3.12 Word-for-Word Changes
Many changes to the program that do not modify the size of the program are considered word-for-
word changes. Examples include changing the type of contact or coil, or changing a reference
address used for an existing function block.
The following are word-for-word changes:
▪
Switching between two symbolic variables
▪
Switching between a symbolic variable and a mapped variable
▪
Switching between a constant and a symbolic variable
3.12.1
Exception: Symbolic Variables
Creating, deleting, or modifying a symbolic variable definition is not a word-for-word change.
