Parameter
Meaning
Example
Default
Start-up time
Time in seconds during which the field device
requires the "start-up voltage".
5 s
5 s
Start-up current
Current in milliamperes required by the field de‐
vice for the "start-up time".
14 mA
14 mA
Operating voltage
Voltage in volts that the field device requires in
normal operation after the "start-up time".
12 V
16 V
Lead time
Time in seconds after the "start-up time" that the
field device requires to provide valid measured
values.
10 s
10 s
Power-on time after ex‐
ternal trigger
Time in seconds during which the field device is
supplied with current following communication
via wireless.
● Requirement: The configuration mode "au‐
to" must be selected.
90 s
10 s
Configuration time
Time in seconds during which the field device is
supplied with current for configuration (with SI‐
MATIC PDM or local on-site control of the de‐
vice).
● Requirement: The configuration mode "Con‐
figuration" must be selected.
300 s
300 s
Last battery change
Shows the date on which the "Battery change"
button was last pressed.
● If the WirelessHART adapter is not connec‐
ted to the network during the initial commis‐
sioning, the date is set to 01.01.1970.
● The first time is is connected to the network
manager, the date is updated.
Temperature min.
Lowest temperature in degrees Celsius that the
WirelessHART adapter was subjected to since
the last time the temperature was reset.
-10 °C
Temperature max.
Highest temperature in degrees Celsius that the
WirelessHART adapter was subjected to since
the last time the temperature was reset.
50 °C
Reset temp max/min
By pressing this button, the minimum and max‐
imum values of the temperature are reset.
Normalized consumed
energy
Current taken from the battery unit since the last
battery change.
● This value is not the actual consumption of
the WirelessHART adapter but the chemical
energy consumption of the battery unit.
