Used controller: VIPA-500.
Used visualization program: PlantVue .
1.Goal of the Project
Task of the project - perform automation operations at an ecologically clean fuel (charcoal) plant, company "Livanu Karbons".
2. Stages of the Project
The execution of the project can be divided into following stages:
- Formation of the technological diagram of the devices (based on the documentation company "Lambiotte" documentation);
- Development of list of devices to be managed;
- Preparation of work plan;
- Structural diagram of the automation;
- Electrical design (Diagrams of control panel and assembly);
- Ordering and procuring component parts (management system, sensors, etc.);
- Algorithm of the management system work;
- PLC programming (programmable controller VIPA-500);
- SCADA programming (visualization on PlantVue base);
- Assembly of control board;
- Testing of the management system before delivery to the Contracting authority;
- Delivery of the control board to the object;
- External installation of electrical devices at the object;
- Testing of the management system at the object;
- Staff training and submission of project documentation to the Contracting authority;
- Putting into operation.
3. Production technology
Production consists of the following parts:
- Equipment for wood loading retort, including winches
- Equipment for hot air supply
- Equipment for cold air supply
- Equipment for coal cooling
- Equipment for coal unloading

4. Management system
Production main management system consists of:
A) 1st retort control systems;
B) 2nd retort control systems.
Management system consists of:
- Computer with installed software package - "Plant Vue" (SCADA)
- Processor "VIPA-500"(PLC)
- Weighing module for raw materials basket - "Fatek"
- Peripheral Station - "Crevis"

Internet through Router device is used to ensure remote observation and adjustment of software and operating modes.
Production process starting with preparation of raw materials and ending with unloading of finished products at the warehouse can be controlled by one operator.
5. Electrical devices
Electrical design is prepared using P-plan software package.

8. Project feature
Specialists from Belgian company "Lambiotte" participated in the process of preparation and execution of the project. This cooperation ensured that an efficient and technologically oriented production management system was developed.
Use of different controllers for each retort increased safety and security of the management system.
