The actual upper limit of the block number (DB) depends on the PLC CPU on which the selected
NCU is located. The data blocks of channels, axes/spindles and tool management functions that are
not activated may be assigned as desired by the user.

The data blocks of channels, axes/spindles and tool management functions that are not
activated may be assigned as required by the user.
