In each segment only one active
device , normally the associated
apparatus is allowed to provide the
necessary energy for the fieldbus
system. All other equipment
connected to the bus are not allowed
to provide energy to the system.
Separately powered equipment needs
a galvanic insulation to assure that
the intrinsic safe fieldbus circuit
remanis passive.
