Example
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 main run: R4 = -0.1 * 10^-5
$R[6]=1.874EX8 ; Assignment in main 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)

1.1.4 Predefined user variables: Link variables
Function
Link variables can be used in the context of the "NCU-Link" function for cyclic data exchange
between NCUs which are linked on a network. They facilitate data-format-specific access to
the link variables memory. The link variables memory is defined both in terms of size and
data structure on a system-specific basis by the user/machine manufacturer.
Link variables are system-global user variables which can be read and written in part
programs and cycles by all NCUs involved in a link if link communication has been
configured. Unlike global user variables (GUD), link variables can also be used in
synchronized actions.
On systems without an active NCU link, link variables can be used locally on the control as
additional global user variables alongside global user variables (GUD).
