Abstract: Supporting multiple languages in the operation and management of a Process Control System. According to one aspect, a user may request a change of language in which a user interface is provided and the data elements in that language are copied from a reference database to a master database. The data required for the user interface is then provided from the master database. Due to the presence of data in multiple languages, the switch from one language to another may be easily accomplished. According to another aspect of the present invention the control strategies in a first language in a first control system can be exported and later imported to control strategies in a second language in a second control system. The reference database in the second control system may be used to translate the elements, while importing the translated control strategies in the master database of the second control system.
