摘要

The present invention relates to a system for determining a real process parameter of at least one real field device, such as an actuating valve and / or pump, which is located in a real flow path of a process-technical plant, such as a chemical plant, a food processing plant, a power plant or the like , integrated and designed to influence, such as setting, driving, heating, cooling or the like, the real process fluid flow according to a field device-specific real influencing factor, comprising a virtual twin flow path in which the real flow path is virtually mapped and a twin Process fluid flow is influenced virtually according to a twin influencing factor corresponding to the real influencing factor of the at least one real field device, at least one twin field device corresponding to the at least one real field device, the twin flow path being a real output parameter of the real process fluid flow, such as temperature, speed, pressure, volume flow or the like, and / or the real field device, such as an actuating path, a pump power or the like, receives and based on the at least one twin influencing factor fluid flow upstream or downstream a twin process parameter of the at least virtually determines a twin field device corresponding to a real field device, the virtually determined twin process parameter being fed to the at least one real field device as the real process parameter to be determined for further influencing the real process fluid flow.
