Siemens SINUMERIK 828D Function Manual page 6

Preface
Quantity structure
Explanations concerning the NC/PLC interface are based on the absolute maximum number of sequential
components:
• Mode groups (DB11)
• Channels (DB21, etc.)
• Axes/spindles (DB31, etc.)
Data types
The following elementary data types are used in the control system:
Type Meaning
INT Signed integers
REAL Figures with decimal point acc. to IEEE
BOOL Truth values TRUE (1) and FALSE (0)
CHAR ASCII characters
STRING Character string, number of characters in [...]
AXIS Axis names only
FRAME Geometrical parameters for moving, rotating, scaling, and
mirroring
Arrays can only be formed from similar elementary data types. Up to 3-dimensional arrays are possible.
