Our machine stopped working due to the SLC-500 (1747-L40A) had CPU red fault LED on.
Major Error D:6=12h
Error Description: The ladder program has a memory error.
I cleared the fault but the fault returned whenever I tried to go online.
I downloaded the exact file to the SLC again and the CPU fault LED went away. And everything is good now. The file I used had been run on the same SLC500 for the last two months without a problem. There are four recipes and they were all alternated and used without a problem during the two months.
I searched online for a clue but could not find it.
Is the ladder program that is bad somehow?
Or is the memory module going bad?
Thank you
