CompactLogix System Distance Ratings

Because the 1768 CompactLogix power supply works with the controller to power a 1768 system, the distance rating in a 1768 CompactLogix system differs from that in a 1769 CompactLogix system. In the 1768 system, the distance rating is the distance between 1769 I/O modules and the controller. In the 1769 system, the distance rating is the distance between 1769 I/O modules and the power supply.

Follow these requirements to determine proper placement of your 1768 controller, power supply, 1768 I/O modules, and 1769 I/O modules:

• Place the 1768-L4xx controller so that it is the last module

(furthest away from the power supply) in the 1768 backplane.

• The 1768 CompactLogix power supply distributes power from

the right side of the supply and must be the leftmost module in the system.

• Up to eight 1769 I/O modules can reside in the local bank.

• The local bank is powered by a 1768 power supply.

• Up to two remote banks of 1769 I/O modules may be

connected by using 1769-CRLx extension cables.

• Remote banks are powered by a standard 1769 power supply.

Publication

1768-IN004D-EN-P - December 2009

CompactLogix Controllers 9

• Up to eight 1769 Compact I/O modules can reside on each

side of a 1769 power supply in a remote bank. Consult the module’s specifications for its distance rating.

IMPORTANT

Never place a 1769 power supply in a local bank with a 1768 controller or a major fault will occur.

• The type of controller determines the maximum number of

1768 modules that can reside in the local bank and the maximum number of 1769 I/O modules that can reside in one local and up to two remote banks.

Clear a Major Fault

If the OK status indicator flashes red because of a recoverable major fault, clear the fault by following these steps.

1. Turn the controller keyswitch from PROG to RUN and back to PROG.

2. Go online with RSLogix 5000 software.

3. On the Controller Properties dialog box, click the Major Faults tab to find information about the fault.

If the OK status indicator is flashing red because of a nonrecoverable major fault, the controller:

• initially displayed a solid red OK indicator.

• reset itself.

• cleared the project from its memory.

• set the OK indicator to flashing red.

• produced a major recoverable fault and generated a

corresponding fault code in the RSLogix 5000 project.

– Fault code 60 means the CompactFlash card is not installed. – Fault code 61 means the CompactFlash card is installed.

Follow these steps to recover from fault code 60 or 61.

1. Turn the controller keyswitch from PROG to RUN and back to PROG.

2. Go online with RSLogix 5000 and download the project.

3. Change to REM RUN or RUN mode.

If the issue persists, record the status of the OK and RS-232 indicators before cycling power and contacting Rockwell Automation support.

Clear a Nonrecoverable Fault

If the OK status indicator is solid red, follow these steps to clear the fault.

1. Cycle power.

2. Download the project.

3. Change to REM RUN or RUN mode.

If the issue persists, record the status of the OK and RS-232 indicators before cycling power and contacting Rockwell Automation support.

Troubleshoot a Nonresponsive Module

Follow these steps to determine why a device may not be responding.

1. Verify that all I/O modules in your project are installed in the same order.

2. Verify that all devices have been updated to the latest major and minor firmware revisions.

3. Use RSLogix 5000 software’s online help to determine which module is not responding.

Troubleshoot System Power

The CompactLogix power supply works with the CompactLogix controller to provide power to the system. You must consider both when attempting to troubleshoot system power.

IMPORTANT

Before you disconnect, reconnect, or replace any component, make sure you have turned off power and allowed all system status indicators to turn off.

To troubleshoot system power issues, use the CompactLogix power supply PWR status indicator and the CompactLogix controller PWR and I/O PWR indicators. If the power supply is not operating properly, the controller will not operate properly either. You must first diagnose and correct any issues with the power supply before troubleshooting the controller.

1. Examine the power supply PWR status indicator.

2. If the power supply is operating properly and the power supply PWR status indicator is green, examine the controller PWR indicator.

3. If the controller PWR status indicator is green, examine the I/O PWR status indicator.

b. If the status indicator is green, one of the other modules in

the system is causing the red indicator.

5. Remove power and wait for all status indicators to turn off.

6. Reinstall the controller and check the power supply’s PWR indicator.

a. If green, remove power, wait for all status indicators to turn

off and reinstall 1768 modules one at a time until you identify the module causing the red indicator.

b. If red, replace the controller.
