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:

BOOL
Truth values TRUE (1) and FALSE (0)
1, 0
CHAR
ASCII characters
Corresponding to code 0 to 255
STRING
Character string, number of characters in [...]
Maximum of 200 characters (no special
characters)
AXIS
Axis names only
All axis identifiers in the channel
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.
