CMS control systems from Simma Electronic can be flexibly dimensioned and therefore also adapted for a wide range of areas of application throughout the construction materials industry.

The aggregate filling and cement filling can be integrated into the controls and operated via the on-screen visualisation

Complex tasks need simple solutions.

The operation of the controls is simple and easy to understand. Maximum investment protection is ensured through the use of the industrial versions of standard PC and PLC components. The controls are programmed using Microsoft.Net and Siemens Step 7. Thanks to the use of global standards such as Profibus and Profinet, all electronic assemblies can be connected.

Investment protection through the use of standardised components.

Our CMS control systems were developed from practical experience. This means that all modules and functions are already in use by our customers and are doing good work there. You can access a wide range of functionalities. Wherever necessary we will implement special customisations for you.

Workability curve for each batch for a vehicle is plotted. This allows early identification of the final workability. The mixer only opens once the workability is within the desired range. All data recorded during production can be shown in detail per batch.

Everything at a glance – be informed if something isn’t right.

The workability curve can be displayed if the power panel is equipped with a power monitoring device. In addition, workability control is also possible. A batch protocol is saved for each batch produced. Each batch protocol contains all the data arising during the production (manually dosed materials are also recorded). The batch protocols are saved in the database and can therefore be viewed and even printed at any time.
