Need some insight into why this happened. After finally getting a VM to connect to a CPU 216 2 siemens processor, uploaded the program. made a change to an output being used due to one gone bad, and downloaded the program back in and all of a sudden nothing worked.
Troubleshot it down to the fact that all of the saved data for program settings was cleared, ie, Temp settings, delays, cycle timers, etc. so all retentive data that was supposed to be kept in place, it all went to 0.
I double checked what could have happened, set some data again, and uploaded, then downloaded and it didn't clear anything out this time. but then power cycling the machine cleared it back to 0, except that I thought these were supposed to be in the retentive ranges set in the program.
Is there some special setting in S7 Micro/win that i'm missing? do i need to do more than the download function with the blue arrow at the top? should i be using the store program to memory funtion or is that basically the same as having a second eeprom memory module installed for a second backup?
