NETLink PRO ETH
The entry for the security query is case-sensitive, that is, upper and lower
case must be correct.
After the security query has been correctly answered, you have write-access
to all parameters that are implemented for TCP security.
Is the TCP access list switched on by typing ‘ON’ to the field ‘
TCP access
list ON/OFF
’, only TCP connections with addresses configured in the table
entries ‘
TCP address 1
’ to ‘
TCP address 12
’ are able to communicate to the
NETLink PRO without restrictions (white list).
The pattern for a legal ip address is something like ‘
192.168.4.49
’. To delete
an ip address the pattern ‘
OFF
’ is necessary.
IP addresses without access rights are only allowed to read some information
at the web interface. Using PPI, MPI or PROFIBUS functionalities are not
possible. Also the configuration tool is not working.
