IP Filter

Unauthorized access can be prevented by identifying the IP address of an access source.
Rules used for identifying an IP address can be set in module parameters of GX Works3. (Page 57 Security settings)
For more details on this function, refer to the following:
MELSEC iQ-F FX5 User's Manual (Ethernet Communication)
Behavior when denying an IP address
When an IP address is denied by rules set in GX Works3, an FX5-OPC discards the packets from the IP address.
When the access destination IP address of the discarded IP packets satisfies both of the following conditions, an event
(0810H) is notified with detailed information containing the access source address. (Page 85 Event List)
• It is the own address of the FX5-OPC.
• It is not a broadcast address or multicast address.
If a series of discarded IP packets are sent from a single IP address, only the first event is notified.
The notified event can be checked with the diagnostic function of GX Works3. (Page 77 Module diagnostics)
