4 CFG File: [HART PORT x] Section
The [HART PORT 0], [HART PORT 1], [HART PORT 2], [HART PORT 3] [HART PORT
4], [HART PORT 5], [HART PORT 6] and [HART PORT 7] sections of the
DFCMHART.CFG file are used to set the HART channel communication parameters,
define the protocol specifics and set the command list parameters. The parameters are
the same for all 8 sections. The command list for each HART channel is entered in a
different section in the file. The table below lists the parameters defined in this section:

Enabled: Yes or No This flag specifies if the channel on the module will be
utilized. If the parameter is set to No, the channel will not be
used. If the parameter is set to Yes, the channel will be used
supporting the HART protocol.
Preambles: 2 to 50 This parameter defines the number of 0xFF characters
(preambles) that will be placed at the start of each HART
frames.
Enable Handheld: Yes or No This parameter enables or disables the use of handheld in
the channel. If the parameter is set to No, the ProLinx module
will not let other master to take data from the channel. If set
to Yes, it is possible to place other master in channel. With
this option in N the best throughput is achieved on the
channel.
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 mSec
which corresponds to the Primary Master. If set to No, then
this time is 380 mSec which corresponds to the Secondary
Master.
Short Address Retries: 0 to 10 This parameter specifies the number of times a command
addressed with short address will be retried if it fails.
Long Address Retries: 0 to 10 This parameter specifies the number of times a command
addressed with long address will be retried if it fails.
Retries After Error: 0 to 10 This parameter specifies the number of times a command will
be retried if it fails and the device to which the command is
addressed is in error.
Poll Time After Error: 0 to 65535 This parameter sets the time to wait to execute a command
again if it failed to respond for the retries number. This facility
can improve communication throughput on the HART
network.
DB Address Status 0-3999 This is the database address to use to place the device
status.
Command Count: 0 to 100 This parameter specifies the number of commands to be
processed for the port.
