ROSEMOUNT 644 CONFIGURATION
Configuration of the 644 can be performed using a Handheld Field Communicator or AMS Device Manager. Configure the sensor type and device units to “mV.” Configure the AI block of the 644 as follows:
1. Set the MODE_BLK.TARGET to OOS
2. Set CHANNEL to the transducer block configured for the analog input
3. Set XD_SCALE.EU_0 to 20 Set XD_SCALE.EU100 to 100
Set XD_SCALE.ENGUNITS to mV
4. Set OUT_SCALE to match the desired scale and units for the connected analog transmitter.
5. Flow Example: 0-200 gpm OUT_SCALE.EU_0 = 0 OUT_SCALE.EU_100 = 200 OUT_SCALE.ENGUNITS = gpm
6. Set L_TYPE to INDIRECT
7. Set the MODE_BLK.TARGET to AUTO

well i really dont know how to convert hart to FF but you solved my problem.
Thanks for the description.
Is there any device to convert FF signal to 4 to 20 ma or 1 To 5 V DC
In the 2nd figure, you have connected 5ohm resistor in parallel not in series, but in the first figure its connected in series.
Hi, in both figures the 5 Ohm precision resistor is connected in parallel of the Fieldbus Foundation (FF) device and in series within the Hart loop.
