In the 1200/1500 PLC system block, there is no instruction to convert character array into character string and character array into character array, so I developed a standard FB block in SCL language. The specific code is as follows, and the source code is required to add me qq584472557
1. Character array to string instruction
This block can convert the number of characters starting at any position of the character array into a string for output.
2. Convert a string to a character array
