mounted CPUs. This term is used to describe a single, non-redundant process station. In the investment of modern automation system, due to the hardware equipment department It only takes up less cost in the whole system, then write engineering applications The cost of software becomes increasingly important. Generally speaking, a self The engineering application software…

Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments. Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can…

The scale of the system is highly scalable, and a single-system supports 1 to a maximum of 100 control stations and 100 operating stations. each control The station can support several thousand I/0 points at most, and the scale of the whole system can be expanded. The hardware of the…
