Data translation tables allow the user to convert a tag value into another value. For example, they can be used to translate an integer value to a string value. The user could use it to:
● Translate recipe numbers into readable text.
● Translate error numbers into readable text.
● Translate string constants into values.
A translation table can be used in the following conditions:
● For upload, download or both directions.
● While downloading data that has unique source values.
● While uploading data that has unique destination values.
● While uploading and downloading data that has a unique source and destination value.
