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.
