| 摘要 |
The invention relates to a method for maintaining a production installation comprising several field devices (F1, F2, F3), some or all of which are connected to a control system (L) via a data bus (D). The field devices (F1, F2, F3) are recorded in a manufacturer database (HG-DB) with a manufacturer-specific identification and manufacturer-specific information that is relevant to their maintenance and in a customer database (IB-DB) with a customer-specific identification and customer-specific information. An electronic database request for maintenance criteria takes place using both databases (HG-DB) and (IB-HG). This allows both manufacturer information and customer information to be taken into account during the maintenance process.
