In this video, you will learn about the standard CODESYS functions to work with Strings. There are several functions including LEN, LEFT, RIGHT, MID, CONCAT, INSERT, DELETE, REPLACE, and FIND.
In this video, I only explain how all these functions act on the strings, and in another video, I will show you how to use some of these functions to have an animated text field. Here is a brief explanation of those functions:
LEN: Provides the length of the input string as an integer value.
LEFT: Extracts a part of the input string (left side to the provided position)
RIGHT: Extracts a part of the input string (right side to the provided position)
MID: Extracts a part of the input string (given number of characters), starting at the given position
CONCAT: Combines two strings with each other and generates another string as its output
INSERT: Inserts a string within another one, starting from the given position and with the determined number of characters
DELETE: Removes the given number of characters starting from the given position
REPLACE: Replaces a part of the input string with another string
FIND: Finds the position of the first occurrence of a given string within the input string.
