from the IP address of the ACP BACnet. Set as follows, and try again.
-
Setting of the ACP BACnet
Subnet Mask: 255.255.255.0
-
Setting of the PC
Subnet Mask: 255.255.255.0
Check the status of the Ethernet cable (LAN cable).
Notes
When PC and ACP BACnet are connected together in a hub or a switch hub, and you
cannot access the ACP BACnet.
If it is right after changing the IP setting of the ACP BACnet, reset the power of the ACP
BACnet.
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 BACnet. 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 BACnet 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 BACnet. In such case, the IP address of the ACP
BACnet or the IP address of the corresponding host shall be changed.
