parameters R0 to R699 are channel-specific,
parameters R700 to R1299 apply to all channels.
Channel 1 to channel 4
R0 to R49
R00 R00
. . . .
Typical application per channel:
. .
Input of cycles and subroutines.
R49 R49
R50 to R99
R50 R50
Typical application per channel:
For calculations within cycles and subroutines.
The same local parameters may be used for nested
. . . .
subroutines. When cycles or subroutines are called with
. .
@040 to 043, an R parameter stack saves the data used
so far and stores them after return to the calling program.
R99 R99
R100 to R199
R199 R199
Typical application per channel:
Memory for data which must be accessible for the main
. . . .
. .
programs and subroutines. R100 to R109 are assigned if
Siemens tool management is used. R110 to R199 are
assigned for Siemens measuring cycles.
