Building Automation

In other words, we are assuming that instabus EIB exists and that you want to use, for example, an S7 PLC for administrative control tasks or, for example, an HMI system for central operator control and monitoring. The main emphasis here is in offices or apartment blocks etc.

The simplest option for connecting these systems to instabus EIB is provided by the DP/EIB link since these systems generally access the peripheral devices via

PROFIBUS.

The main areas of application are as follows:

S(Primary) open-loop control, closed-loop control and monitoring of heating systems

SVentilation, air-conditioning, and

SEnergy management and optimization

Industrial Automation

In this case, we assume that PROFIBUS exists and that you would like to include the electrical components of an assembly line, plant or production building in the automation. The main emphasis here is the equipment of industrial buildings themselves.

Applications include, for example, the following:

Slighting control

Sshutter control,

Smeasurement of temperature, wind strength, or the position of the sun,

Sdoor control and

Sbuilding access controls.

The instabus EIB is specifically designed for such tasks and provides a wide selection of components and a large network span (maximum 1000 m per bus). Up to 11,520 instabus EIB devices are possible in one network (a maximum of 15 areas each with a maximum of 12 buses each with up to 64 nodes).
