Monitoring Major/Minor Faults and Fault Codes

When a fault occurs, the controller status screen in your programming software displays program file and rung number indicators that point to where the fault occurred.

Interpreting Major Faults

Displaying a Description of the Major Faults Clear the Faults by

•The status text that appears corresponds to the most significant fault when the cursor is not on the major fault status word.

•If the cursor is on a major fault word bit and that bit is set, the status text that appears corresponds to the bit that the cursor is on.

•If no bits are set, the message area is blank.

•Using the clear major-fault-function on the controller status screen of your programming software. When you clear major faults, the fault code, program file, and rung number fields are also cleared.

•Resetting individual bits. If you have more than one major fault and you reset a bit, the status text displays the next major fault message.

For a description of the major faults (S:11), see Appendix B.

Interpreting Minor Faults

Displaying a Description of the Minor Faults Clear the Faults by

•The status text that appears corresponds to the most significant fault when the cursor is not on the minor fault status words.

•If the cursor is on a minor fault word bit and that bit is set, the status text that appears corresponds to the bit that the cursor is on.

•If no bits are set the message area is blank.

•Using the clear minor-fault-function on the controller status screen of your programming software.

•Resetting individual bits. If you have more than one minor fault and you reset a bit, the status text displays the next minor fault message.
