Care should be taken when editing an Automation Server script program in a working system
Automation Server Script program
If a script program "Numeric Input", "Numeric Output" or "Numeric Public" line is modified, but includes a syntax error or a reserved word, then saved, the binding for this line may be broken.
After editing the Numeric Input line using a reserved word, this line bindings are broken
Always be extra careful when modifying scripts running live plant. In this case it would be better to add a new extra "Numeric Input", "Numeric Output" or "Numeric Public" line, rather than modifying an existing one.
The binding below are not broken
NOTE This issue was fixed in v1.7
