4.8 Configuration Data
This section contains a listing of the parameters and their definitions for the
MVI46-DFNT module configuration.
[Section]/Item Value Range Description
[MODULE] Configuration header for general module information
Module Name: Up to 80
chars
Name of the module for use on reports. Use this
parameter to identify your module in your system.
M1 Write Size 0 to 4000 This parameter limits the M1 data transferred from the
processor to the module. The module application
automatically adjusts the size to an even 50-word
boundary as this is the minimum data transfer size for
the application. For example, a value of 199 would
automatically be adjusted to 200. This feature improves
the transfer of data from the processor to the module.
Failure Flag
Count:
0 to 65535 This parameter specifies the number of successive
transfer errors that must occur before the
communication ports are shut down. If the parameter is
set to 0, the communication ports 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.
Initialize Output
Data:
0 or 1 This parameter determines if the output data for the
module should be initialized with values from the
processor. If the value is set to 0, the output data will
be initialized to 0. If the value is set to 1, the data will
be initialized with data from the processor. Use of this
option requires associated ladder logic to pass the data
from the processor to the module.
DFNT Server File
Size
100 or
1000
Sets the maximum file size (100 or 1000) for the
servers.
Float Write Start 0 to 3950
(multiple of
50)
Starting address within the database of the MVI46-
DFNT module where floating point data will be stored.
The module will then automatically swap the byte order
of this data, so that it is displayed correctly within the
SLC data tables. This is necessary as the MVI46-DFNT
module and the SLC processor use a different floating
point data formats.
Float Write Count 0 to 4000
(multiple of
50)
Sets the size (words) of the float area defined in Float
Write Start parameter.
[Section]/Item Value Range Description
[DF1 Pass-Through Server Port 1] Start header for the pass-through server
Enabled: Y or N This parameter determines if the pass-through server
will be utilized.
Service Port
Number:
1 to 65535 Service port number to be associated with this server.
The number assigned must match that used by the
client software to establish the connection.
