Installing ACP Lonworks
88
NOTE
!
When you connected the ACP Lonworks and PC through a cross cable, but you cannot
access the ACP Lonworks
• Check IP address of the ACP Lonworks and IP address of the PC.
Ex) If IP address of the ACP Lonworks is 192.168.1.101 and Net mask is 255.255.255.0,
check if the first three digits of the IP address of the PC is the same as the first three
digits of the IP address of the ACP Lonworks.
In such case, the IP address of the PC shall start with 192.168.1, and it shall be
different from the IP address of the ACP Lonworks. Set as follows, and try again.
- Setting of the ACP Lonworks
IP address: 192.168.1.112
Gateway address: 192.168.1.1
Subnet Mask: 255.255.255.0
- Setting of the PC
IP address: 192.168.1.113
Gateway address: 192.168.1.1
Subnet Mask: 255.255.255.0
• Check the status of the Ethernet cable (LAN cable).
NOTE
!
When PC and ACP Lonworks are connected together in a hub or a switch hub, and you
cannot access the ACP Lonworks.
• If it is right after changing the IP setting of the ACP Lonworks, reset the power of the ACP Lonworks.
• If it is right after connecting LAN cable to the hub or switch, it may take time for the hub or
the switch to recognize the ACP Lonworks. In such case, it may help to turn off and turn
on the power of the hub or the switch.
• Check the status of the Ethernet cable (LAN cable).
• Check ARP table of the PC to see if the IP address of the ACP Lonworks correctly
corresponds to the MAC address. If duplicate MAC addresses correspond to one IP
address, or if different address from the MAC address of the PC is output, there may be a
host with the same IP address as the IP address of the ACP Lonworks. In such case, the
IP address of the ACP Lonworks or the IP address of the corresponding host shall be
changed.
