7MH4930-0AA01 Siemens weighing module Product description SIWAREX MS WEIGHING ELECTRONIC FOR CONNECTING ONE SCALE. FOR SIMATIC S7-200 / RS232-INTERFACE FOR CONNECTION OF A PC, TTY- INTERFACE FOR REMOTE DISPLAY SIWAREX MS is a versatile weighing module called Heavy module for all simple weighing and force measurement tasks. This compact module can be a convenient way to install into SIMATIC S7-200 automation system. The current weight data directly accessible in SIMATIC-CPU, the need to add other interfaces. SIWAREX MS weighing module has the following main advantages: 1. standardized installation technology, weighing module in SIMATIC S7-200 systems continuous communication 2. Use STEP 7-Micro / WIN unified design 3. Weight and force measurement internal resolution of 65,000 points, accuracy is 0.05% 4. Use of prefabricated software "Getting started" You can use a simple program designed to 5. SIWATOOL MS via RS 232 interface is very easy to set up for electronic scales 6. Even without calibration block, but also the theoretical calibration 7. replace the module without having to re-calibrate the use of electronic scales 8. Ex interface, an area intrinsically safe weighing sensor power supply can be installed in Ex zone 2 9. direct a remote indication Connect the TTY interface Siemens Siwarex weighing module is directly integrated with a weighing function in S7-200 and S7-300 PLC in the expansion module. With increasing levels of automation, PLC automatic control technology in the production of prepackaged applications, more and more food, fertilizer, feed and light industry and other industries are widely used. Compared with the traditional weighing instrument control, integrated Siwarex weighing module S7-200 or 300PLC weighing and control functions can be the perfect combination, to achieve high-speed and high-precision weighing packaging applications. Siwarex MS weighing weighing module has all the features, including automatic zero and calibration functions, both the temperature and the load cell excitation voltage compensation. Weight data can be fed directly into the S7 PLC CPU. 2. Weighing Packaging Machine Works 2.1 composition weighing packaging machine automatic packing machine by feeding part, discharging part weighing control parts. The feed section is divided into hopper and gravity feed device. Material hopper for storage needs filling, gravity feed system is to provide the material to the weighing hopper. That is weighing hopper weighing part, it is connected through and weighing sensors measure the weight of the material. Discharge portion for discharging the bagging process is completed standard weights of the materials (Figure 1). 2.2 weighing control system configuration according to the operation and control requirements quantitative automatic weighing packaging machine control system using SIMATICS7-200 series PLC, and expand two Siwarex MS weighing module, consisting of one pair of weighing bucket packaging systems. Motion weighing packaging machine system by feeding door S7200 PLC control, load cell signal through MS weighing module converts weight value. Comes with a text display for the entire system, including the weighing hopper packing machine process monitoring display, calibration and parameter setting functions. Setting target weight filling large feeding amount, small to quantity, while real-time monitoring weighed, and view the filling data. And at the same time as the scales bucket operation display interface, to achieve zero, calibration data, and various settings and display scales. PPI load cell weighing sensor TD400C CPU226 MS MS 2 and can use a variety of communication interfaces s7-200PLC, including Profibus DP, Ethernet and other networking functions to achieve a variety of communication. 2.3 Working principle and process quantitative automatic weighing packaging machine works flowchart (Figure 2). When the material hopper enough, under the action of gravity into the gravity feed system, fully open the door into the large feed material state. When you reach a given large feeding weight, reduce the feed door opening, into the small feeding state. When you reach a given weight of a small feed, the feed door is completely closed, after a certain amount of air blanking, weighing hopper stable, and when the card bag clamping mechanism, the discharge door open, put the material into the hopper, and then fall into the bag inside, a complete packing cycle. Weighing module controls the flow chart in Figure 2 3.

Siwarex weighing module system characteristics and advantages 1. System reliability Siwarex MS weighing module is integrated directly in the S7-200 systems connected via PLC backplane communications. Between weighing and PLC without additional wiring and communications conversion; 2. High precision due to the Siwarex MS weighing module with a load cell excitation voltage and temperature compensation, high accuracy, while the PLC program can be programmed according to the material properties, making packaging machine with higher precision packaging; 3. fast weight signal directly into the CPU, no secondary conversion, the reaction rate and improve the control precision PLC control system. 4. Easy maintenance due to the reduction of conventional hard-wired weighing controller and PLC, the middle part of a small, high-quality hardware. So that the system can achieve higher reliability. The modular design also easier to install and replace. 5. Each S7-224xp flexible system architecture can be accessed by four MS module, S7-226CPU 7 MS module can be accessed. Each scale can also be called a variety of materials, reducing system cost. 6. easy configuration of standard software programming library, just a direct call, you can achieve all kinds of weighing control functions; special shelf Siemens weighing module 7MH4930-0AA01 7MH4950-1AA01 7MH4950-2AA01 7MH4900-2AA01 7MH4900-3AA01 7MH4910- 0AA01 7MH4553-1AA41 1, Siemens S7-200CN full range of products available ex stock following: TD400: 6AV6640-0AA00-0AX0, Smart 700ie 7 ": 6AV6648-0BC11-3AX0 Smart 1000ie 10.2": 6AV6648-0BE11-3AX0 Siemens weighing module : 7MH4930-0AA01 7MH4950-1AA01 7MH4950-2AA01 7MH4900-2AA01 7MH4900-3AA01 Siemens ultrasonic level sensor: 7ML1201-1EE00 7ML1201-1EF00 Siemens modules: 6ES7232-0HD22-0XA0 6ES7231-7PF22-0XA0 6ES7231-7PC22-0XA0 6ES7231-0HF22- 0XA0 6GK7243-1EX01-0XE0 Siemens encoder: 1XP8001-1 / 1024 Siemens programming cable: 6ES7972-0CB20-0XA0 discontinued alternative 6GK1571-0BA00-0AA0 Siemens converter: 6SE6420 / 6430/6440 (MM4 series) P + F encoder and Sensor Inventory: DVM58N-011AGR0BN-1213 FVS58N-011K2R3GN-0013 RHI90N-0HAK1R61N-01024 UC2000-30GM-IUR2-V15 RVI50P-09BALA3TN-01000 UC4000-30GM-IUR2-V15 RVI58N-011K1R61N-01024 UC500-30GM-IUR2-V15 2 , Wei Lun touch screen: MT6070 / TK6070 whole series!
