HART
Communication signal:
HART communication signal (superimposed
on 4 to 20 mA DC signals)
Note: HART is a registered trademark of the FieldComm
Group. Use the setting tool that has the same
protocolrevisionasAXR.Itisnotpossibleto
communicatewithHART7AXRinusingHART5or
HART 6 setting tool.
Conditions of Communication Line:
Supply Voltage: 20.6 to 42 V DC
 LoadResistance:250to600Ω
(including cable resistance)
Read Figure 4.6.3.
HART Protocol Revision
HART protocol revision can be selected from 5 or
7 when ordering. (“-J” only)
The protocol revision can be changed by user
conguration.
The HART protocol revision at the time of
shipment is shown by the last number at the
serial number column of the name plate.
Note: ProtocolrevisionsupportedbyHARTcongura-
tion tool must be the same or higher than that of
AXR.
