has been developing its own Software Department since more than 15 years. More than 1500 concrete batching plants operating worldwide provide an enormous feedback for the improvement. Recently this large experience has been transformed into a simple, comprehensive and extremely sensitive electromechanical structure - a MECAS Automation System.
Only High Quality Components

The control panel in based on SIEMENS equipment which is available in all the parts of the world to provide the best quality and worldwide support. No manufacturer-specific hardware ensures maximum flexibility for the final costumer. Main logical controller is a modular SIEMENS S7-300 PLC which is proven to be robust and reliable with wide capabilities for modification and improvement. Ethernet connection provides exceptional responsiveness touch panel allows operation without the main PC.

Real Time Visualization

Main batch window resembles the actual characteristics of the concrete plant. Comprehensive visualization is showing the actual state of the related discharge gate,scale,pump,valve or any other hardware. Moreover, the main window is customizable an can be easily adjusted to changes in the concrate batch plant configuration.

Automation System
3 Main Operating Modes

The system allows Fully Automatic, Semi-Automatic and Manual operating modes. Switching between modes is possible from the main batch window with a single click. The system starts in fully automatic mode by default, minor corrections and interventions can be done with the help of the buttons on scales,pumps,gates and the mixer. The system switches to semi-automatic mode automatically when operator is interfering by pressing the related buttons. In case of a need or emergency operator can completely turn of the automatic production and switch to manual mode.
