Carry out your settings via the appropriate keys and save with
[OK].
There are two reset modes:
•
Reset to default: with only a few exceptions, all settings will be
reset to default. Exceptions are: Host name, IP-addr., subnet
mask, time, language.
•
Reset on measurement loop: The settings of the selected meas-
urement loop will be set to default. The measurement loop is
deactivated and the TAG name reset to default.
With every 4 … 20 mA/HART sensor, the measured value can be
transmitted via analog current signal or digital HART signal. This is
regulated via the HART mode or the address. If a HART sensor is set
to address 0, the sensor is in the standard mode. Here the measured
value is transmitted digitally on the 4 … 20 mA cable.
In mode HART Multidrop, an address from 1 … 15 is assigned to the
sensor. By doing so, the current is fix limited to 4 mA and the meas-
ured value transmission is only made digitally.
Each sensor connected to VEGAMET 625 must operate in mode
HART multidrop and must be provided with different addresses in
the range between 01 … 15. Via the menu item "Sensor address", it
is possible to change the address of the connected sensor. For this
purpose, enter the previous address of the sensor (factory setting 0)
and in the next window the new address.
Note:
When addresses are being assigned, only one sensor with the same
address must be connected on the bus. If this is not the case, the sen-
sor cannot be accessed and it is not possible to assign an address.
First of all, enter the previous address of the sensor to be modified
(factory setting 0), then you can enter the selected HART address in
the range of 01 - 15 in the menu "New address". Make sure that no
address is assigned twice.
With instrument versions with integrated RS232/Ethernet interface,
a manual data transmission to a WEB-VV server can be trigger, for
example, for test purposes. Requirement is that a WEB-VV event was
configured in advance via PACTware/DTM.
