Ethernet Ports
LAN 1 connects to the uppermost RJ-45 connector. It is not switched. LAN2 connects to the three
lower RJ-45 connectors. They are switched internally.
The embedded Ethernet interfaces automatically senses the link data rate (10 Mbps or 100 Mbps),
communications mode (half-duplex or full-duplex), and cabling arrangement (straight-through or
crossover).
The embedded Ethernet LAN 1 port may be used to communicate with PME programming
software using the Service Request Transport Protocol (SRTP, a proprietary GE protocol, used
primarily for communication with the programmer).
To establish Ethernet communications between the PME programming package and the CPU, you
first need to set an IP address.

Note: LAN2 will not be operational unless it is configured from the programmer with a valid IP
address.
A typical application will take advantage of the two independent LANs. The dedicated LAN 1 port
will be used for communications with plant-level or supervisory layers. The switched LAN 2 will
be used to communicate with devices over PROFINET within the manufacturing cell or process.
