Advantys FTB splitter boxes are of the monobloc type.
Each splitter box comprises one part for connection of sensors and actuators by
means of M12 connectors, and one part for connection of splitter boxes on
Profibus-DP fieldbus.
This splitter box enables inputs/outputs to be located remotely, as close as possible
to the equipment being controlled.
Profibus-DP presentation
The Profibus-DP (Process Fieldbus Decentralized Peripheral) is an open type
fieldbus system for industrial applications. The Profibus standard is described in
standard EN 50170.
The physical link is a simple, type A, shielded twisted pair.
Data exchange between the Master (processing unit) and the Slaves (decentralized
devices) is performed in a cyclic manner.
A maximum of 32 Slaves can be connected to a bus segment. To increase the
number of Slaves, repeaters must be installed in order to create new bus segments.
The repeaters also provide galvanic isolation of the bus segments.
The total number of slaves must not exceed 126.
The bus must be fitted with a line terminator at each end of each segment created.
