Hello,
I have a question about S7 and how to get the current values from the plc and store them to the offline version so that when I make changes to the software, I don't have to go back to the HMI and re-enter the values that were last used. Is it so that I always have to go to the data block and then change the initial values to the values that are currently being used in the online plc so that they are updated or I can read them somewhere and then copy them back to the data block during the download. These values are things like setpoints that can change from time to time. I don't want to upload a copy of the plc and then have to search through all the data blocks that don't have any comments and the copy the initial values to the original plc program before downloading it after I have made several changes in the program. Thanks for your help!
Best Regards,
PK
