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 1400 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.
Contact The Contact string which is specified by the SNMP client. The maximum length is 63 characters. read only
Location The Location string which is specified by the SNMP client. The maximum length is 63 characters. read only
Network Link ID The Link ID assigned to the MicroLogix 1400 by either an RSLinx OPC topic or by the routing table in
a 1756-DHRIO or 1756-DH485 module. The range is 0…199.
0 read/write
Starting Data
File Number
The first ASCII (A) file number in a contiguous block of 4-32 ASCII files (4 per User Provided Web
Page). The range is 9…252 (or 0 for disable).
0 read/write
Number of Pages The number of User Provided Web Pages, provided the Starting Data File Number is non-zero. The
range is 1…8.
1 read/write
DNP3 over IP
Enable
When DNP3 over IP is enabled (checked), the MicroLogix 1400 enables DNP3 over IP feature on
Ethernet channel. Power cycle is required for changes to take effect.
0 (disable) read/write
Modbus TCP
Enable
When Modbus TCP is enabled(checked), the MicroLogix 1400 enables Modbus TCP feature on
Ethernet channel. Power cycle is required for changes to take effect.
0 (disable) read/write
Disable
EtherNet/IP
Incoming
Connections
When EtherNet/IP Incoming Connections is disabled (checked), the MicroLogix 1400 does not allow
the incoming EtherNet/IP connection. However, MicroLogix 1400 can send the outgoing EtherNet/IP
commands to other EtherNet/IP devices. Power cycle is required for changes to take effect.
0 (disable) read/write
Disable
Duplicate IP
Address
Detection
When Duplicate IP Address Detection is disabled(checked), the MicroLogix 1400 does not send any
packets to the network to detect Duplicate IP on the same network.
