Bus address
[0] to 15 · ESC
Using the HART
®
protocol, all connected control room devices
and field devices can be addressed individually using a
point-to-point connection or the standard (multidrop) bus.
Point-to-point: HART
®
master drive connected on HART
®
field
device. With this connection, the positioner address must
always be set to '0'.
Standard (multidrop) bus: A maximum of 15 field devices can be
connected in parallel to a single pair of wires. The
HART
®
master drive tells them apart by their addresses
in the range from 1 to 15.

HART
®
write protection
[No] · YES · ESC
When the write protection function is activated, device data can
only be read, but not overwritten over HART
®
communication.
