G–5Communicating with Devices on an Ethernet Network
Publication 1747-6.2
There are two ways to configure the SLC 5/05 Ethernet channel 1.
The configuration can be done via a BOOTP request at processor
powerup, or, by manually setting the configuration parameters using
RSLogix 500 Programming Software. The configuration parameters
are shown below and the configuration procedures follow.
Parameter Description Default Status
Diagnostic File
Number
The file number of the diagnostic counter for this channel. A Diagnostic File Number value of
zero means that no diagnostics file has been configured for this channel. The Diagnostic File
Number must be an integer within the limits of 7, 9–255.
0 read/write
MSG
Connection
Timeout
The amount of time (in ms) allowed for a MSG instruction to establish a connection with the
destination node. The MSG Connection Timeout has 250 ms resolution and a range from 250 to
65,500.
15,000 ms read/write
MSG Reply
Timeout
The amount of time (in ms) that the SLC 5/05 will wait for a reply to a command that it has
initiated via a MSG instruction. The MSG Reply Timeout has 250 ms resolution and a range
from 250 to 65,500.
3,000 ms read/write
Inactivity
Timeout
The amount of time (in minutes) that a MSG connection may remain inactive before it is
terminated. The Inactivity Timeout has a 1 minute resolution and a range from 1 to 65,500
minutes.
30 minutes read/write
IP Address
The SLC 5/05 internet address (in network byte order). The internet address must be specified
to connect to the TCP/IP network.
0 (undefined) read/write
Subnet Mask
The SLC 5/05 subnet mask (in network byte order). The Subnet Mask is used to interpret IP
addresses when the internet is divided into subnets. A Subnet Mask of all zeros indicates that
no subnet mask has been configured.
0 read/write
Broadcast
Address
NOT SUPPORTED AT THIS TIME. The SLC 5/05 broadcast address (in network byte order). The
Broadcast Address is used in sending multicast messages. A Broadcast Address of all zeros
indicates that no broadcast address had been configured. In this case, the network code will
choose a valid broadcast address when needed for that current subnet.
0
Gateway
Address
The address of a gateway (in network byte order) that provides connection to another IP
network. A Gateway Address of all zeros indicates that no gateway has been configured.
0 read/write
BOOTP Enable
The BOOTP enable switch. When BOOTP is enabled, the SLC 5/05 will attempt to learn its
network related parameters at powerup via a BOOTP request. There must be a BOOTP server
on the network capable of responding to this BOOTP request. When BOOTP is disabled, the
SLC 5/05 will use the locally configured network related parameters (IP Address, Subnet Mask,
Broadcast Address, etc.).
1 (enabled) read/write
Hardware
Address
The SLC 5/05 Ethernet hardware address.

Refer to the documentation provided with your programming
software.
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 EthernetLink.
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.
