  Industry 4.0 offers many possibilities for creating highly efficient and
flexible manufacturing. To create such advantages, highly automated and thus
digitized processes and systems are required. Here, most technologies known
from the office floor are basically suitable for these tasks, but cannot meet
the high demands of industrial use cases. Therefore, they cannot replace
industrial technologies and devices that have performed well over decades "out
of the box". For this reason, many technologies known from the office floor are
being investigated and adapted for industrial environments. An important task
is the virtualization of process controls, as more and more devices use
computation offloading, e.g. due to limited resources. In this paper we extend
the work on our novel architecture that enables numerous use cases and meets
industrial requirements by virtualizing process controllers. In addition, a
testbed based on a factory scenario is proposed to evaluate the most important
features of the presented architecture.
