What is weighing and dosing automation?
Weighing and dosing automation focuses on the accurate weighing and dosing of raw materials in industrial processes. This can include solids such as powders and granules or liquids such as oils and chemicals. The goal is to add the right amount in the right batch or recipe. Automation with PLCs and Siwarex modules makes the process more reliable, faster and more consistent than manual dosing. This is especially important in industries where quality and safety depend directly on correct dosing.
Important standards and guidelines
NEN-EN 60204-1 - electrical safety of machinery.
When integrating weighing systems into machines, the following applies NEN-EN 60204-1 applies as the standard. Among other things, this guideline describes electrical safety, cable coding and protection devices. It ensures that automation is applied not only accurately, but also safely.
IEC 61131-3 and ISA-88 - software and batch control
The international standard IEC 61131-3 defines how PLC programming is constructed, while ISA-88 provides guidelines for batch control and recipe control. Together, they provide a solid foundation for standardizing and making weighing and dosing processes traceable. These standards help companies meet quality and traceability requirements without requiring additional manual steps.

Applications in industry
Weighing and dosing automation is widely used in industries where precision and efficiency are crucial:
- Food & beverage: recipe-driven weighing of ingredients for consistency and food safety.
- Chemistry: dosing of chemicals in production processes with high safety risks.
- Bulk handling: handling of powders and granules in silos, packaging lines or conveyors.
- Pharmacy: accurate weighing of raw materials for drug production (within European guidelines).
In all of these applications, traceability plays an increasingly important role. Being able to retrieve batch data is essential for audits and quality control.
Advantages of weighing and dosing automation
The integration of Siemens Siwarex modules into TIA Portal offers several advantages:
- Accuracy: minimizes errors and ensures consistent quality.
- Efficiency: Faster production and less waste due to consistent dosing.
- Traceability: batch data can be easily stored and linked to ERP or MES systems.
- Flexibility: easy prescription changes without major software modifications.
- Reliability: direct integration with Siemens PLCs and HMIs for a robust solution.
The process from design to commissioning
The realization of a weighing and dosing automation system involves several stages:
- Design – engineers work with EPLAN Pro Panel and TIA Portal to create an engineering design that complies with applicable standards.
- Panel building & integration – Switchboards are built in accordance with NEN-EN 61439 and equipped with Siwarex modules and PLCs.
- Software development – recipe-driven processes and batch control are configured in TIA Portal.
- Test phase (FAT) – weighing systems are extensively tested in the workshop to ensure accuracy and reliability.
- Commissioning (SAT) – On-site validation, including batch registration and interfacing with SCADA or MES.
- Delivery & documentation – Including CE Declaration of Conformity and manuals to ensure hassle-free audits.
This structured process creates a solution that is secure, reliable and future-proof.

Frequently asked questions about weighing and dosing automation
How do you guarantee accuracy in weighing systems?
Accuracy is achieved by using calibrated load cells in combination with Siemens Siwarex modules that integrate directly into TIA Portal. In addition, software-based corrections, error detection and periodic validation during FAT and SAT ensure that deviations remain minimal.
What is the advantage of Siemens Siwarex in TIA Portal?
The integration of Siwarex modules into TIA Portal provides one central environment for both PLC programming, HMI configuration and weighing functionality. This reduces complexity, simplifies maintenance and provides direct interfacing with recipe-driven processes and batch recording.
How does batch dosing work in a PLC controller?
Batch dosing means that a PLC controls dosing based on preset recipes. The Siwarex module measures the weight and controls the valves or conveyors until the set amount is reached. The PLC records all batch data, so traceability and audit trails are available.
What industries use weighing and dosing automation?
Weighing and dosing automation is widely used in sectors such as food & beverage, bulk handling, chemicals and pharmaceuticals. In each of these sectors, accuracy, traceability and efficiency are of great importance, for example for meeting quality standards and regulations.
How are weighing systems tested and validated (FAT/SAT)?
During the Factory Acceptance Test (FAT), the systems are tested in the workshop for accuracy, error detection and communication with the PLC. In the Site Acceptance Test (SAT), this is done on site in the field environment. This ensures that the system functions reliably under real-world conditions.
