StringToArray / StringToArrayU

Function - Copies the characters of a STRING to an array of SINT.

Inputs

SRC : STRING Source STRING
DST : SINT Destination array of SINT small integers (USINT for StringToArrayU)

Outputs

Q : DINT Number of characters copied

Remarks

In LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung. In IL, the input must be loaded in the current result before calling the function.

This function copies the characters of the SRC string to the first characters of the DST array. The function checks the maximum size destination arrays and reduces the number of copied characters if necessary.
