Protocol Configuration 625
Ethernet Driver
The MicroLogix1400 supports Ethernet communication via the Ethernet
communication channel 1. Ethernet is a local area network that provides
communication between a variety of network devices at 10/100 Mbps.
TCP/IP is the mechanism used to transport Ethernet messages. The
MicroLogix1400 processor uses TCP/IP to establish sessions and to send
MSG commands. Connections can be initiated by either a client program
(INTERCHANGE or RSLinx application) or a processor. Refer to
Communications Instructions on page 393 for the MSG instruction
operation to see how connections are established using the MSG
instruction. The MicroLogix1400 Ethernet connector conforms to ISO/IEC
8802-3 STD 802.3 and utilizes 10/100Base-T media. Connections are made
directly from the MicroLogix1400 to an Ethernet hub or switch. The
network setup is simple and cost-effective.
There are two ways to configure the MicroLogix1400 Ethernet channel 1.
The configuration can be done via a BOOTP or DHCP request at
processor power up, or by manually setting the configuration parameters
using RSLogix 500/RSLogix Micro Programming Software (refer to
Example 5 - Configuring an Ethernet/IP Message on page 432).
RTS Send
Delay (x20
ms)
Allows you to select the delay between when RTS is raised and the transmission is initiated. Specify
the RTS Send Delay value in increments of 20 ms. Valid range is 0…65535.

Address
IP Address 1…254 (zero and 255 are reserved for broadcast purposes.)
The processor's internet address. You must specify the IP address to enable the processor to connect
to the TCP/IP network. You can specify the address manually, or enable BOOTP or DHCP (located in
the Protocol Control section of this dialog) to provide the address.
