Not recommended for use, but possible with limitations. Data blocks of channels, axes/
1
spindles and tool management functions that have not been activated can be used by the user,
but this can result in conflicts when upgrading or migrating the PLC basic program.

Generating blocks at runtime on the NCU

In specific circumstances, some of the basic PLC program blocks are generated by the NCU at
runtime:
● If you do not load them explicitly onto the NCU
● If you load blocks with an unexpected size onto the NCU, for example because blocks do not
match the machine configuration (e.g. DB20 [DB20] or AL_MSG [DB2]) or because of a
different runtime version.
