the work focuses on the development of a software solution for observation and management of an industrial unit for automation. The actual software solution is designed for tablets and mobile phones running the Android operating system. All presented paradigms can also be applied to other mobile platforms and operating systems. Custom software allows the operator to control and manage devices remotely, but the major focus is on observation, because an operator's actions are expected only in critical situations. SW solutions in the case study are solved as intuitively as possible. So parameter adjustments may be performed by laymen with a simple user interface - which places fewer demands on the operator of the automatization units. The paper is focused on the definition of the issue, it also introduces the reader to the 1P-LOG device (and its variants); but mainly reflects extensively on the creation of the low-level network protocol bridge to the application. The issues of one way link and connections, and issues in broader network connectivity (internet, tunnelling, addressing) are resolved.
