I am required to do online changes to an existing application running on a S5-135U processor. I know that the unit seems to boot from the EEPROM card, because with the card missing, the processor remains in a faulted condition.
Is it possible to make changes for the processor only, and not the EEPROM? I always want to revert back to the original program that is stored on the eeprom. It seems that when the EEPROM is loaded/inserted, the program cannot be modified. Is this true?
I am actually only changing data words, so the changes are minor.
Also, when I use the TEST Block Status, I can only seem to see the very first highlighted rung. If I want to go to the next segment, the rungs are no longer highlighted, even though I am in TEST mode still. Is this normal, or how do I see the other rungs in the PB highlighted like the first?
Sorry, I am using Siemens S5 V6.65 Software
