units can be addressed individually using a point-to-point
connection or the standard (multidrop) bus.
Point-to-point connection:
HART
®
master device connected to one
HART® field unit. With this connection, the device address must
also be set to '0'.
Standard (multidrop) bus:
Up to 15 field units connected in
parallel to a single pair of wires. The master device distinguishes
them by their preset addresses between 1 and 15.
