When the user checks what the program is running on, they'll see the below error that says something like "1 routine err". This means the program is failing on a particular routine. The cause can be empty value fields like below, so make sure to check the program thoroughly for any empty value fields to resolve this. Another reason can be mismatched tag types. For example, in the DB Builder a tag/point can be a string, but was added/configured as a number in the program. Make sure the types match.
