Optionally, use the Description field to enter a description for the variable. If used, the Description text is exposed in other parts of the ACE interface (for example, through OPC). 9.

However, you are permitted to have two variables with the same name on two dif- ferent controllers. This allows you to reuse programs across controllers and maintain consistency within variable names.
