software.
Configuration Via BOOTP BOOTP (bootstrap protocol) is a low-level protocol that TCP/IP nodes
use to obtain start-up information. By default, the SLC 5/05 processor
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
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...65,500.
15,000 ms read/write
MSG Reply
Timeout
The amount of time (in ms) that the SLC 5/05 processor 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...65,500.
3000 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...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
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 processor attempts 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 processor uses the locally configured network related parameters
(for example, IP Address, Subnet Mask, Broadcast Address).
