The command is sent continuously

2

Float DB

Address

300

The damping value response will be copied to the
internal database starting at word-address 300

(occupies addresses 300 to 301)

3

Poll Interval

0

The command is sent without any delay

4

Word Count

2

The command returns 10 words of floating point

data

5

Swap Code

3

The bytes in each returned floating point word are

swapped

6

Short Address 0

This command is sent to the Hart slave device using

short address 0

7

The command function 4 (WRITE DAMPING

VALUE) is used in this example

8

This command does not use this feature

14

DB Write

Address

800

The floating point value located at byte-address 800
(word-address 400) will be used as the damping

value to be written to the HART device

15

DB Swap Code 3

The bytes in each returned integer data will be

swapped

16

Byte Count

4

The command will write 4 bytes (2 words) to the

HART device, since the damping value uses floating

point format (2 words)

17

Fixed Data

This command does not use this feature

The user would have to verify that addresses 300 and 320 are located inside the

Read Data area (read from the MVI database to the PLC processor). Address

400 would have to be located inside the Write Data area (written from the PLC

processor to the MVI database).
