4.3.1.

 

BUS (HART

®

) communication 

 

The output of the device can be used in two ways: 

1. Current loop output and HART

®

  

2. Passive, HART

®

 protocol 

The HyView program supports the use of both modes. 
According to the Rosemount Standard, HART

®

 communication can be used as a point-to-point connection between VF05 

as a “slave” and a HART

®

 

“master”.

 

There are two modes of communication: 

•

 

If the device (HART

®

 

short address 0) is set to current loop transmission (4…20 mA), 

only one device can be in the HART

®

 communication loop 

•

 

For multidrop operation (4mA), several devices (max. 15) can be connected to one HART

®

 communication loop. In this case, a short address other than 0 

must be set for the device.

The VF05 two-wire device is supplied by HYCONTROL with the technical specifications requested by the customer, so it is ready for operation immediately after 
installation and wiring up. 
Measuring starts less than 20 seconds after switching on. 

Attention! The initial current consumption of the device is 3.5 mA right after switching on!

 If there is 

a change in the installation data due to shortening a cable probe, the set parameters must be changed according to the application before starting the measurement.
