3.3.2 Preambles
2 to 50
This parameter defines the number of 0xFF characters (preambles) that will be
placed at the start of each HART frames.
3.3.3 Primary Master
Yes or No
This parameter specifies the Link Quiet / Slave Timeout. If set to Yes, the
selected Link Quiet / Slave Timeout is 305 milliseconds which corresponds to the
Primary Master. If set to No, then this time is 380 milliseconds which corresponds
to the Secondary Master.
3.3.4 Retry Count
0 to 10
This parameter sets the number of retries for a command if the command
response is not received from the slave device. This parameter is normally set to
a value of 3. The module will accept values of 0 to 10.
3.3.5 DB Address Status
-1, 0 to 3999
This parameter is utilized to set the database address in the module where the
status word for the channel will be placed. If the parameter is set to -1, the word
value will not be placed in the database. If a value from 0 to 3999 is set for the
parameter, the status word for the channel will be placed at the specified
database offset. This word is bit mapped with each bit representing a slave
device. The bit will be set if slave device has a communication error.
3.3.6 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.
