Quantity structure
Explanations concerning the NC/PLC interface are based on the absolute maximum number of
the following components:
● Mode groups (DB11)
● Channels (DB21, etc.)
● Axes/spindles (DB31, etc.)
Data types
The control provides the following data types that can be used for programming in part
programs:
Type Meaning Range of values
INT Signed integers -2.147.483.648 ... +2.147.483.647
REAL Numbers with decimal point ≈ ±5.0*10-324 … ≈ ±1.7*10+308
BOOL Boolean values TRUE (≠0) , FALSE (0)
CHAR ASCII characters and bytes 0 ... 255 or -128 ... 127
STRING Character string, null-terminated Maximum of 400 characters + /0
(no special characters)
AXIS Axis names All axis names available in the control
system
FRAME Geometrical parameters for moving, rotating, scaling, and
mirroring
---
Arrays
Arrays can only be formed from similar elementary data types. Up to 3-dimensional arrays are
possible.
Example: DEF INT ARRAY[2, 3, 4]
Number systems
The following number systems are available:
● Decimal: DEF INT number = 1234 or DEF REAL number = 1234.56
● Hexadecimal: DEF INT number = 'H123ABC'
● Binary: DEF INT number = 'B10001010010'
Querying REAL variables
We recommend that querying REAL or DOUBLE variables in NC programs and synchronized
actions is programmed as limit value evaluation.
Example: Querying the actual value of an axis for a specific value
Program code Comment
DEF REAL AXPOS = 123.456
IF ($VA_IM[<axis>] - 1ex-6) <= AXPOS <= ($VA_IM[<axis>] + 1ex-6) ; actual position
... == AXPOS

Note
Industrial security
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Products and solutions from Siemens constitute one element of such a
concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the Internet if and to the extent such a connection is necessary and
only when appropriate security measures (e.g. using firewalls and/or network segmentation)
are in place.

2.1 Introduction
2.1.1 Programmed contour and tool path
Workpiece dimensions are programmed directly (e.g. according to the production drawing).
Therefore, tool data, such as milling tool diameter, cutting edge position of the turning tool
(counterclockwise/clockwise turning tool) and tool length, does not have to be taken into
consideration when creating the program.
The control corrects the travel path
When machining a workpiece, the tool paths are controlled according to the tool geometry so
that the programmed contour can be created with any tool.
So that the control can calculate the tool paths, the tool data must be entered in the tool
compensation memory of the control. Only the required tool (T...) and the required offset data
record (D...) are called via the NC program.
While the program is being processed, the control fetches the offset data it requires from the
tool offset memory, and corrects the tool path individually for different tools:

2.1.2 Tool length compensation
The tool length compensation compensates for the differences in length between the tools
used.
The tool length is the distance between the tool carrier reference point and the tool tip:

T Tool carrier reference point
P Tool tip
This length is measured and entered in the tool compensation memory of the control together
with definable wear values. From this data, the control calculates the traversing movements in
the infeed direction.
Note
The correction value of the tool length depends on the spatial orientation of the tool.
2.1.3 Tool radius compensation
The contour and tool path are not identical. The milling tool or cutting edge center point must
travel along a path corresponding to the tool radius that is equidistant from the contour (tool
center point path). To do this, while executing the program, the control shifts the programmed
tool center point path – based on the radius of the active tool (tool offset memory) – so that the
tool cutting edge traverses precisely along the programmed contour.
