  Nowadays, we are rapidly moving beyond bespoke detailed solutions tailored
for very specific problems, and we already build upon reusable and more general
purpose infrastructures and tools, referring to them as IoT, Industrial
IoT/Industry 4.0[1-3], etc. These are what will be discussed in this paper.
When Industrial IoT (IIoT) is concerned about, the enormous innovation
potential of IoT technologies are not only in the production of physical
devices, but also in all activities performed by manufacturing industries, both
in the pre-production (ideation, design, prototyping) and in the
post-production (sales, training, maintenance, recycling) phases . It is also
known that IIoT acquire and analyze data from connected devices, Cyber-Physical
Systems (CPS), locations and people (e.g. operator); along with its
contemporary new terms, such as 5G, Edge computing, and other ICT technologies
with their applications[4] . More or less it is drawn upon on its combination
with relative monitoring devices and actuators from operational technology
(OT). IIoT helps regulate and monitor industrial systems [2], and it
integrates/re-organize production resources flexibly, enhanced OT capability in
the smart value chains enabling distributed decision-making of production.
