Siemens R/GUD: R variables and global data

R, RG and GUD variables used for parameterization and global data in Siemens programs.

For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.

Family: Siemens
Machine: Milling, Turning, Mill-turn
Risk: High
Example: R1=10 / R[10]=20 / GUD
