An indicator system comprises at least one display based indicator (DBI; 6a, 6b,...) the configuration of which is uniquely identified by an idenifier (USI). The configuration is stored in a library of virtual indicators comprising one or more product profiles defining an overall product setup. There is a setup and protection device and a backup master (DBI-BM; 4) which provide for protected (re-)configuration of the DBI. Hereby it is achieved that if one DBI has to be replaced during operation of a system, this new DBI which is not previously recognised in the system will automatically or after user acknowledge receive the USI from the DBI-BM as soon as it starts to connect to the system and communicate with the DBI-BM. |
