MicroLogix 1500 Controller Fault Question

[Zodic 0]

Good evening,

Just had a fault that caused the PLC to not run through the program. The fault was 0479H and I can't find anything on it. I cleared it via my computer and it is working fine currently with no issues. I've looked online and in the reference books with nothing I can find on this error. Any help is appreciated.

Thank you.

See pdf. Error code xx79.

The xx ( 4 in your case) is module #4.

I do not see the code in the pdf linked xx49

Edit: Ohhhhh I see it I think. XX79 and XX is equal to 04 with is the 4th module.

I am still new to lot of this what does it mean that the Fault Classification is Non-Recoverable. Also the I/O Module Status(IOS) file I am not sure what that is either.

Post the complete catalog number of the module.

Give me a moment to go grab it, but that is just the type of module your needing?

It helps to know the exact module part number.   
These kinds of fault codes usually are the result of a loose connection, or a power spike, or a damaged or defective module.

Be sure that the End Cap (1769-ECR, usually) is solidly in place on the Compact I/O assembly.

I couldnt find a model number, but I took a picture of the 4th module.

To find the model number of the module, open the swing door on the front...the A-B part number is on the lower part of the swing door

The model number is 1769-IF4XOF2. I apologize I am still learning a lot. Most of it is as stuff happens.

Checked the module and nothing out of the ordinary. Everything has been running since then as well. Thank you for all the help!
