Establishing multidrop communication

Multidropping transmitters refers to the connection of several transmitters to a single
communications transmission line. Communication between the host and the
transmitters takes place digitally with the analog output of the transmitters deactivated.
Multidrop installation requires consideration of the update rate necessary from each
transmitter, the combination of transmitter models, and the length of the transmission
line. Communication with transmitters can be accomplished with HART
host implementing HART protocol. Each transmitter is identified by a unique address and
responds to the commands defined in the HART protocol. Field Communicators and AMS
Device Manager can test, configure, and format a multidropped transmitter the same way
as a transmitter in a standard point-to-point installation.
