For the connection shown in Figure 56, use the option ONLY HART
mode, the internal resistor and the mA input are disabled. The HART
250 ) must be externally inserted in series with the power source and the transmitter. In
this case, the calibrator does not perform the measurement of the transmitter current, but
can read and configure its parameters via HART

2.2.2. Starting Communication

Entering the
CONFIGURATOR option (FH version only) or calibrator to allow access to Full-Hart
software (DD library) with all device parameters. By disabling this function, the CH
software is started with the basic and universal commands for Hart® communication
(zero, span, trim mA etc.).
Then set the internal resistor (250 ) and set the HART® connection type (mA +
HART® or ONLY HART®).
For the CH option must be inserted the instrument ADDRESS with which to
communicate and press the CONNECT button. If the address of the instrument is not
known, the SEARCH button can be pressed, which will search for instruments in the
address range from 0 to 15.
Up to 15 instruments in a HART® network (addresses 1 to 15) are allowed. For a
single field instrument with address 0, on the mA IN + HART® connection, the primary
variable can be read both analog (4 to 20 mA) and digital (HART®). In network
connection, the only way to read the primary variable is digitally (ONLY HART®).
