Details
Expanded device type code.
Manufacturer identification code.
Manufacturer device type code.
Number of preambles.
Revision level of HART Universal Command set implemented.
Revision level of device-specific command set implemented.
Transmitter software revision level.
Transmitter hardware revision level.
Device identification number.
pH, ORP, pION or Ion Concentration process value with units.
PV (pH, ORP, pION or Ion Conc) and PV percentage of range.
Current output value (mA).
PV value (pH, ORP, pION or Ion Conc) and
PV unit (pH, mV, ppb, ppm, %, ug/l, mg/l).
Temperature value and unit (°C or °F).
Reference Impedance value and unit (Kohm).
Sensor input value and unit (mV).
When set to 0, Current Output is active and provides an analog
output proportional to the Primary Value.
HART operates in point-to-point mode. When set between 1 to
15, Current Output is fixed at 4 mA and HART operates in
multi-drop mode.
Returns the expanded device type code, revision levels and
identification number of the device that contains the HART
identification tag sent with this command.
