Abstract
The invention relates to a compiler and a method for compiling control logic for a plurality of devices of a networked control system, particularly to the automated assignment of control logic to devices. The invention provides with a compilation an automatic assignment procedure of an executable runtime code to devices of a networked control system. The assignment process of control logic to the devices may take various optimization criteria into account which include various distribution aspects, e.g. network resources or capabilities, such as available bandwidth or reliability of the network links, and device resources or capabilities, e.g. CPU, memory, power source or sleeping behavior which may influence the observed behavior of the devices, e.g. due to transmission delay or data packet loss.
