: A field level is a level within the automation pyramid that classifies control system technologies and systems. The field level is between the production level and the control system
Accordingly, the field level denotes a level of production in the manufacturing and process industry. Input and output modules, process signals and the fieldbus are located at the field level.
What are the tasks at the field level?
As an interface to the technical production process, the field level represents the level at which input and output signals are sent and received, with the help of which the individual components of the system communicate via the control system. This makes it possible for system operators not only to control individual actuators – for example to open a flap or a valve – but also to regulate them depending on the given process parameters, for example by reducing the speed of a pump as soon as a certain flow rate
is exceeded becomes.
