R0 to R49
R00
R00
Typical use for each channel: Assignment of
: .

cycles and subroutines
R49
R49
R50 to R99
R50 Typical use for each channel: For calculations within
R50
programs and subroutines. In the case of nested
subroutines, the same local parameters can be used.
An R parameter stack saves data hitherto used with
: .
: .
cycles or on subroutine call with @040 to 043 and
stores it after returning to the program that made
the call.

R100 to R199
R100
Typical use for each channel: Store for data to which
main programs and subroutines must have access.
: . : .
R100 to R109 are assigned if Siemens tool manage-
ment is used. R110 to R199 are assigned if Siemens
measuring cycles are used.
