Critical Function Code in Secure Authentication
This critical function code in the DNP3 Slave configuration page is used to define the list of the
critical function codes in Secure Authentication. A critical function code should be defined by
clicking the number icon to change it between Critical and Non-critical.
The following table shows the default state of the function codes that are defined in
Connected Components Workbench software.
Function Codes
Function Code Critical FCs Function Code Critical FCs
0 (0x00) non-critical 20 (0x14) critical
1 (0x01) non-critical 21 (0x15) critical
2 (0x02) critical 22 (0x16) non-critical
