RSLogix 500 Programming
Software Refer to the online documentation provided with your programming 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 MicroLogix 1100 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.
SMTP Client
Enable (Series
B only) The SMTP Client service enable switch. When SMTP is enabled, MicroLogix 1100 is
capable of transmitting e-mail messages generated by a 485CIF write message with a
string element. There must be a SMTP server on the network capable of processing
e-mail service. This provides an extremely versatile mechanism to report alarms, status,
and other data-related functions. 0 (disabled) read/write
Auto Negotiate
and Port
Setting When Auto Negotiate is disabled (unchecked), the Ethernet speed/duplex is forced to
either 10 Mbps/Half-duplex, 10 Mbps/Full-duplex, 100 Mbps/Half-duplex, or 100
Mbps/Full-duplex, as selected in the Port Setting field.
When Auto Negotiate is enabled (checked), the Port Setting Field allows you to select
the range of speed/duplex settings that the MicroLogix 1100 will negotiate.

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 MicroLogix 1100 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
(Series B only) 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
