Remote Operation Instructions IFC090 HART
1 General
Information
The IFC090 is a two-wire transmitter with 4...20mA current output and HART
capability. Dependent on device
implementation it is available with active current output (‘Standard + HART’, ‘Modis-3’) or passive current output
(‘Standard + HART’, ‘Modis-1’, ‘Modis-2’).
General Characteristics of the IFC090 HART
interface:
•
Multidrop Mode is supported
•
Burst Mode is not supported
Electrical connection: Refer to sections 2.1, 2.2, 2.6 of the “Installation and Operating Instructions Electromagnetic
flowmeters IFC 090 K/F” (KROHNE) – for ‘Standard + HART’ device implementation, and to sections 4-6 of the
“Information about IFC 090i (Modis-devices)” (KROHNE) – for ‘Modis’ instrument implementations.
There are two ways of using the HART
communication:
a) As a point-to-point connection between the IFC090 and the HART
master equipment. The instrument may be
equipped with either active or passive current output (‘Modis’) or be configured with desired current output (‘Standard
+ HART’).
b) As a multipoint connection (multidrop) with up to 15 devices (IFC090 or other HART
equipment) in parallel. The
instruments must be equipped (or configured) with passive current output.
