Specifications
Overview
The field-mount temperature transmitter can be configured via FDT / DTM in DAT200 (Asset Vision Basic) or any standard FTD tool via EDD or local HMI (optional). The Field Information Manager (FIM) is also supported via FDI technology. For PROFIBUS the configuration is possible via GST-file, EDD or DTM and for FOUNDATION Fieldbus via EDD.
