Assignments to R-parameters and use of R-parameters in mathematical functions:
Program code Comment
R0=3.5678 ; Assignment in preprocessing
R[1]=-37.3 ; Assignment in preprocessing
R3=-7 ; Assignment in preprocessing
$R4=-0.1EX-5 ; Assignment in the main program run: R4 = -0.1 * 10^-5
$R[6]=1.874EX8 ; Assignment in the main program run: R6 = 1.874 * 10^8
R7=SIN(25.3) ; Assignment in preprocessing
R[R2]=R10 ; Indirect addressing using R-parameter
R[(R1+R2)*R3]=5 ; Indirect addressing using math. expression
X=(R1+R2) ; Traverse axis X to the position resulting from the sum of
R1 and R2
Z=SQRT(R1*R1+R2*R2) ; Traverse axis Z to the square root position (R1^2 + R2^2)

3.1.1.3 Predefined user variables: Global arithmetic parameters (RG)
Function
In addition to the channel-specific R parameters, the user has access to global R parameters.
They exist once within the control unit and can be read and written from all channels.
Global R parameters are used, for example, to transfer information from one channel to the
next. Another example concerns global settings that should be evaluated for all channels, such
as the overhang of the raw part from the spindle.
