Abstract
A system is provided to conduct communication in a facility with equipment in hazardous and safe areas. The system includes at least one field device in a hazardous area of the facility; one or more controllers, located in a safe area of the facility, for managing the at least one field device; and a field barrier, between the safe and hazardous areas, to limit at least electrical energy, which is supplied to the at least one device, at or below an electrical energy threshold in the hazardous area. The system also includes a bus system to supply electrical energy across the field barrier to the at least one field device using electrical wiring and to enable communication between the at least one field device and the one or more controllers across the field barrier using one or more fiber optic cables.
