HiGEOCHRIS. I do not know of a specific manual covering information that you want. However some FAQ's that can provide more information on topics of your interest. Apart from the indication on the powesupply (LED's) you get alarm messages in PCS7 OS. These messaged are created by the driver blocks in PCS7. For e.g you will get messages like "<Rack & Slot number> Battery Failure" Go through the help of FB 89PS block available in PCS7 library for more information. Go throughthis FAQto get an idea, how this block might actually be working (and how to implement a similar functionality with Step 7). With S7 400 CPUs (I don't know about 300) there is an option of external battery backup. I think you can use it to preserve your program when you are replacing your power supplies. More information on Battery backup is given inthis FAQ Hope it helps regards.
