The RS485/PROFIBUS Optical fibre Ring coupler reroutes the PROFIBUS from copper conductors to optical fibres. The coupler is a passive bus participant. The transmitter and receiver for the optical fibre ring coupler are activated in an intrinsically safe way, thereby ensuring that the transmission power of the transmitter does not exceed the permitted limits. The electronics for the signal conversion are accomodated in the flameproof MODEX enclosure – Transmitter and receiver for the Optical fibre-coupler are intrinsically safe headed. The intrinsically safe control transmitter and receiver of the electronic system guarantee that the transmitter rate does not go beyond maximum value limits.
Depending on the topology, several devices can be arranged in a ring. The ring must contain a master device. All other devices should be configured as slaves. The master must be connected to the level above it (e.g. control system).
