SLC 5/05 and PC Connections to the Ethernet Network

TCP/IP is the mechanism used to transport Ethernet messages.
The SLC 5/05 processor uses TCP/IP to establish sessions and to send MSG
commands. Connections can be initiated by either a client program
(INTERCHANGE or RSLinx application) or a processor. Refer to the MSG
instruction operation in chapter 12 for information on how connections are
established using the MSG instruction.
The SLC 5/05 Ethernet connector conforms to ISO/IEC 8802-3 STD 802.3
and utilizes twisted pair media. Connections are made directly from the SLC
5/05 to an Ethernet hub or switch. The network setup is simple and cost
effective. The typical network topology is pictured below, as well as an
alternate point-to-point connection using an RJ-45 cross-over cable.
