10 SLC 500™ Chassis–Based Processors

Publication 1747-2.39

The table below summarizes the SLC 500 processor channel

connections.

Protocol Options

Ethernet TCP/IP Protocol

Standard Ethernet, utilizing the TCP/IP protocol, is used as the

backbone network in many office and industrial buildings.

Ethernet is a local area network that provides communication

between various devices at 10 Mbps. This network provides the

same capabilities as DH+ or DH–485 networks, plus:

• SNMP support for Ethernet network management

• optional dynamic configuration of IP addresses using a

BOOTP utility

• SLC 5/05 Ethernet data rate up to 40 times faster than SLC

5/04 DH+ messaging

• ability to message entire SLC 5/05 data files

• much greater number of nodes on a single network possible

compared to DH–485 (32) and DH+ (64)
