The unit is suitable, according to the model, to work with either single loop connection or double loop fiber-optic connection. The SIU-FO series has the task toconvert the standard Mod- Bus communication from RS485 type to Fiber-optic so to increase the distance between devices and to increase significantly the noise immunity.ModelPower supply Communication port OptionType SelectionModel, SIU-FO1: Serial single loop fibre optic conversionFO2: Serial double loop fibre optic conversion(*) as standard.(**) on request.Power supply1:12 to 18VAC (48 to 62Hz) or10 to 24VDC (*)Communication portXX: none (*)S1: RS232 port (**) S2: RS485 port (*)XXXX:none (*)CommunicationRS485 portType Multidrop, bidirectional (static and dynamic variables)Connections2-wire + GNDMax. distance 1000m, termination directly on the moduleLEDGreen: running communication (one LED per loop)Yellow: reset statusAddresses247, automatically managed by the unitProtocolData (bidirectional)MODBUS/JBUS (RTU) Dynamic (reading only)All dataStatic (reading and All data writing only)Data formatSelectable by means of dip-switches:- 1 start bit,- 8 data bit,- none, even, odd parity- 1 or 2 stop bitsDelay Selectable by means of dip-switches: 1 or 2ms.Baud-rate Selectable by means of dip-switches: 300, 600,1.2k, 2.4k, 4.8k, 9.6k,19.2k, 38.4k, 57.6k,115.2k bit/sDriver input capability1/5 unit load.
