The device’s polling address can be configured in the
HART
menu. As delivered, the value is set to
zero (shown as “0”). Multi-drop mode is activated with values between “01” and “63”. In multi-drop
mode, the output current is a constant 4 mA.
After activating the HART interface, the four
dynamic variables
PV, SV, TV, and QV are displayed.
Dynamic variable
PV (
Primary Value
) represents the process variable assigned to current output I1.
The three other
dynamic variables
SV, TV, and QV (
Secondary, Tertiary, Quarternary Values
) can be freely
assigned.
The HART information required for system integration, e.g.,
Device Revision
,
Device Type ID
, is displayed
in the
Diagnostics
HART Information
menu. Further information can be downloaded from the
relevant product page on our website, e.g.:
• Device description (DD)
• HART command specification
