:6,F,8,A0i8|6|9,
The LF60*F series electromagnetic flowmeter uses the
HART** protocol
to transmit digital signals
over the 4-20mA output line. The AF900 hand-held terminal is used to communicate with the LF60*F
using the HART protocol.
You can check or change configuration parameters, calibrate the
flowmeter or monitor the flowmeter measuring value from a remote place.
For the detailed operation and specification of HHT, refer to the "Hand-held Terminal for Sensor with
Communication Function AF900 Instruction Manual" (6F8A2195).
*1 HART protocol:
The ’’HART protocol”, which stands for Highway Addressable Remote Transducer, is the
name of the communication protocol for industry sensors that is recommended by HCF
(HART Communication Foundation).
By adding an optional PROFIBUS communication board to the converter for electromagnetic
flowmeter converter: LF60*F, the converter can be used as the PROFIBUS-PA slave device for digital
data communication with the PROFIBUS master device.
For details of PROFIBUS communication, refer to the "PROFIBUS Communication Instruction
Manual".
To perform HART communication by connecting the converter for electromagnetic flowmeter:
LF60*F and Emerson HHT MODEL273/375, the following device descriptor is required. If the
MODEL273/375 you use does not support the device descriptor, update the internal software of
MODEL273/375. For details, refer to the MODEL275/375 instruction manual.
