Two functions are available for monitoring quality data in combination with ibaQDR: DelayLengthL and DelayLengthV. Both functions allow you to align measurement signals from remote sources with respect to product length. The distance between the signal sources determines the value of 'LengthDelay'.
The difference between these functions is the used reference signal: DelayLengthL uses a length signal and DelayLengthV a speed signal.
DelayLengthL
DelayLengthL('Expression','Length','LengthDelay')
Arguments
|
'Expression' |
Input signal |
|
'Length' |
Length signal (in m) |
|
'LengthDelay' |
Delay (in m) |
Description
This function delays the input signal 'Expression' by the time required to cover the distance 'LengthDelay' (in m). This distance is converted to a delay time using the length signal 'Length' (in m).
Example
The example shows the time delay of a length delay of 1.5 m at the offset shown below.
DelayLengthV
DelayLengthL('Expression','Speed','LengthDelay')
Arguments
|
'Expression' |
Input signal |
|
'Speed' |
Speed signal (in m/s) |
|
'LengthDelay' |
Delay (in m) |
Description
This function delays the input signal 'Expression' by the time required to cover the distance 'LengthDelay' (in m). This distance is converted to a delay time using the speed signal 'Speed' (in m/s).
