Care should be taken when editing a script program on a working site

Issue

Care should be taken when editing an Automation Server script program in a working system

Environment

Automation Server Script program

Cause

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.
As below

 After editing the Numeric Input line using a reserved word, this line bindings are broken

Resolution

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
