1–4 SLC 5/05 Ethernet Processor Features
Publication 1747-10.4
The processors include a 3-position keyswitch on the front panel that
lets you choose from three modes of operation: Run, Program, and
Remote. You can remove the key in any of the three positions.
!ATTENTION: Depending on the size of your user
program, the processor can take up to 2.5 seconds to
change modes when you change the position of the
keyswitch from RUN to PROG or to REM. Do not use
the keyswitch in place of a hardwired master control
relay or an emergency-stop switch.
RUN Position
This position places the processor in the Run mode. The processor
scans/executes the ladder program, monitors input devices, energizes
output devices, and acts on enabled I/O forces. You can only change
the processor mode by changing the key position. You cannot
perform online program editing.
To change the mode to Run, turn the key from PROG or REM to
RUN. When the key is in the RUN position, you cannot use a
programmer/operator interface device to change modes.
PROG Position
This position places the processor in the Program mode. The
processor does not scan/execute the ladder program, and the
controller outputs are de-energized. You can perform online
program editing. You can only change the mode by changing the
key position.
To change the processor mode to Program, turn the key from REM
or RUN to PROG. When the key is in the PROG position, you
cannot use a programmer/operator interface device to change
modes.
REM Position
This position places the processor in the Remote mode: either the
REMote Run, REMote Program, or REMote Test mode. You can
change the processor mode by changing the keyswitch position or by
changing the mode from a programmer/operator interface device.
You can perform online program editing in this position.
To change the mode to REM, turn the key from RUN or PROG to
REM. When the key is in the REM position, you can use a
programmer/operator interface device to change modes.

Important: The SLC 5/05 processor contains a 10Base-T, RJ45
Ethernet connector which connects to standard Ethernet
hubs via 8-wire phone jack cable. To access other
Ethernet mediums, use Ethernet hubs that can be
connected together via fiber, thin-wire, or thick-wire
coaxial cables, or any other physical media
commercially available with Ethernet hubs. In addition,
media converters are commercially available to convert
10Base-T to other Ethernet media.

When to use straight-through and cross-over pin-out:
•SLC 5/05 Ethernet port to 10Base-T Ethernet hub cables utilize a
straight-through pin-out (1-1, 2-2, 3-3, 6-6).
•Direct point-to-point 10Base-T cables, with cross-over pin-out
(1-3, 2-6, 3-1, 6-2), connect the SLC 5/05 Ethernet port directly
to another SLC 5/05 Ethernet port (or a computer 10Base-T port).
Cables
Shielded and non-shielded twisted-pair 10Base-T cables with RJ45
connectors are supported. The maximum cable length between an
SLC 5/05 Ethernet port and a 10Base-T port on an Ethernet hub
(without repeaters or fiber) is 100 meters (328 feet). However, in an
industrial application, the cable length should be kept to a minimum.
Install RSLogix500 programming software and RSLinx
communication software. Refer to your software package’s
documentation for installation instructions. Be sure to use the
version of the software listed below. Earlier versions of the software
do not support the SLC 5/05 processor.

channel. The Diagnostic File Number must be an integer within the limits of 7, 9–255. 0 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 SLC 5/05 waits for a reply to a command it 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
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
IP Address The SLC 5/05 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 SLC 5/05 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. 0 read/write
Broadcast
Address
NOT SUPPORTED AT THIS TIME. The SLC 5/05 broadcast address (in network byte order). The
Broadcast Address is used in sending multicast messages. A Broadcast Address of all zeros
indicates that no broadcast address was configured. In this case, the network code chooses a
valid broadcast address when needed for that current subnet.
0
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 was configured. 0 read/write
BOOTP Enable
The BOOTP enable switch. When BOOTP is enabled, the SLC 5/05 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 BOOTP is disabled, the
SLC 5/05 uses the locally configured network related parameters (IP Address, Subnet Mask,
Broadcast Address, etc.).
1 (enabled) read/write

Configuration Methods

3–2 Configuring the Ethernet Channel for Local Communication
Publication 1747-10.4
The following step-by-step procedure shows how to set up the
SLC 5/05 and establish local communication on an Ethernet
network. You need to assign a unique IP address for your processor.
This procedure also shows how to create a ladder program for an
SLC 5/05 processor and download it via the RS232 COM port on
your computer to channel 0 (RS232) on the SLC 5/05. You can use
the 1747-CP3 Programmer Cable to make the physical connection.
Important: For this configuration method, you must first download
a program to the SLC 5/05 (via RS232) before you can
establish Ethernet communications.
Finally, this procedure assumes that you have previous experience
with SLC 500 processors and RSLogix500 programming software.
If you do not, the following publications will help with the SLC 500
hardware and the instruction set. For the software (RSLogix500 and
RSLinx), use the online HELP screens to guide you through
developing a program and configuring channel 0 communication
parameters.
•SLC 500 and MicroLogix 1000 Instruction Set Reference Manual,
publication 1747-6.15.
•SLC 500 Modular Hardware Style Installation and Operation
Manual, publication 1747-6.2.
Define SLC 5/05 Processor and I/O Modules
1. Start RSLinx software.
2. When the RSLinx window appears, click on the
“Communications” pull-down menu and select “Configure
Drivers”.
3. In this step, you will configure RS232 driver.
In the “Configure Drivers” window, select “RS232 DF1 Devices”
and click on the “Add New” box. The “Configure Allen-Bradley
DF1 Communications Device” window appears.
Select the communications port you wish to use. This is the PC
serial port COM1 through COM9.
Under Device Type, select “SLC–CH0” and “CRC error
checking”.
If you have an RS232 cable connected between the selected COM
port on your PC and channel 0 on your SLC 5/05, you can click
on “Auto-configure” to define your interface parameters.
