PROFIBUS PAFISCO model
FISCO = Fieldbus Intrinsically Safe ConceptFeatures:
devices are current sinksonly one segment coupler powersdevice capacity and inductivity are limitedlimited line length to 1000 mlimited spur length to 30 m/device, not cascaded
Advantages:no calculation of intrinsic safetysimple connection simple to be extendedno EEx system certification necessary!
