1747 - L532C SLC 5/03 fault

Hi guys,

I am having an issue with SLC 1747-L532C.

It loses its program when it loses power.

So i downloaded a program again and put the key in RUN mode.

I got a fault and it says "The required memory module is absent or S:1/10 or S:1/11 is not set as required by the program."

Can someone tell me how to fix this issue?

Thanks
