Write Register Count
Range 0 to 4000
This parameter specifies the number of registers to transfer from the processor to
the module. Valid entry for this parameter is 0 to 4000.
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.
