315-2 DP Memory Bottleneck during download

Hi all,

I have problem regarding to memory bottleneck.

When I changed something in any FC, FB etc. and i tried to download, it appears bottleneck fault. I explained in the attached file.

Also, I tried to memory compress during cpu running. But it doesn't change anything.

Should I do this in stop mode? 

You can see details in the attached file.

Thanks,

Eren

Hello,

only few basic questions.

1. when you look to your prj, how much your blocks takes? Keep in mind that also some system blocks are also there.

2. Your MMC for CPU capacity?

3. how you did download? Explain pls steps.

4. is on your MMC also other blocks saved? This can simply comsupt also capacity. If you have all backups, try delete MMC via menu, maybe also format via Step7 menu.

Sry I can only imagine this for this moment, for sure check all. Point 4 take as last solution...

Hi.

Sounds silly, but did you close the editor before compressing? Also check the Programming with STEP 7 manual to see there correct procedure for compression.

 Hello,

1. When I checked program offline and online, almost it's same.

I found only 2 fb in online but it's not use, i can delete but their size only 130byte..

2. mcc capacity 128kb.

3. When I completed my modifications, I click to donwload symbol.

4. i didn't understand this topic, how can i check this?

Also, i guess i'll upgrade size of my MMC card. Does it has any procedure for this operation?

Thanks,
