    CONFIGURATION One of the many advantages of Fieldbus is that device configuration is independent of the configurator. The LD292 may be configured by a third party terminal or operator console. Any particular configurator is therefore not addressed here. This section describes the characteristics of the blocks in the LD292. They follow the Fieldbus specifications, but in terms of transducer blocks, the input transducer block and display, they have some special features on top of this.
