A major American brewing company was in need of a solution for its production facilities that could network multiple production processes together and be able to withstand temperatures in excess of 140°F without failing. Multiple controllers and production machines needed to be seamlessly connected, and it had to work flawlessly. After extensive research and testing, the company chose to deploy Comtrol’s DeviceMaster® UP.
Loaded with Modbus/TCP firmware, the DeviceMaster UP provides the brewery a flexible, easy-to-use and highly robust solution. Controllers include SCADA systems communicating over Modbus/TCP and PLCs communicating via Modbus/TCP, serial Modbus/RTU or serial Modbus/ACSII. The production machines communicate via ASCII data, Modbus/RTU or Modbus/ASCII. Further complicating the situation, the ASCII data machines need to communicate to each controller independently.
The DeviceMaster UP seamlessly networks the controllers to the production machines. The automatic Modbus protocol conversion functionality enables multiple Modbus controllers to communicate to the serial Modbus machines. The industry’s first command/response mode enables multiple controllers to independently communicate to the ASCII production machines.
