Predefined user variables: Arithmetic parameters (R)

Function
Arithmetic parameters or R-parameters are predefined user variables with the designation R,
defined as an array of the
index, e.g.
When using synchronized actions, the $ sign must be included as a prefix, e.g.
Syntax
When used as a preprocessing variable:
R<n>
R[<expression>]
When used as a main run variable:
$R<n>
$R[<expression>]

, and without array index, e.g.
R[10]
Identifier when used as a preprocessing variable, e.g. in the part program
Identifier when used as a main run variable, e.g. in synchronized actions
Type:
Range of values: For a non-exponential notation:
: Number of the R-parameter
Type:
Range of values: 0 - MAX_INDEX
: Array index
Any expression can be used as an array index, as long as the result of the
expression can be converted into the
data type. For historical reasons, notation both with array
, is permitted for R-parameters.

± (0.000 0001 to 9999 9999)
Note:
A maximum of 8 decimal places are permitted.
For an exponential notation:
± (1*10 to 1*10
-300
Note:
• Notation: <Mantisse>EX<exponent> e.g. 8.2EX-3
• A maximum of 10 characters are permitted including
sign and decimal point.

Note
MAX_INDEX is calculated from the parameterized
number of R-parameters: MAX_INDEX =
