As described in the PROFIBUS RS485 specification, each bus segment can have a maximum of 32 active devices. In order to be able to connect a larger number of PROFIBUS DP devices, it is necessary to segment the bus. The segments are then interconnected with repeaters which amplify and refresh the data signals. Repeaters can also be used for galvanic isolation of bus segments or bus sections. Each
repeater allows the PROFIBUS system to be extended by an additional bus segment with the maximum admissible cable length and the maximum number of fieldbus devices. Repeaters increase the signal propagation times. This should be taken into account during planning.
