PROMOTIC application acts as a system of supervision of the concrete mixing process. The operator can use ready-made recipes to produce more than 200 types of concrete. In addition, the system allows continuous stock control of raw materials and indicates the status of individual devices.
 
Communication between PC and PLC is provided by the PmMelsec communication driver.
 
Recipes
 
Currently, the system contains about two hundred recipes. Based on the chosen recipe, the system automatically calculates the amounts of individual components (cement, water, aggregate) needed to produce a given amount of concrete. Operators can continuously modify existing recipes and add new ones.
 
Stock inventory evaluation
 
After each production cycle, the application updates inventory stock levels by subtracting from the current state the amount of raw materials used in the last cycle. The operator has the option of continuously stocking supplies of individual raw materials. Container levels are archived on the hard disk of the computer.
 
Visualization
 
- Graphic representation of the technological equipment
- Current state of the devices (mixer, belt conveyors, dispensers)
- Process parameters archive
- Presentations in the form of trend levels in silos
- Usage of the alarm module to check the accuracy of communication with Rinstrum weighing sensors (communication with PLC on RS-485)
