3.2.2 Multidrop Mode
Field devices in multidrop mode refer to the connection of several eld devices on a single
communication line. Up to 15 eld devices can be connected when set in multidrop mode. To activate
multidrop communication, each eld device address must be changed to a unique number in the
range 1 to 15. This change deactivates the 4 to 20mA output and changes it to 4mA.
