The PROFIBUS-PA is normally connected to a segment coupler which, among other things, carries out conversion to the PROFIBUS-DP. Here, it needs to be noted in particular that the segment coupler is normally set to a fixed baud rate on the DP side. Further information on the planning and operation of PROFIBUS-PA networks is to be found in the KROHNE brochure)PROFIBUS-PA networksi. KR O H N E KROHNE Messtechnik GmbH&Co. KG JILudwig-Kroh ne-Str.5• D-47058 Duisburg 3/7 Tel.:0203-301 309• Fax:0203-301389 je-mail:krohne@krohne.de Supplementary Documentation IFC 090, IFC 090 i with PROFIBUS-PA 1.1 GSD All available GSD files of KROHNE devices n including those of the IFC 090, of course - are supplied together with each device. The GSD contains information that is needed for project planning of the PROFIBUS-DP/PA communication network. The relevant data files must be loaded into the project planning system/master system before start-up of the bus system. For example, the following applies to COMET 200 or COM PROFIBUS from Siemens: oc all GSD files (*.GSD) into the directory of the GSD files, e.g. *\GSD oc all BMP files (*.BMP) into the directory of the bit maps, e.g. *\BITMAPS In STEP7, the GSD file is automatically copied into the respective directory with iinstall new GSDi (in the HW-Config Menu: EXTRAS). After that, the bit map must be copied into the directory *\SIEMENS\STEP7\S7data\Nsbmp. Following icatalog updatingi the device can be placed in the project. This will then enable the cyclic communication (measured values and status). 1.2 PROFIBUS-PA profile The IFC 090 supports the PROFIBUS-PA Profile Version 2.0. Additionally, all relevant parameters in the device are offered via the PROFIBUS-PA interface. The IFC 090 defines the following blocks: oc Three Function Blocks (FB): One Analog Input-FB for flow and two Totalizer-FBs for totalizers. During configuration of the network you can distinguish between two different kind of totalizers. First the temporary Profibus totalizers (PA-Tot.1/2) which will be resetted after power on. These totalizers are according Profil 2.0. You also can choose the permanently stored device totalizers (Device-Tot.1/2). These device totalizers will be mapped to the totalizer function blocks whereas limits and the unit of this block can be used together with the device totalizers. Reset function is possible as well. 00 One transducer block for electromagnetic flow measurement. This block provides the parameters defined in Profile 2.0. 00 One physical block. This block contains the parameters defined in Profile 2.0, and also all device-specific parameters in the form of an appendix. 1.3 Meaning of measurement and status information During integration of the KROHNE device into the PROFIBUS master you can choose which values should be transfered via PROFIBUS. This can be done by using the GSD file. Each value which is a 4 Byte Float Format according IEEE Standard 754 Short Real Number a status byte follows. That means each measurement value consists of 4 byte value plus 1 byte status. Other measurement values will directly follow as 5 Byte pakage if configured during integration. Below the meaning of the status byte is described: Float Format Byte n Byte n+l Byte n+2 Byte n+3 Bit?Bit6 Bit?Bit6 Bit?

Electrical connection (see Section 2 in the Installation and Operating Instructions) 2.1 Interconnection of devices in the hazardous location We recommend that a PROFIBUS-PA network in the hazardous location be projected in accordance with PTBis FISCO model (see KROHNE brochure iPROFIBUS-PA networksi). The FISCO-Model may be used, if: all electrical components which should be connected to the bus must be approved according the FISCO model (even the termination), the maximum cable length does not exceed 1000 m, the values of the cable are within the following ranges RY=15...150 /km; LY=0,4...1 mH/km; CY=80...200nF/km, the approved input values of the field devices (Uo, Io, Po) are matchable with the output values of the power supply (e.g. segmment coupler) which menas Ui Uo, Ii Io and Pi Po. 2.2 Bus cable Further limitations to the cable than the FISCO limitations are not existent. Nevertheless a twisted pair and shielded cable is strongly recommended. The good quality cable could have the following data: 44 /km, <90nF/km, <3dB attenuation at 39kHz and 100 Ohm impedance at 31,25kHz. 2.3 Shielding and grounding For optimum electromagnetic compatibility of systems it is extremely important that the system components, and particularly the bus cables connecting the components, be shielded and that such shields - if possible - form an unbroken cover, electrically speaking. Hence it follows that, for use in non-hazardous duty systems , the cable shield should be grounded as often as possible. In iExi systems an adequate equipotential bonding in the hazardous and non-hazardous location along the entire fieldbus installation is strongly recommended. Multiple grounding of the shield is also of advantage. Note: The use of twisted and shielded cables is strongly recommended, otherwise EMC protection of the IFC 090 cannot be assured. 2.4 PROFIBUS-PA connection Connect the bus cable as shown in the figure. oo Connect the cable cores to terminals D and D co The cable shield should be connected with 00 Polarity reversal will not have any effect. minimum length to the FE functional ground. oc The equipotential bonding conductor must be connected to the device by connecting it to FE functional ground.
