IP Filter
If the IP Filter Function Enable checkbox is selected, devices whose IP addresses are listed in the table
will be allowed to communicate with the CPU module, and the CPU module will discard data packets sent
from devices whose IP addresses are not listed in the table. The steps of setting the function are as
follows. Sixteen groups of IP address at most can be listed in the table.
•
Static ARP Filter
Users can use this function to set MAC addresses and corresponding IP addresses. The MAC address of
every device is unique. If the MAC address of device A is known, the MAC address can be bound to the
IP address assigned to device A. The CPU module will regard the IP address as the exclusive address of
device A. Even if device B is assigned the same IP address, the CPU module does not respond to device
B. The steps of setting the function are as follows. Sixteen groups of addresses at most can be listed in
the table.
