The Rosemount 3420 Fieldbus Interface Module (FIM) was designed for users in facilities without fieldbus I/O. It enables installation of Foundation fieldbus devices with any host system, and provides access topredictive diagnostic information from the fieldbus devices, enablingasset management and performance optimisation within the AMS Suite: Intelligent Device Manager software. Process monitoring such as temperature and machinery monitoring, and many smaller discrete areas of process automation in the plant can be improved when automated with fieldbus devices. FIM uses web server technology to simplify commissioning, configuration and maintenance tasks. The scaleable architecture provides a maximum of four separate fieldbus segments, including power conditioners. Control can be shifted into the field, enabling tighter actionand higher production yields. External communications with any basicprocess control system are achieved using Modbus, HSE, and OPC interfaces.
