2.2 [Module]
This section provides the module with a unique name, identifies the method of
failure for the communications for the module if the processor is not in run, and
describes how to initialize the module upon startup.
2.2.1 Module Name
0 to 80
characters
This parameter assigns a name to the module that can be viewed using the
configuration/debug port. Use this parameter to identify the module and the
configuration file.
2.2.2 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.
2.2.3 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.
2.2.4 Initialize Output Data
0 = No, 1 = Yes
This parameter is used to determine 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.
2.2.5 DFNT Server File Size
100 or 1000
Sets the maximum file size (100 or 1000) for the servers
