Fundamental Principles of NC Programming
2.2 Language elements of the programming language
Example:
X7
X4=20
CR=7.3
S1=470
M3=5
The extended address notation is only permitted for the following direct addresses:
Address
X, Y, Z
I, J, K
S
SPOS,
SPOSA
M
H
T
F
In the case of extended address notation, the number (index) can be substituted by a
variable for addresses M, H and S and for SPOS and SPOSA. The variable identifier is
enclosed in square brackets.
Example:
S[SPINU]=470
M[SPINU]=3
T[SPINU]=7
