Function
A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - 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
Remarks
In FFLD 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"Instruction list"
This is a low-level language and resembles assembly, 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.
ST Language
Q := StringToArray (SRC, DST);
FBD Language
FFLD Language
(* The function is executed only if EN is TRUE *)
(* ENO keeps the same value as EN *)

Op1: LD"Ladder diagram"
Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them
