Establish 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.
In multidrop communication, each transmitter in the loop must have a unique HART
address.
