Connection of the flowmeter SITRANS FC410 to a CPU S7-1200 via MODBUS RTU

  • Entry
  • Associated product(s)
The SITRANS FC410 flowmeter with digital MODBUS RTU interface is connected to a controller. The controller converts the digital input signals to an analog 4-20 mA output signal.

The application example describes the communication of a MODBUS master with a slave (in this case SITRANS FC410) as a gateway. Independent of the master/slave communication, measured values are read in parallel and made available as 4-20 mA analog signal.
The Siemens automation system S7-1200 is used as hardware. The automation system is equipped with two communication modules and has one analog output card.
