However I also want to save theArchived program in PLC memory, when I save the program in memory card, it does not accept and mentions the space in the memory card is zero. I calculated and found that the zip file size is only 790KB, and PLC memory has only 1MB of program. IS there any way I can also save theArchivedprogram, or memory card is not functioning properly.

Hello lucky; What is the size of the MMC you are using now? What function do you use to transfer the data (zip file) to the MMC? Hope this helps, Daniel Chartier

How can you load projects to a memory card and back again to a PG/PC?

I see no reason why the Archived file should not be able to be saved in memory card, however since I have not much experienced such types of issue, hence I thought of sharing this information on the forum and find out what can be the reason. I am yet to find the cause and solution for this problem. Let me know if I can provide some more information. Thanks,
