode reconstruction technology which can rebuild a barcode from partial codes from multiple scans, making it able to read damaged codes. 
This hand-held IO-Link EMC Tester tests IO-Link Master and Devices. It counts erroneous and missing telegrams. Different IO-Link output stages may be plugged in dependent on whether a Device or a Master is being tested. Operating state, error counters and baud rates are displayed via LED and LCD displays. Battery operation is possible, or an external 24V source can be used. 
Cube67+ modules are now available with PROFINET connectivity. Up to two x 32 modules can be connected to just one bus node. Installations can cover long distances since cable lengths of up to two x 30 meters can be implemented. Cube67 modules can be installed at any position along the cable and the energy supply can be daisy-chained at the bus node. Integrated electronics check the outgoing system for short-circuits and overloads. If an M12 connector is under excessive load an early warning is given; if a limit is exceeded the line is switched off. Diagnostic messages are then sent to the control device.
