System integration
The FCT010 transmitter functions as a Modbus RTU slave with standard Modbus commands
implemented. Setup parameters, process values, diagnostics, and status information are
mapped as Modbus registers.
The device can be connected point-to-point or in a multidrop network in non-hazardous or
hazardous areas. It can be connected to different hosts for example a PLC system or a PC used as
service tool or configuration tool.
Note
Multidrop installations in hazardous areas
Multidrop installations in hazardous areas require explosionproof conduit seals for each device
in division 1 wiring.
For zone classified locations use of Ex-d cable gland can be used if permitted by national
installation regulation.
The MASS2100 and FC300 7ME4817-... are preconfigured for integration with the SITRANS
FCT070.

Modbus RTU technology FCT010
Modbus RTU is an open serial protocol based on master/slave architecture. The protocol
interconnects field equipment such as sensors, actuators, and controllers and is widely used in
both process and manufacturing automation. The fieldbus environment is the base level group
of digital networks in the hierarchy of plant networks.
