The presented work is part of IGF project 17715 BG ”M2M@Work” which is funded by the

German Association for Research ’Forschungsvereinigung beim ZVEI e.V. – FE, Lyoner Str. 9,

60528 Frankfurt/Main’ in the AiF under the program for the support of industrial research and

development (IGF) by the Federal Ministry of Economics and Technology based on a decision

of the German Bundestag.

A user of an industrial communication system expects a certain

process value at a certain interface within a defined time frame

without any errors under defined conditions.

Currently there is no general M2M standard available for industrial

automation which fits to all communication tasks.

A unified interface between communication and application is not

available.

The model must be independent of a certain M2M technology and the

model must be open for future developments in M2M communications.

The model should represent the conditions of reality as accurate and

complete as possible and necessary.
