I had a program wiped out and when I downloaded the program the system wasn't working at the bigining I thought the backup was corrupted, after analysing the program.. I had to reintialize all the timers and pid
the backup has two meaning, one is the only program back up, this is without the online data uploaded and backup, this is not enough. The second is to upload the DB/or snapshot the online data into the offline DB, plus the code program backup.
If you select "program" then the situation will be the same as S7-1500 PLC, means that the program will be only in the card, card is the load memory. Then CPU will only own online live data, at this mode, CPU only plays the work memory.
@@electricalautomation ok thanks. In your case the cpu 1200 have its own Load memory and therefore you are using memory card only as "Transfer" Does 1500 not have its own load memory like 1200?
@@genantamtam9364 S7-1500 does not have its own load memory, it must use card. But S7-1200 has its own load memory 4MB. that is the reason S7-1200 is very great for the middle and small size machine.
This make me think i should get one for my automation class, in this format they could be pretty nice next to a M221
Enjoy it!
Thanks, very detail and helpful. 👍
Glad it was helpful!
Please how to do back up in mode “program”?

@@electricalautomationthank you, that's exactly what happened
Good video and thanks alot 👍.
One question... if i chose memory card type: "program" and not "Transfer". Were is this "Program" mode used?

@@electricalautomation thanks for the answer.
Have a great day
@@genantamtam9364 You too! Welcome!
very helpful details video.. thank you
Glad it was helpful!
Perfect presentation 👍
Thanks watching! I am also glad I demonstrated the 'online data issue' and 'password case'. They are also common cases in daily work
how many siemens cpu have own memory ?
You can check the specification section in the CPU manual and find the 'load memory' size
Excellent my friend
Thanks Bro
I love u .u r the best mr
Thanks and has been a while without seen you comments, Haha
Thank you!
Welcome!
