The team of Professor Yan Yi and Professor Wu Huifeng from the School of Computer Science and Technology of Hangzhou Dianzi University is an effective force in independently developing the IEC 61131-3 programming system platform. Their IDE development environment CASS is equipped with logic control, sequence control, process control, mechanical safety control, multi-axis coordinated motion control, visual inspection and control, fieldbus and industrial Ethernet communication and other comprehensive functions, and also creatively introduces the concept and implementation of equipment database into PLC system. The operation data of intelligent equipment can be entered into a time sequence database in a specified data format in real time, which is used by algorithms such as artificial intelligence and vision. Its programming capabilities were certified by PLCopen International in 2017. CASS platform has broad adaptability, function configuration and cutting freely, not only for complex intelligent equipment to provide application software integrated development, debugging and operation maintenance, but also for various types of MCU at home and abroad to provide embedded PLC system software development environment. The systems they provide have been widely used in industrial robots, CNC winding machines, CNC spring machines, all-electric injection molding machines, wood processing production lines, customized embedded PLC, etc.
