Dynamic Variables
Dynamic Variable Description
Dynamic Variable
PCT
Percent Of Output Range (PV scaled to 0-100%)
AO
Analog Output/ Loop Current
PV
Primary or Process Variable
SV
Secondary Variable
TV
Tertiary Variable
QV
Quaternary Variable
To select the measurement which appears on the Analog Output, the relevant Device Variable
must be assigned to the PV (Primary or Process Variable) By default, Sensor 1 (SEN1) is
assigned to the PV.
Note:
To use a calculated Device Variable, both sensors’ engineering units (EGU) must be
compatible (i.e. the same or both temperature units). If a calculated Device Variable has
different engineering units (EGU) from the Sensors’ EGU, scaling will need to be used to
change the units.
HART Broadcast Messaging (Burst Mode)
The
THZ
3
/TDZ
3
supports enhanced broadcast messaging more commonly referred to as burst
mode. When set to burst mode, the
THZ
3
/TDZ
3
will proactively send out messages instead
of waiting for the host to request them. This enables event driven communication (high, low,
deviation of signal or change in status) and/or timed communication (every x seconds) to the
host. Up to 3 different burst messages may be configured in the
THZ
3
/TDZ
3
. Please see section 4
for more information on burst mode configuration
Note:
When using burst mode in the THZ
3
/TDZ
3
, the host must also be configured to
communicate in burst mode.
