© Siemens AG 2015 Weighing Electronics SIWAREX - PLC-based weighing electronics SIWAREX FTA ■ Overview ■ Application The SIWAREX FTA weighing module is the optimum solution wherever high demands are placed on accuracy and speed. Thanks to its outstanding measuring properties, weights can be measured with extreme accuracy in up to three ranges. SIWAREX FTA can be used to design legal-for-trade dosing systems, such as filling plants, loading stations, bagging stations, rotopackers, mixers or test stations. 2 Typical fields of application include: • Filling of liquids • Bagging of solid matter (also big bag) • Proportioning as deduction weighing or fill weighing • Checking of individual quantities • Loading or receiving of materials • Static checkweigher • Check weigher (in combination with Wipotec load cells) The SIWAREX FTA (Flexible Technology, Automatic Weighing Instrument) is a versatile and flexible weighing module for industrial use. It can be used in both non-automatic and automatic weighing operation, for example the production of mixtures, and for filling, loading, monitoring and bag filling. ■ Design It has the corresponding scale approvals and is also suitable for legal-for-trade weighing systems. The SIWAREX FTA is a function module of the SIMATIC S7-300 and can be snapped directly onto the SIMATIC S7-300 or ET 200M backplane bus. The installation/cabling requirements of the 80-mm wide weighing module are extremely low as a result of the DIN rail assembly and snap-on technique. The SIWAREX FTA function module is integrated in SIMATIC S7/PCS7, and uses the features of this modern automation system, such as integrated communication, diagnostics and configuration tools. A standard 40-pin front plug is used to connect the load cells, the RS 485 serial interface, the analog output and the digital inputs/outputs, a 9-pin Sub-D plug to connect the PC (RS 232), and a separate 2-pin plug to connect the power supply. ■ Benefits SIWAREX FTA is characterized by the following features: • Uniform design, and totally integrated communication in SIMATIC S7 and SIMATIC PCS 7 • Standardized configuration with SIMATIC • Direct use in the SIMATIC automation system • Use in the distributed plant concept through the connection to PROFIBUS DP/PROFINET via ET 200M • Measurement of weight or force with high resolution of 16 million intervals • High accuracy 3 x 6 000d, legal-for-trade high accuracy • Use with analog strain-gage load cells of types SIWAREX R and SIWAREX WL200 • Alternative option of connecting individual load cells from the manufacturers METTLER TOLEDO, Wipotec and PESA • Legal-for-trade display with SIMATIC standard operator panels • Stepless or stepped dosing control • Exact switching of dosing signals (< 1 ms) • Parameterizable inputs and outputs • Parameterizable for highly versatile applications • Flexible adaptation to different requirements with SIMATIC • Simple adjustment of scale using the SIWATOOL FTA program • Theoretical adjustment without adjustment weights • Replacement of module without renewed adjustment of scale • Recording of the weighing process • Legal-for-trade alibi memory • Can be used in Ex applications 2/54 Siemens WT 10 · 2014 Operation of the SIWAREX FTA in SIMATIC means that complete integration of the weighing technology into the automation system is guaranteed. ■ Function The main tasks of the SIWAREX FTA are the high-precision measurement of the current weight in up to three measuring ranges, and exact control of the weighing procedures. The weighing module controls the weighing procedures fully automatically. However, integration in SIMATIC means that it is also possible to directly influence the weighing procedures using a PLC program. This means that the tasks can be sensibly divided: the very fast weighing functions are implemented in the SIWAREX FTA , the interlocking and logic functions in the SIMATIC CPU. © Siemens AG 2015 Weighing Electronics SIWAREX - PLC-based weighing electronics SIWAREX FTA Weighing functions The SIWAREX FTA is easy to parameterize according to the various automatic weighing functions. The following weighing functions can be parameterized: • NSW (Non Automatic Weighing Instrument) according to OIML R76 • SWA (Automatic Gravimetric Filling Instrument) according to OIML R61 • SWE (Automatic Catchweighing Instrument) according to OIML R51 • SWT (Discontinuous Totalizing Automatic Weighing Instrument (Totalizing Hopper Weigher)) according to OIML R107 SIMATIC S7-400 Operator Station Engineering Station Industrial Ethernet SIMATIC S7-400 SIMATIC S7/SIMATIC PCS 7 SIWAREX FTA Monitoring and control of the load cell signals and statuses During the weighing procedure, the SIWAREX FTA weighing module monitors and controls the load cell signals and statuses. The optimized exchange of data within SIMATIC permits direct evaluation of the load cell signals and statuses in the PLC program. Influencing of the weighing sequences by the PLC means that the SIWAREX FTA can be easily adapted to any modifications in system technology. The SIWAREX FTA is already factory-calibrated. This means that the theoretical adjustment of the scale is possible without adjustment weights, and that modules can be replaced without readjustment of the scale. When using "active bus modules", replacement is also possible during operation. Integration in SIMATIC SIWAREX FTA is completely integrated into the SIMATIC S7 and SIMATIC PCS 7. Users can freely configure their automation solution – including the weighing application. The right combination of SIMATIC components can produce optimum solutions for small, medium-size and large plants. The scales are operated and monitored using SIMATIC standard operator panels. These operator panels (also touch panels such as the TP177B) can also be simultaneously used for the operation and monitoring of the plant. Customized or sector-specific solutions can be developed extremely quickly using the configuration package and example applications for SIMATIC. The following Figure shows a typical configuration of a medium-size plant. PROFIBUS DP SIWAREX in ET 200M SIWAREX in ET 200M SIWAREX in SIMATIC S7-300 SIMATIC S7/PCS 7 configuration with SIWAREX FTA Software SIWATOOL FTA commissioning software SIWATOOL FTA is a special program for commissioning and servicing and runs with Windows operating systems. The program enables the scales to be set without the need for prior knowledge of the automation system. When servicing, the technician can use a PC to analyze and test the procedures in the scale. Reading out the diagnostics buffer from the SIWAREX FTA is extremely helpful when analyzing events. The following are just some of the tasks that can be carried out using SIWATOOL FTA: • Parameterization and adjustment of the scale • Testing of scale properties • Saving and printing scale data • Recording and analysis of weighing sequence The ready-to-use function blocks for the automation system and the faceplates for the operator station are used for the configuration in SIMATIC PCS 7.

Answering just a few questions approximately presets the parameters. It is also extremely helpful to analyze the diagnostics buffer which can be saved together with the parameters following reading out from the module. 2 ■ Technical specifications SIWAREX FTA Use in automation systems S7-300 Directly or through ET 200M S7-400 (H) Through ET 200M PCS 7 (H) Through ET 200M The SIWAREX FTA weighing module includes a trace mode for optimization of weighing sequences.
