4.0 paradigm is enhanced process control. Traditionally, process control
solutions based on Cyber-Physical Systems (CPS) consider a top-down view
where processes are represented as executable high-level descriptions.
However, most times industrial processes follow a bottom-up model where
processes are executed by low-level devices which are hard-programmed with
the process to be executed. Thus, high-level components only may supervise
the process execution as devices cannot modify dynamically their behavior.
Therefore, in this paper we propose a vertical CPS-based solution (including
a reference and a functional architecture) adequate to perform enhanced
process control in Industry 4.0 scenarios with a bottom-up view. The proposed
solution employs an event-driven service-based architecture where control is
performed by means of finite state machines. Furthermore, an experimental
validation is provided proving that in more than 97% of cases the proposed
solution allows a stable and effective control. Keywords: Cyber-Physical Systems, Industry 4.0,
