platform EDIP Ef ficient Device Integration Platform from Bürkert offers a efficient way to integrate several sensor actuator mo dules such as the new Mass Flow Con trollers or Meters of the 874X series into an Industrial Ethernet network using a superordinate system control unit Bürkert has eliminated control related elements for the new Type 8741 Mass Flow Controller MFC Mass Flow Meter MFM These con trol tasks are assumed by a superor dinate control unit which addresses sensor actuator modules such as Mass Flow Controllers by means of a system bus The MFCs MFMs are equipped with an interface for the proprietary Bürkert System Bus büS Previously each MFC MFM included its own con trol hardware now the Type ME2X system control unit SCU is used The SCU can control up to 16 control cir cuits at once and functions as a gate way between Industrial Ethernet and the büS Figure 9 As a result the field device level can be connected directly to Industrial Ethernet in a effective manner büS is based on CANopen however it works with auto addres sing and without a master in the sys tem If a CAN bus is already present in the customer application switching between büS and CANopen is possi ble with a DIP switch on the device The shift of the control hardware from the MFC MFM to the SCU results in considerable benefits in applications with numerous control loops Both the simplified flow controllers meters and reduction to only one Ethernet inter face in the central control unit con tributes to easy implementation and high efficiency of the plant Type 8741 is equipped with MEMS technology for direct flow rate measu rement in gases and designed for flow rates from 0 01 Nl min to 80 Nl min referring to nitrogen The MFCs MFMs convince with high accuracy quick response times and excellent re peatability In the process it achieves very short settling times All Type 8741 devices are enclosed in a sturdy poly carbonate housing which is seated on the fluid aluminium or stainless steel body The 4 pin terminal block ensures easy electrical connection The Type ME2X system control unit SCU has a modular design The gateway mo dule ME23 is mounted together with the büS input and büS output modu les ME29 on a joint backplane which permits top hat rail mounting Type ME24 I O modules can be optional ly integrated in the SCU Two RJ45 plug connectors establish the Ether net connection and a mini USB port is provided for factory service The parameterisation and diagnosis of the components takes place with the Bürkert Communicator software and the büS stick which is available as an accessory As part of the new EDIP device platform this enables conve nient process control A highlight is the User f x function which can be started from the Bürkert Communi cator The User f x enables fast and simple programming of customised system controls Signals read by the SCU e g from an ME24 I O module can also be processed A well known example for use of such a controller is the adjustment of gas mixtures Bür kert s Mass Flow Controllers MFC for gases are used in industrial proces ses such as the production of metal or glass components where gases which are usually inert reactive or flamma ble must be dosed with a high level of accuracy and repeatability An over all system comprised of an SCU and the new compact MFCs is a convin cing package with efficient Ethernet connection and simple but powerful integrated software Press Release March 2015 JÖST at GIFA and METEC As lead ing manufacturer of vibrating ma chines and system solutions for the foundry industry JÖST GmbH Co KG presents an interesting products overview for primary and secondary metallurgy Our scope of supply re fers to the conveying of raw materi als screening storage and dosing of different products up to the different furnace melting processes like EAF RH VD or LF We would like to in vite you to our Stand F33 in Hall 3 to discuss innovative solutions for your requirements and to introduce us as your competent allround partner At the same time we are present at the GIFA Hall 17D47 showing new tech nologies designs and complete solu tions partially in operation Press Re lease April 2015 Siempelkamp Order for two isother mal forging presses Leistritz Turbinen technik GmbH ordered from Siempel kamp the design and supply of two 8 MN isothermal forging plants for the manufacture of turbine blades made of titanium aluminide The customer will use these forging presses to manufactu re a new generation of aircraft engines which are compared to the nickel base alloys currently used up to 50 lighter while offering the same strength Thus they allow for significantly reduced fuel consumption Due to its interme tallic structure titanium aluminide is characterized by its high strength and excellent creep resistance at high tem peratures At the same time at a densi ty of 4 g cm3 it is very light Therefore Fig 9 büS system consisting of four Mass Flow Controllers Type 8741 with sys tem control unit Type ME2X for In dustrial Ethernet connection
