Parameter Definition - Siemens SINUMERIK 880 Programming Manual

7 Parameters
7.1 Parameter programming
All addresses can be assigned a parameter instead of a value.
L F
N5 Z = R5
The word structure of the various addresses must be observed (decimal notation or use of
sign does not apply to all addresses).
Incorrect:
R1= 51120.98
H = –R1
This numerical value is not possible at address H (Alarm 3000 "General programming
error")
7.2

Parameter definition

Parameter definition is used to assign certain numeric values with signs to the various
parameters.
The parameters can be defined either in part programs or in subroutines.
R1 = 10 L F
Parameter definition, subroutine call and switching functions may be written in a single block.
The value defined for a parameter is assigned directly to the address.
Example:
% 5772
N1...

.
N37 R1=10. R29=–20.05 R5=50.

While executing programs in several channels, the same central R
parameters must not be accessed simultaneously. This is avoided by a
