3.2
[HART PORT x]
The configuration file sections [HART PORT 0] through [HART PORT 3] (for 4 channel
modules) or [HART PORT 0] through [HART PORT 7] (for 8 channel modules) set HART
channel communication parameters, define the protocol specific parameters, and set the
command list parameters. The parameters are the same for all channels. The command
list parameters for each HART channel are entered in a different section in the
configuration file.
3.2.1 Enabled
Y or N
This parameter enables or disables the specific HART channel. If the parameter is set to
"Y", the channel will be utilized. If set to "N", the channel will not be used.
3.2.2 Preambles
2 to 50
This parameter defines the number of 0xFF characters (preambles) that will be placed at
the start of each HART frames.
3.2.3 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.
3.2.4 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.
3.2.5 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.
