Installation Requirements
Before you begin installing the system, take a moment to review these system
installation requirements.
Location
The ProcessLogix system is CSA certified and FM approved non-incendive
equipment for installation in Class I, Division 2, Group A, B, C & D hazardous
(classified) locations. The user must ensure all parts of the system, and any other
equipment in the Division 2 area, are listed for installation in a Class I, Division 2
hazardous (classified) location.
Removal and Insertion Under Power
Some ProcessLogix modules (e.g., I/O and communications modules) as well as the
1757-PLX52 Process Controller module have been designed to permit removal and
insertion under power (RIUP) without damaging the module or interrupting
backplane communications.
Any time electrical connections are made or broken, there is a potential for arcing
or sparking. Do not remove or insert any modules while they are still powered up
when you are in a hazardous (potentially explosive) environment.
ATTENTIO
N
!
The ProcessLogix RIUP feature does not apply to
installations that must conform to Division 2 hazardous
location requirements. Unless the location is known to be
non-hazardous, do not:
•connect or disconnect cables
•connect or disconnect removable terminal blocks
•install or remove modules

Connect Power
1. Use #14 AWG 75 °C copper wire.
2. Tighten terminals to a torque of 7 inch-pounds.
3. Connect L1 for the high side of line power.
4. Connect L2 for the low side of line power.
1. Remove the protective label from the top of the power supply.
2. Apply power by toggling the switch on the front of the power supply from
OFF to ON.
ATTENTIO
N
!
Turn off power lines before connecting power. Failure to
do so could cause injury to personnel and/or damage to
equipment.
IMPORTANT Make sure you mount the chassis and complete work on the
panel before you remove the protective label. The label protects
the power supply from metal shavings falling inside the power
supply and damaging it during operation.

Troubleshoot the Power Supply
The ControlLogix power supply has a green LED indicator that remains on during
normal operation. If the indicator is off during normal operation, try the following:
1. Verify that line voltage is within the specified range.
2. Make sure the input voltage jumper is in the proper position (see page 5).
3. If indicator remains off, cycle line power off.
4. Loosen the screws holding the power supply to the chassis.
5. Slide the power supply out so the rear connector is disconnected.
6. Wait 45 seconds and re-apply power.
7. If the indicator turns on, verify that the system module loads are within the
output rating of the power supply and re-install the power supply in the
chassis.
8. If the LED turns off, return the power supply to your local Rockwell
Automation distributor.
Installing the ControlNet Communications Module
Install the 1756-CNB module for ControlNet communications into slot 0 of the
chassis.
1. Align the module circuit board with the top and bottom guides in the
chassis.
2. Slide the module into the chassis. Make sure the module properly connects
to the chassis backplane.
TIP The module is fully installed when it is flush with the power
supply or other installed modules.
To remove the module, push down on the locking clips at the
top and bottom of each module. Slide the module out of the
chassis.

Setting up and Configuring the Server
To use the server (cat. no. 1757-PLXC) in your ProcessLogix system, you must:
•connect server hardware
•start and log in to the server
•verify RSLinxcommunication software configuration and the ControlNet
server address
•verify Ethernetadapter and TCP/IP address
Connect Server Hardware
1. To connect the server hardware, refer to the Dell PC startup documentation
that accompanied the server.
2. To install the 9904-KTCX15B card in your server, refer to the 9904-KTCX15B
installation instructions that accompanied your card.
3. Once you have connected the hardware, apply power to the server, and
ensure that it operates correctly.
Start and Log in to the Server
1. Apply power to the server (if you have not done so already).
2. At the login screen, type the following:
Verify RSLInx Communication Software Configuration
To communicate with ControlNet devices, your server must have:
•RSLinx communication software properly configured
•an operating KTC driver
After you have successfully logged on to your server for the first time, make sure
that RSLinx communication software is properly configured, and your server has a
valid address for communication with ControlNet devices. Each ControlNet device

must have a unique address. In this section, we show you how to verify that your
communication software is working properly and how to find the server address.
Start RSLinx software
To start RSLinx:
1. In your Microsoft Windows NTdesktop, select
Start⇒Programs⇒Rockwell Software⇒RSLinx.
RSLinx opens in about ten seconds.
2. Select Communications⇒Configure Drivers.
Verify RSLinx communication software configuration
Once you have started RSLinx, you can verify that it has been configured correctly.
When you select Communications⇒Configure Drivers in RSLinx, you see a screen
that looks like this one:
if you see this in the Configured Drivers
window then
AB_KTC-1 CNET MAC Addr:...RUNNING RSLinx is correctly configured on your system
AB_KTC-1 CNET MAC Addr:...NOT RUNNING RSLinx may not be configured correctly. See
page 13.

ProcessLogix Hardware 15
Publication 1757-5.1 - August 1999
Verify and record server ControlNet address
1. On the RSLinx Configure Drivers screen, double-click on this line in the
Configured Drivers window:
AB_KTC-1 CNET MAC Addr:...RUNNING
You see the Configure Allen-Bradley KTC(X) Device screen.
1. Verify that the ControlNet address is configured correctly. In the MAC ID
field, check that the MAC ID is equal to 20.
2. Close the Configure Drivers screen.
3. To close RSLinx, select File⇒Exit.
TIP The ControlNet address is called the MAC ID on some screens.

Publication 1757-5.1 - August 1999
Verify the Ethernet Adapter and TCP/IP Address
The ProcessLogix server uses Ethernet hardware and the TCP/IP protocol to
communicate with client user stations. Even if your system does not have a client
user station, you will need to install an adapter and configure a TCP/IP address for
proper communication.
Verify the Ethernet adapter
1. In your Microsoft Windows NT desktop, select Start⇒Settings⇒Control
Panel.
2. Double-click on the Network icon. You see the Network screen.
3. Click the Adapters tab. You see the Network Adapters screen.
IMPORTANT If your server and remote stations do not have Ethernet cards
installed, you can use the Microsoft loopback adapter provided
with the NT operating system. The loopback adapter is a
software program that emulates the operation of the Ethernet
card
TIP On this screen, adapter (1) is an Ethernet card. Adapter (2) is the
loopback adapter. Your configuration may vary.

ProcessLogix Hardware 17
Publication 1757-5.1 - August 1999
4. Verify that the configured adapter appears in the list. If it does not appear,
you may need to install and configure the adapter yourself. Refer to the
documentation accompanying the Ethernet card or loopback adapter for
more information.
Verify the TCP/IP address
Verify the TCP/IP address only if your system will communicate with remote
stations. Otherwise, skip this section.
1. From the Network menu, click on the Protocols tab,
2. In the Network Protocols field, double-click on TCP/IP Protocol.
3. On the TCP/IP Properties screen that appears, select the Ethernet adapter
you have installed.

4. Write down the information that is displayed in the IP Address and Subnet
Mask fields. You will need this information later when you connect other
computers to your server.
IP Address:________________Subnet Mask:________________
Depending on changes you made to your configuration, you may need to reboot
your system. Shut down all applications before rebooting the system.
5. To close the TCP/IP properties screen, click on Cancel.
6. To close the network program, click Cancel.
7. To close the Windows Control Panel, select File⇒Close.
Installing ControlNet Cabling
To install the ControlNet cabling for ControlNet communications, you will need:
•two 1786-TPS or 1786-TPR droplines
•two 1786-XT termination resistors
•one 1786-BNCP cable

ProcessLogix Hardware 19
Publication 1757-5.1 - August 1999
To install the cabling:
1. Connect a termination resistor on one side of each dropline.
2. Connect each dropline to a 1786-BNCP cable.
3. Connect the bottom of one dropline to the 1756-CNB module.
4. Connect the bottom of the other dropline to the 9904-KTCX15B card
installed in the server.
