DEL – Delay with initialization

Block SymbolLicensing group: STANDARD
PIC

Function Description
The DEL block implements a delay of the input signal u. The signal is shifted n samples backwards, i.e.

yk = ukn.

If the last n samples are not yet known, the output is set to

yk = y0,

where y0 is the initialization input signal. This can happen after restarting the control system or after resetting the block (R1: off on off) and it is indicated by the output RDY = off.

Inputs

u

Analog input of the block

Double (F64)

R1

Block reset

Bool

y0

Initial output value

Double (F64)

Outputs

y

Delayed input signal

Double (F64)

RDY

Ready flag indicating that the buffer is filled with the input signal samples

Bool

Parameter

n

Delay (number of samples). The resulting time delay is n TS, where TS is the block execution period.   0  10000000 10

Long (I32)

nmax

Limit for parameter n (used for internal memory allocation)   10  10000000 100

Long (I32)
