SLC 5/05 Ethernet Processor
Features
This chapter:
• describes SLC 5/05 processors and Ethernet communication
• describes SLC 5/05 performance considerations
• illustrates SLC 5/05 hardware features
• explains processor status LED operation
• explains keyswitch operation
Ethernet is a local area network that provides communication
between various devices at 10 Mbps. The physical communication
media options for the SLC 5/05 are:
• built-in
– twisted pair (10Base-T)
• with media converters or hubs
– fiber optic
– broadband
– thick-wire coaxial cable (10Base-5)
– thin-wire coaxial cable (10Base-2)
See page 2–4 for more information on Ethernet physical media.
The SLC 5/05 supports Ethernet communication via the Ethernet
communication channel 1 shown in the drawing below.
