NOTE:
Before executing a Backup on a BM100 backup module make sure the
Write Protection switch is set to Unlocked.
If BM100 and BM2x0 are both installed B&R is automatically performed
only on the BM100 module.
BM2x0 can execute B&R only with Network up and running (network cable
connected).
QL500 can backup up to 10 nodes (Master + 9 slaves).
