3.2.6 Command Count
0 to 99
This parameter sets the number of user commands to be utilized. The first command in
the list is always reserved for the auto-poll command so the user should configure this
value considering one command for the auto-poll. For example, if the user configures two
commands, the command count parameter should be set as 3. This parameter can be
set from 0 to 99. If the parameter is set to a value other than 0, commands should be
present in the [HART PORT x COMMANDS] section.
3.2.7 Auto-Poll Code
p2p or Not used
This parameter sets the auto-poll mode of the channel. If the parameter is set to "p2p",
the module will automatically poll device 0 in point-to-point mode. If the parameter is set
to "Not used", the auto-polling option will be disabled and only commands in the
command list will be utilized for the channel. In the auto-poll mode, the module will
automatically execute HART commands 0, 3, 13, 14, and 15.
3.2.8 Auto-Poll DB Address
0 to 3700
This parameter sets the starting address for the data obtained by the auto-poll feature.
Each device on a channel requires 50 words in the database. The data area selected
must not overlap any portion of the database used by other channels or the module.
3.2.9 Auto-Poll Swap Float
0 to 3
This parameter swaps the floating-point data values received by the auto-poll feature.
Swap Code Description
0 None - No Change is made in the byte ordering (1234 = 1234)
1 Words - The words are swapped (1234=3412)
2 Words & Bytes - The words are swapped then the bytes in each word are
swapped (1234=4321)
3 Bytes - The bytes in each word are swapped (1234=2143)
Depending on the host processor using the data, the proper swap code must be utilized
to present the data in the correct format.
3.2.10 Max Device Count
1 to 15
This parameter sets the maximum number of slave devices to be utilized for the auto-poll
feature. In point-to-point mode, the parameter should be set to a value of 1.
