ErrorBits parameter

If several errors are pending simultaneously, the values of the ErrorBits are displayed with
binary addition. The display of ErrorBits = 16#0000_0003, for example, indicates that the
errors 16#0000_0001 and 16#00000_002 are pending simultaneously.
For Polyline the errors output at the ErrorBits parameter are divided into two categories:
● Errors with error messages ErrorBits < 16#0001_0000
● Errors with error messages ErrorBits ≥ 16#0001_0000
Errors with error messages ErrorBits < 16#0001_0000
If one or more errors with error messages ErrorBits < 16#0001_0000 are pending, enable
output ENO is not changed. The output value can be determined as follows despite this
error:
● Interpolation calculation when Reset = FALSE.
or
● Output of SubstituteOutput when Reset = TRUE.

Data type Default
INT 0
INT 2
Description
Selection of the output value if the input value
lies outside the defined x-values
0 = Maintain slope
•
1 = y-value of the first/last point
•
Permissible value range: 0 to 1
Index of the next x-value
Used for monitoring the index of the points that
are being used for the current interpolation
calculation.
The following condition applies:
WorkingData.Point[NextXIndex-1].x < Input ≤
WorkingData.Point[NextXIndex].x
Do not change this value manually.
