6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.12.1 NC setting data (NC SD)
R parameters
700 parameters per channel are available for the whole system and
600 central parameters:
parameters R0 to R699 are channel-specific,
parameters R700 to R1299 apply to all channels.
Structure and application of R parameters:
Channel 1 to channel 4
R0 to R49
Typical application per channel:
Input of cycles and subroutines.
R50 to R99
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.
R100 to 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.
R200 to R219
Assigned internally (cycle converter)
R220 to R239
WS800 compiler
R240 to R299
Internal assignment plant.
R300
Stack pointer for @040, @041, @042, @043
R301 to R599
Stack area for @040, @041, @042, @043
R600 to R699
Reserved for user
R700 to R999
Typical application:
Higher level memory for all NC channels, e.g. for
buffering target positions used by another channel.
R1000 to R1299
Reserved for user
R10000 to R10019
Reserved for user for the function ”Select part program
for editing”.
