C7-633 can't get it to work with a memory card

The situation is we have a C7-633 –part 6ES7 633-2BF02-0AES which appears to work fine when we don’t try to use a memory card which I’ve programmed ok with the HMI part on MPI 1 and CPU on MPI 2.
However If I boot with a blank memory card in the slot the CPU drops off the MPI network and I can only see the HMI. The HMI ends on this error - $551 AS address 2 not possible.
If I use our Field PG to program the card with the same program and then insert it into the device the same thing occurs.
If I power the device without memory card and download the program then insert the memory card. The option to Download to memory card becomes available but this doesn’t appear to do anything apart from causing the same error.
The problem is only whenever I try to use a memory card with our c7-633. I have two which I’ve been trying a 64k 700-951-0kf00 and a 256k 6ES7 951 1KH00-0AA0. Both look to be working in field PG one I know is good as I’ve used this year on another job and PLC.

I suspect I have a faulty unit which does not work with memory cards.

If I use our Field PG to program the card with the same program and then insert it into the device the same thing occurs.

This might be a silly question, but do you perform an overall reset after inserting the memory card with the program on it? This can be as simple as removing the battery with power on, powering down, and powering up again. Or, you can use the MRES function on the PG in STEP 7. Also, make sure power is off when removing/inserting the memory card!!

The proper action to copy the downloaded program to the memory card on board the CPU is "Copy RAM to ROM..."

Your getting the system data AND all your blocks to the flash card right?

I don’t know what I was doing wrong the first time but I’ve had another go and this time I managed to get the thing to reset whilst the memory card was inserted so thy that It didn’t drop off the network. Then downloaded the PLC and and then did the download to memory now.
