> With a total investment of 550 million yuan, the project of 120,000 tons of dry aluminum fluoride supporting ice crystal production line will be built in two phases, of which the first phase will build an annual production line of 60,000 tons of dry aluminum fluoride. It is an important project of Guangxi Aluminum's "second entrepreneurship", a key project of the autonomous region's coordinated promotion of the "double hundred and double new" projects, and a key project of the autonomous region's major project on-site observation and promotion meeting. Aluminum fluoride products have high purity and stable quality, meeting or exceeding the national aluminum fluoride AF-O quality standard.

Configuration Scheme

● I/O points: 1788 points
● SIMATIC PCS7 V8.0
● DCS control cabinet: 4 sets
● Client/Server (C/S) architecture
● CPU 410-5H (redundant) + ET200SP
● AI and AO are all equipped with safety barriers
● Collect third-party data through modbus communication

Project Highlights

● CPU redundant configuration to improve system reliability
● DCS and SIS integration project, using SIS system to protect important devices.
● SIS modules are proven automation technologies and products used to control processes and ensure that they are immediately in a safe state after an interruption.

User benefits and project significance
● Full DCS and full centralized control project, through PCS7, realized accurate and stable control of aluminum fluoride. According to the on-site control process, the special function attribute block was customized and developed, which improved the automation control level of the whole factory.
● The first use of the PCS7 system enabled the transition from the original PLC control to DCS control, which had a positive impact on the continued use of the PCS7 system for subsequent projects.
