TRUSTAR Automatic Weighing System Features
1, full integration
Totally Integrated Automation (TIA) combines highly integrated integration and unprecedented openness, a standardized network architecture, a unified programming configuration environment and highly consistent data integration for the enterprise to achieve horizontal and Vertical information integration; leading communication standards, component-based automation technology, PC automation solutions and IT integration, and the entire range of products and services in the automation market is truly open;
Fully integrated schematic:
2. PC-based human-machine interface software system
● Runtime interface with Windows Vista theme style and appearance;
● New controls: historical data trends, alarms, recipes, etc.;
● Object-based programming mode, panel technology;
● Free integration of advanced user management tools SIMATIC Logon;
● Enhanced security, support for Windows Firewall and virus scanning;

3, SIMATIC PLC control system
The TRUSTAR automatic weighing system integrated in the PLC system can directly and highly reliably complete the control of weighing-related actuators such as pump valves, and integrates with the automation system of the entire plant through communication methods such as PROFIBUS and Ethernet to reduce field wiring. Reduce system failure rate, increase system flexibility and improve system response. The automatic weighing processing module and the I/O control module can be expanded according to the number of on-site scales and the equipment to be controlled, thereby avoiding the limitations of the control functions of the conventional weighing control instruments (secondary tables, etc.);
4. SIWAREX weighing electronic module directly integrated into the PLC system as a function module
It can be used for various SIMATIC solutions, whether it is integrated in the S7 programmable controller as a module or as a distributed I/O with SIMATIC S7 or C7.
No need for any additional coupling module for direct integration, so system integration costs are low
● Adopt unified system concept and low configuration cost
● System-compatible module response (diagnostics interrupt, command output inhibit, etc.)
● Expansion with standard SIMATIC components, special low-cost weighing systems
● High utilization rate
● Easy to install with snap-in technology
● Compact design, low space requirements
Field Application
Whether it is a large range of weighing or weighing in hazardous areas, we have a complete solution
100T load cell and mounting unit Intrinsically safe sensor in hazardous area
Explosion-proof safety barriers applied in the field Siwarex weighing electronic modules integrated in the total PLC system
Typical Case
In Nanjing Jinpu Jinhu Chemicals, in order to ensure the efficient operation of the factory and product quality, the production process must be optimized and highly automated, and the user adopts an automated weighing system based on the fully integrated concept.
In BASF Polyurethane Special Products Co., Ltd., the automatic weighing system based on the fully integrated concept has also been well applied.
Application prospect
With the improvement of automation level and automation degree, automatic weighing technology based on the fully integrated concept will be more and more favored and trusted by users. The continuous innovation of weighing technology based on the fully integrated concept, for example, by adding fuzzy PID control to optimize the system, achieve more accurate system accuracy and response speed, further optimize the process flow and improve product quality. And this kind of flexible, concise, reliable automatic weighing solution is more likely to meet the higher and higher production requirements and the user's preference compared to the traditional secondary-table-based weighing system.
