Any modern company aspiring to sell complex products to a wide market must be able to count on its production equipment. At the latest when safety-critical quality characteristics are demanded, experience in process control technology is an essential precondition for plant manufacturers along with know-how in the field of control engineering.

futronic's successful implementation of a fully automatic weighing system for tyre manufacturing provides further proof of our expertise in this sector. A Siemens MICROBOX 427B controller establishes a connection to actuators and sensors over the ET200S bus system and communicates with identification and data acquisition devices via Profibus and Ethernet. The Siemens Panel PC 627 makes modifying and monitoring the process both easy and convenient. Process visualisation is based on WINCC Flexible 2005.

The system integrates the following main features:

• Recipe controlled weighing system for chemicals
• Container identification with RFID reader
• Barcode management (creation and reading)
• Batch reporting and transfer to a control system
• Guaranteed plant availability even if the server fails
• Recipe transfer for four production lines
• Remote maintenance over VPN
