¹Not recommended for use, but possible with limitations. Data blocks of channels and axes/
spindles that have not been activated can be used by the user, but this can result in conflicts
when upgrading or migrating the basic PLC program.
²If you use SINUMERIK Safety Integrated (F-PLC), this number range is used for automatically
generated F-blocks by default. You can adapt the number range used by the F-system, but you
must select a sufficiently large range of numbers.
