VEGASON 61 • Four-wire 4 ... 20 mA/HART
6 Set up with the display and adjustment module PLICSCOM
The activation of SIL has the following impact:
•
In the menu item " Failure mode" under " Current output", the
parameters " Hold value" and " 20.5 mA" are blocked
•
In the menu item " HART mode", the function " Multidrop" is
blocked
Note:
For such applications, it is absolutely necessary to take note of "
Safety Manual".
HART offers standard and multidrop mode.
The mode "standard" with the fixed address 0 means outputting the
measured value as a 4 ... 20 mA signal.
In Multidrop mode, up to 15 sensors can be operated on one two-wire
cable. An address between 1 and 15 must be assigned to each sen-
sor.

In this menu item you determine the HART mode and enter the ad-
dress for multidrop.

The 4 ... 20 mA signal of the sensor is switched off. The sensor uses a
8)
constant current of 4 mA. The measuring signal is transmitted exclusively as
a digital HART signal.
