Error/Status Offset
-1 or 0 to 3935
This parameter defines the database location where the module status data will be
stored. If set to -1, data not placed in database.
Failure Flag Count
0
through
65535
This parameter specifies the number of successive transfer errors that must occur before
halting communication on the application port(s). If the parameter is set to
0
, the
application port(s) will continue to operate under all conditions. If the value is set larger
than
0
(
1
to
65535
), communications will cease if the specified number of failures occur.
Initializing Output Data
Y
ES
or
N
O
This parameter determines if the output data for the module should be initialized with
values from the processor. If the value is set to
N
O
(0), the output data will be initialized to
0. If the value is set to
Y
ES
(1), the data will be initialized with data from the processor.
Setting this option to
Y
ES
requires associated ladder logic to pass the data from the
processor to the module.
2.2.2 [HART PORT x]
The [HART PORT
x
] sections of the
configuration file set the HART channel
communication parameters, define the protocol specifics and set the command list
parameters. The parameters are the same for all ports. The command list for each HART
channel is entered in a different section of the file.
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.
Preambles
5 to 20
This parameter sets the number of preambles to be transmitted before each message is
sent from the channel. The value of 5 is normally utilized for the parameter. It can be set
to a value from 5 to 20.
Primary Master
Y or N
This parameter determines if the specific HART channel will emulate a primary or
secondary master. You can have only one of each type on a HART network. If you plan
on using a handheld device (secondary master), you must set the parameter to 'Y'. If the
parameter is set to 'Y', the channel will act as the primary master. A value of 'N' will set
the channel to act as a secondary master.
