Latest video from @say2avi channel. 

1) This is easiest procedure for Siemens OP77B Or any similar generation such as OP77A backup.


2)The same process can be used for restoration also. 

3) Here we have used a 128 MB storage capacity Siemens MMC card

4) Only drawback is ,the Siemens MMC cards are a bit expensive and a bit susceptible to data corruption if the data retrieval in  computer from the MMC is not done properly. 

5) While reusing the same MMC for the backup procedure for a new device avoid formatting the MMC  using the Desktop/Laptop at all. It will prevent the MMC from double identical partition etc. 

6) In the video we can see, after giving the permission for backup procedure, the MMC itself is getting formatted via the HMI itself. It is confirmation for the point no. 5 itself. 

7) Viewers can see the previous videos of the channel & understand the entire methods and procedures for the backup/restore procedure for a Siemens Simatic  OP HMI devices.
