11.5.10 HART Slaves
HART slaves are connected to Analog Input 1. Connection to HART
devices requires a Field Communication Card (FCC) equipped with
optional HART modem.
Figure 11-13. Connection of HART slaves.
A maximum of 3 HART slaves can be connected to the REX gauge in
multi-drop configuration.
If only one HART slave is connected, and the short address = 0, current
mode is supported.
With three HART slaves connected short address 1-3 must be used, and
the slave current is parked at 4 mA.
