Configuration Parameters
Parameter Description Default Status
Hardware
Address The MicroLogix 1400 Ethernet hardware address. Ethernet
hardware
address read only
IP Address The MicroLogix 1400 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 MicroLogix 1400 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.
In this case, the controller assumes a Subnet Mask of 255.255.255.0. 0 (undefined) 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.
In this case, the controller assumes a Gateway Address of aaa.bbb.ccc.001, where aaa.bbb.ccc are
the first three octets of the configured IP Address. 0 (undefined) read/write
Default Domain
Name The default domain name can have the following formats:
’a.b.c’, ’a.b’ or ’a’, where a, b, c must start with a letter, end with a letter or digit, and have as
interior characters only letters, digits or hyphens. Maximum length is 63 characters. NULL
(undefined) read/write
Primary Name
Server This is the IP address of the computer acting as the local Ethernet network Primary Domain Name
System (DNS) server. 0 (undefined) read/write
Secondary Name
Server This is the IP address of the computer acting as the local Ethernet network Secondary Domain
Name System (DNS) server. 0 (undefined) read/write
BOOTP Enable The BOOTP enable switch. When BOOTP is enabled, the MicroLogix 1400 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 both BOOTP and DHCP are disabled,
the MicroLogix 1400 uses the locally configured network related parameters (IP Address, Subnet
Mask, Broadcast Address, etc.). 1 (enabled) read/write
DHCP Enable The DHCP auto configuration enable switch. When DHCP is enabled, a DHCP server automatically
assigns network related parameters to the MicroLogix 1400 when it logs into a TCP/IP network.
There must be a DHCP server on the network capable of allocating network addresses and
configuring parameters to newly attached device. When both BOOTP and DHCP are disabled, the
MicroLogix 1400 uses the locally configured network related parameters (IP Address, Subnet Mask,
Broadcast Address, etc.). 0 (disabled) read/write
SNMP Server
Enable SNMP enable switch. Check this to enable SNMP (Simple Network Management Protocol). 1 (enabled) read/write
SMTP Client
Enable The SMTP Client service enable switch. When SMTP is enabled, MicroLogix 1400 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 1400 will negotiate. Auto
Negotiate
enabled and
Port Setting.
10/100 Mbps
Full
Duplex/Half
Duplex 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 MicroLogix 1400 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. 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…65,500 minutes. 30 minutes. read/write
