Note
Comments on the individual return values
(1) Fixed, standardized addresses are recognized as DIN addresses. The following
definitions for geometry axes apply for NC addresses with adjustable identifiers:
A, B, C for specified rotary axes, E is reserved for extensions and
I, J, K, Q, U, V, W, X, Y, Z for specified linear axes.
The axle identifiers can be programmed with an address extension and can be written for the
test, e.g. 201 = STRINGIS("A1").
The following addresses cannot be written with an address extension for the test and always
deliver the fixed value of 400.
Example 400 = STRINGIS("D") or specification of an address expansion where
0 = STRINGIS("M02") results in 400 = STRINGIS("M").
(2) Cycle parameter names cannot be checked with STRINGIS.
(3) NC address letters G, H, L, M defined as macros are identified as macros.
Valid NC addresses without address extension with the fixed value of 400
NC addressed D, F, G, H, R and L, M, N, O, P, S, T are valid. Then
400

D as tool correction, cutting edge number (D function)
F as feed (F function)
G is defined as G code (not the path condition in this case)
H stands for auxiliary function (H function)
R is defined as system parameter and
L stands for sub-routine call-up, M stands for additional
function, N stands for sub-block,
O is free for extensions,
P stands for number of program executions,
S stands for spindle speed (S function),
T stands for tool number (T function).
