Integrating the FC410 with Modbus system
This chapter provides information on how to integrate the flowmeter in a point-to-point or
multidrop Modbus RTU network in non-hazardous or hazardous locations. Many details of
network design are beyond the scope of these operating instructions. The points below
provide an overview of the major design criteria. For further details contact Siemens.
If the device is integrated in a hazardous location, two flameproof conduit seals per device
must be installed; one at the device in the hazardous location and one in the non-hazardous
location, see System configurations (Page 43).
