The goal is to foster the integration of At the base, the internet of things requires remote IT Technologies with products, systems, solutions device access as well.

The communication media is either a cable modem or wireless modem. In more modern devices – in ex- ample a vending machine – the communication was using the cell-network and a SIM card was placed in each machine. It then communicated directly via a point-to-point connection with the dedicated com- puter to send sensor data – for example the fill-level – and other alarm messages to the machine owner. The business models resulting from this are mainly around logistics and maintenance as well as special condition monitoring and preventive maintenance. For example in the industrial environment, airplane turbines are sent to the airports and constantly mon- itored to send replacement parts in time to reduce the maintenance times. 5 COMMUNICATION OPC-UA INTEROPERABILITY The requirement for the communication of things The vision of IoT can only be realized, if the commu- and services inside the IoT is vastly different than to- nication of the central components is based on a day’s established structures: The IoT communication global communication standard that can fulfill the with devices will rarely happen directly.

The aggregation of information on many layers adds additional meta-data and therefore it is of critical im- portance to use a single standard. Scalability and the possibility of integration across all layers is required as well as platform and vendor independence. OPC- UA offers a complete solution for all requirements on all vertical layers for remote device access.
