Ethernet Ports
CPE100 provides two independent Fast Ethernet LANs. LAN1 has only one port and is
dedicated to the embedded Ethernet controller. LAN2 is comprised of 3 switched
ports, each configurable either as a second embedded Ethernet controller or as an
embedded PROFINET controller. Use PME to configure the operation of the ports.
All the Ethernet ports of both the LAN1 and LAN2 are capable of automatically sensing
the link data rate (10 Mbps or 100 Mbps), communications mode (half-duplex or full-
duplex), and cabling arrangement (straight-through or crossover).
To establish Ethernet communications between the PME programming software and
the CPE100, you
first
need to set a valid IP address.

LAN2
Default IP Address:
192.168.0.100
0.0.0.0
Subnet Mask:
255.255.255.0
0.0.0.0
Gateway:
0.0.0.0
0.0.0.0
Note:
•
LAN2 will not be operational unless it is configured from the programmer with a valid
IP address.
•
Care must be taken when assigning IP Addresses and subnet masks to each LAN so that
an overlapping IP subnet is not created. Intermittent or no Ethernet communication may
result if an overlapping IP subnet is created and the two interfaces are NOT connected
(cabled) to the same physical network.
•
By default, PME prohibits configuring both LAN interfaces on an overlapping IP subnet.
(This may be changed by going to Controller General Options and changing the Multiple
Embedded LANs on Same Subnet to Show as Warning.)
