Answer / paresh koradia

Communicator does not provide the 4-20ma or any kind of
supply voltage.However, we can force the output (4-20ma) of
the transmitter by communicator. The transmitter requires
an external power supply and the communicator just
connected parallely is used to either read the diagnostic,
process or else data from the transmitter plus to write
certain data like tag no., tuning parameters, calibration
data, ranges, etc.

Answer / ako

no hart communicator can only read and convert the
pressure,temperature and voltage.only multiprocess
calibrator can provide 4to20ma source

Answer / jigar anadkat

During simulation mode, HART communicator can provide 4-20
mA. However it will not be merely considered as a part of
calibration but the loop testing.
