Aggressive Mode in Secure Authentication subsystem.
Critical FCs File Number in Secure Authentication
This parameter is supported only in MicroLogix 1400 Series B controllers.
This file number is used to define the list of the critical function codes in Secure
Authentication. A critical function code should be defined in a word element in
this file. The maximum number of element in this file should not exceed 32(the
maximum number of the function codes that can be defined).
The value of this parameter is N file only. Valid range is 0, 7, 9 to 255. Default
value is 0.
When this file number is configured to 0 and there is no configuration file
assigned, some function codes are considered as critical by default. See the table
below for the critical function codes. When this file number of this parameter is
not 0 and it is a valid N data file, all function codes are considered as non-critical.
In this case, you must define all critical function codes in this file.
Note that the function code 0(FC_CONFIRM) is considered as critical once the
file number is configured newly. If you don't want the function code 0 to be
considered as critical, the number of elements in the file should be adjusted and
the element value 0 should not be in any elements.
