Data classes in the PLC
Assigning program blocks in data classes is used to efficiently upgrade or commission a
SINUMERIK control. Here, a distinction is made between three data classes:
● Manufacturer (M) is allocated by the machine manufacturer during construction.
● Individual (I) is allocated by the machine manufacturer during the first commissioning
(values for this specific machine).
● User (U) is set by the end customer (values associated with the particular process). You
cannot assign a different data class to the main program or to subroutines.
