2 Solution
2.1 Overview
Application areas
Set 6 is suitable for many industrial applications in which cost-effective weight
measurements have to be performed with little engineering overhead. This set is
particularly suitable if additionally automated logging functions are required in the
framework of the measurements.
Set 6, for example, is particularly suitable for the following sectors and fields of
application:

Food industry

Packaging industry

Raw materials

Mechanical engineering
Advantages

The integration of the SIWAREX WP231 weighing module into the S7-1200
ensures that the technological functions of the weighing module are combined
with all advantages of the PLC world (expandability, flexibility, software, HMI,
drives, communication interfaces, etc.)

Cost-effective high-precision weighing by means of SIWAREX load cell

Fast and simple configuration via TIA Portal V14

Automated logging functions provides evidence for the customers

Easy integration into existing systems due to a connection via PROFINET
Topics not covered by this application
This application focuses on the filling process by means of weighing technology,
the recipe management and the data logging in the load memory of the controller.
The filling process is deliberately kept simple and is realized via the digital control
of two sliders. When controlling an analog valve, the program code has to be
adjusted accordingly.
This application does not include a description of:

Positioning of the filling container (delivery and forwarding)
Assumed knowledge
Basic knowledge of SIMATIC S7-1200 and the TIA Portal is assumed.
