6.4.8 

Menue "Communication" 

In the "Communication" menue the settings for the HART communication are summarised.  

  

Menue entry 

Description 

HART address 

Setting the HART address for device identification in multi-drop 
mode 

Current mode 

Setting the current mode (proportional/constant) 

HART data 

Display of HART information (HART-Tag, HART-Descriptor etc.) 

Send-preambles 

Setting of the number of send-preambles for 
HART communication 

Table 16: "Communication" menue 

  

6.4.8.1 

HART address 

This  address  corresponds  with  the  short  address  which  is  used  for  the  HART-
Communication. It can be set within a range of 0 to 63. Please note, that setting the short 
address between 1 and 63 will not automatically activate the constant current mode. This 
must be done under the menue “Current mode” (see 6.4.8.2). 

  

6.4.8.2 

Current mode 

The  current  mode  determines  whether  the  output  current  of  the  device  is  set  to  respond 
proportionally to the measured value (selection “proportional”) or whether it should remain 
constant  at  4 mA  (selection  “constant”). When  the  current  mode  “constant”  is  in  use,  the 
measurement  value  can  only  be  read  using  HART-commands  (e.g.  for  HART-multidrop-
operation). 

  

6.4.9 

Menue "System" 

In the "System" menue, device-relevant functions are summarised.  

  

Menue entry 

Description 

Device ID 

Setting the device ID (e.g. to display a free-text in the display) 

Device data 

Display of device data, such as from measured value display (see 
6.2.1) 

Factory reset 

Reset to factory settings 

Device reset 

Restarting the device (such as after a power outage)
