1785-6.5.19 November 1998
Configuring the Interface Module for Ethernet Communication 3-3
Enter configuration information in the appropriate fields.
After entering the channel 3A configuration information, either
accept edits or access status information about channel 3A.
This field: Specifies: Configure by doing the following:
Diagnostics file The file containing the
channel’s status information Cursor to the field, type an unused integer file number (10-999), and press [Enter].
The system creates an integer file 44 words long.
ATTENTION: Do not assign a diagnostic file number that is the I/O status file you assigned to
another communication channel or any other used file. Unpredictable machine action can result.
Important: You must define a diagnostics file for a channel configured for anything but unused
(even if you are not using the channel) if you want status information for that channel.
Ethernet address The interface module’s Ethernet
hardware address
Display only.
Assigned by Allen-Bradley and cannot be changed.
Displayed as a set of 6 bytes (in hex), separated by colons.
IP address The interface module’s Internet
address Cursor to the field, and enter an address in this form:
a.b.c.d Where: a, b, c, d are between 1–254 (decimal)
You must specify the IP address to have the interface module connect to the TCP/IP network. Do
not use 0 or 255 as a, b, c, or d in the IP address.
BOOTP enable Whether BOOTP is enabled Cursor to the field and specify No (for manual configuration).
Before you disable BOOTP, make sure you have an IP address specified. With BOOTP set to No ,
the interface module uses the parameters that you specify locally.
To enable BOOTP, see “Using BOOTP to Enter Configuration Information” on page 3-4.
MSG conn timeout The number of milliseconds
allowed for an MSG instruction
to establish a connection with
the destination node Cursor to the field, and enter a timeout period in milliseconds. (The interface module rounds to
the nearest 250 ms.) The valid range for a timeout period is 0–65,535 ms.
The default is 15,000 ms.
MSG reply timeout The number of milliseconds the
Ethernet interface waits for a
reply to a command it initiated
(through an MSG instruction) Cursor to the field, and enter a timeout period in milliseconds. (The interface module rounds to
the nearest 250 ms.) The valid range for a timeout period is 0-65,535 ms.
The default is 3,000 ms.
Inactivity timeout The number of minutes of
inactivity before the connection
is closed Cursor to the field, and enter a timeout period in minutes. The valid range for a timeout period is
0–65,535 minutes.
The default is 30 minutes.
Broadcast address The broadcast address to
which the processor should
respond
See the Enhanced and Ethernet PLC-5 Programmable Controllers User Manual, publication
1785-6.5.12 for information about how to configure these advanced Ethernet functions.
Subnet mask The processor’s subnet mask
(used when network has
subnets)
Gateway address The IP address of the gateway
that provides a connection to
another IP network
Link ID A DH+ link number
Use the link ID number to
identify the processor when
configuring a ControlLogix
system using the ControlLogix
Gateway software. Enter a link ID number. The valid range is 0-199.
Only enter a Link ID number if you plan to configure multihop MSG instructions through a
1756-DHRIO module in a ControlLogix chassis. See chapter 4 for more information.
