5.2.6.2 Connection problem after exchanging an F 8628X
The ARP entry on the PC must be deleted if the new F 8628X has the same IP address as
the old F 8628X.
Otherwise the new F 8628X with the same IP address cannot be connected to the PADT (PC).
Example: Delete the ARP entry of an F 8628X with the
IP address
192.168.0.67.
• Start the "Dos Shell" on the PADT (PC).
• Enter the command
arp -d 192.168.0.67.
5.2.6.3 Check the connection to the F 8628X using "Ping"
• Start the "Dos Shell" on the PADT (PC).
• Enter the command Ping 192.168.0.x.
• Messages generated by "Ping":
• Ethernet connection is OK : "Reply from 192.168.0.x: bytes = 32 time < 4ms..."
If ELOP II connection is available check the resource settings in ELOP II.
• Ethernet connection is not OK: "Request timed out."
Check the wiring, routing entry etc.
5.2.6.4 The F 8628X determines its IP address in accordance with the following
priorities
1. The IP address is determined from the Resource ID (Res-ID) of the user program that
is loaded in the F 865x.
The Res-ID of the user program always has a higher priority than the F 865x ID settings
(DIP-switch 1-7).
2. The IP address is determined from the F 865x ID settings (DIP switches 1-7), if the Res-
ID cannot be determined from the current user program's resource name and switch
ID_IP is activated on the F 8628X (switch 1/6 ON).
3. IP address of the "Basic Configuration"
If no IP address can be determined using the Res-ID or ID (switch 1/6 OFF) as de-
scribed in the first two cases, the last IP address determined on this F 8628X is used.
Note If all steps described in this chapter have been followed and the
F 8628X does not respond, check if other participants can be
accessed using the PC's netword card.
