ABB provides control system for 30,000 ton/yr melamine project in China

30 January 2007

ABB is supplying an AC800F control system for a 30,000 ton/year melamine expansion project in China for Sichuan Chemical Works (Group). The AC800F system, which will be provided by ABB China, includes one engineer workplace, three operator workplaces with DigiVis software, and three pairs of redundant AC800F controllers with a redundant ring optical Ethernet network.

The system will process 2,632 I/O signals, using 166 S800 modules. I/O modules are connected with AC800F controllers via redundant Profibus DP. Profibus DP will also be used to communicate with frequency inverters and scale instruments.

The redundant ring optical Ethernet network is designed to accommodate future requirements, as new nodes can be added as needed.

In addition to the control system, the facility will have a catenation shut-down control system, also supplied by ABB China. ABB China’s system integration partner will provide control system cabinets, system engineering design, commissioning, and technical training services.
