Comparison with 35AE93: 35AE93 has been strengthened in some specific functions, such as outstanding performance in high-speed data acquisition, which is suitable for scenarios requiring very high data acquisition speed, such as high-speed inspection in semiconductor manufacturing; while 35AE92 is more balanced in terms of comprehensive performance, with outstanding performance in control accuracy, communication flexibility, and scalability, which is widely applicable to a variety of industrial automation scenarios. automation scenarios.

Communication interface introduction:

RS-232 interface: it is a standard serial communication interface, which can be used for close-range point-to-point communication with computers, printers, modems and other devices. It adopts asynchronous communication method, and the transmission rate is usually in the lower range, such as 9600bps, 19200bps, etc.. In industrial automation, it is often used to connect programming devices for parameter setting, programme downloading and debugging of controllers, and can also be used for data interaction with some simple intelligent meters.

RS-485 interface: It is also a kind of serial communication interface. Compared with RS-232, it has stronger anti-interference ability and longer transmission distance, and can realise half-duplex communication of multiple devices on the bus. It supports communication protocols such as Modbus - RTU, which can easily connect multiple ABB 35AE92 controllers or other devices supporting Modbus - RTU protocol into a network to achieve distributed industrial control and data acquisition.

Ethernet interface: Ethernet interface, supporting TCP/IP protocol, with high-speed data transmission capability, can achieve real-time data interaction and remote monitoring between the controller and the host computer, other intelligent devices. Through the Ethernet interface, ABB 35AE92 can be connected to the factory's LAN or the Internet, which is convenient for engineers to monitor and manage the industrial site in the office or remote locations, and can also be integrated with the enterprise's MES, ERP and other systems to achieve a higher level of production management and optimisation. It also supports a variety of industrial Ethernet communication protocols such as EtherNet/IP, Modbus TCP, PROFINET and so on. Among them, EtherNet/IP is suitable for interconnection of devices in industrial automation field; Modbus TCP is the implementation of Modbus protocol on top of Ethernet, which is widely used for communication between devices of different manufacturers; PROFINET is an Ethernet-based fieldbus standard, which is mainly used for distributed device control in industrial automation system.
