Configuration Via BOOTP

Configuring the Ethernet Channel for Local Communication

Switch to the Ethernet Network and Go ONLINE

1. Connect your computer and your SLC 5/05 processor to any
standard Ethernet hub. You need an Ethernet communication
card to connect your PC to the Ethernet hub.
2. In RSLogix, click on the "Comms" pull-down menu and select
"System Comms". In the "System Options" window, change the
"Driver" to "AB_ETH-1" and "Apply". Click on "Who Active".
3. The "Who Active" window appears, showing your Ethernet node.
Your computer will be "STA 63 AB_ETH-1" with its assigned
name. Your SLC 5/05 will be "STA 1" with its assigned name.
Double-click on the "STA 1" icon. Then go on-line with your
SLC 5/05 via Ethernet.
4. If you have a second SLC 5/05 processor, set it up following the
same procedure as for the first SLC 5/05, but using its own
unique IP address. Also assign this address to the next available
STA address in RSLinx.
5. If you have two SLC 5/05 processors, and you have entered the
one-rung MSG into both of them, you may put them both in the
"RUN" mode and monitor N7:60 in either processor. The value
of N7:60 should increment with each tick of the Real Time Clock
in the other SLC 5/05 processor.
If you only have one SLC 5/05, you cannot send MSGs, but you
are on-line with your processor via 10 Mbps Ethernet.
BOOTP is a standard protocol that TCP/IP nodes use to obtain
start-up information. By default, the SLC 5/05 broadcasts BOOTP
requests at powerup. The BOOTP valid parameter remains clear
until a BOOTP reply has been received. BOOTP lets you
dynamically assign IP Addresses to processors on the Ethernet link.
To use BOOTP, a BOOTP server must exist on the local Ethernet
subnet. The server is a computer that has BOOTP server software
installed and reads a text file containing network information for
individual nodes on the network.
The BOOTP request can be disabled by clearing the BOOTP Enable
parameter in the channel Configuration File. When BOOTP Enable
is cleared (disabled), the SLC 5/05 uses the existing channel
configuration data.
Important: If BOOTP is disabled, or no BOOTP server exists on
the network, you must use SLC 500 programming
software to enter/change the IP address for
each processor. See page 3–2 for that configuration
procedure.
