If the program has been set to read protect you will not be able to upload the program from the CPU into the KV LadderBuilder software. I seem to remember, however, that you can still go onlline and monitor. It's been a long time since I've dabbled with the Keyence KV series and I don't have one handy with which to test my recollection.

I've never used the Keyence Backup Tool software so I can't help you in any way with that.

If you have hardcopy (printout) of the PLC program, search through it for the MEMSW instruction. This is the instruction that enables/disables read and write protection of the PLC program (and a number of other things, also). This instruction is detailed in volume three of the "User's Manual". The discussion begins on page 3-92. If you do not have a manual it is available from the dowload section of this site.
