Human-machine interface products, often referred to as "touch screens", include HMI hardware and corresponding dedicated screen configuration software. Generally, different manufacturers' HMI hardware use different screen configuration software, and the main type of connected equipment is PLC. Configuration software is a general tool software product running on PC hardware platform and Windows operating system, and can also form HMI products together with PC or industrial computer; general configuration software supports a wide range of equipment types, such as various PLCs, PC boards, instruments, inverters, modules and other equipment, and because the PC hardware platform has powerful performance (mainly reflected in speed and storage capacity), the general configuration software is also much more powerful and suitable for large-scale monitoring systems.
