A system for parameterizing field devices of an automation or control system includes a higher-ranking unit, which is connected via a first communication link based on a first field bus protocol to a communication interface module. The module is connected via a second communication link based on a second field bus protocol to at least one field device. In the higher-ranking unit, sub-blocks are generated and stored from a data structure for configuring the field device that is stored in a device description file for the field device. A first network service transmits the parameters of the field device from the higher-ranking unit via the first communication link into a first functionality of the module that operates as a slave function. A further functionality integrated into the module evaluates parameters of the field device that are stored in sub-blocks and combines the parameters to form a single configuration block.
