Data types
The following elementary data types are used in the control system:
Type Meaning Value range
INT Signed integers ±(2
31
- 1)
REAL Figures with decimal point acc. to IEEE ±(10
-300
… 10
+300
)
BOOL Boolean values: TRUE/FALSE TRUE ≠ 0; FALSE = 0
CHAR 1 ASCII character corresponding to the code 0 … 255
STRING Character string, number of characters in [...], maximum of
200 characters
Sequence of values with 0 ... 255
AXIS Axis identifier Axis identifier for all channel axes
FRAME Geometrical parameters for translation, rotation, scaling,
and mirroring
Arrays can only be formed from similar elementary data types. Up to two-dimensional arrays are possible.
Quantity framework
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.)
The actual possible number of components listed above for a specific product can be found
in the following ordering documentation:
