I have an S7 414 with a 1MB card. The line has been running fine but I needed to added some analog inputs to one of the ET200SP profinet modules. I physically added the module, then added to the offline hardware configuration. I then went to download the new hardware configuration, I got a warning of a bottleneck and needed to compress. I told it to compress. It compressed then started the download, put the processor in stop and started loading. It then popped up and said memory was full and download would be aborted. After this, the processor would not go back to run. I tried downloading the original hardware configuration with the same results. I then turned off power to plc, pulled the memory card. This cleared the card. I then tried to download again with 0% showing on load memory ram. I started with hardware configuration this increases load memory to 34%. I then download all DB's, which increases load memory ram to 69%. I then try to load OB's, FB's and FC's. I run out of memory before all are loaded.
Somehow there is a program on it after the cleared memory is put back in but it is not the correct program.
I have ordered a 2MB card but really want to know why it is needed now?
I have 4 questions,
1) If I can't load it back in, how did it all get there in the first place and be operational?
2) Since it was all there in the beginning why won't it go back on?
3) What or where is the program on the card coming fromwhen it says 0% load memory ram used?
4) What am I doing wrong?
HHHHHHEEEEEELLLLLPPPPP!!!!!!!!!
