5.2.2 Connection
For access to the detectors HART® features, connect an industry standard HART® communicator
as shown in the following figures depending on the type of analogue interface (source or sink).
Note that for the HART® communication to work properly, a minimum loop resistance is
required in the current loop. The actual value of the serial resistance in the diagrams below may
vary depending on the rest of the resistance in the loop.
