Field connections
The FLOWSIC600-XT is connected to the serial COM Port 1 of the module used via the
corresponding RS485 interface. Terminal 81/82 is used for this purpose on the
FLOWSIC600. For connection with a 2-wire RS-485 connection, it is sufficient to use the
Tx+ and Tx terminals. Alternatively, an Ethernet connection can be used to connect the
FLOWSIC600-XT and flow computer.
The pressure transmitter is connected to the Analog 1/HART 1 port, while the temperature
transmitter is connected to the Analog 2/HART 2 port of the Flow-X flow computer module
used.

WARNING:
Before connecting the analog signals to the flow computer, make sure the analog input
values (voltage/current) and ranges are configured correctly. Incorrect configuration
can cause damage to the inputs.

Both transmitters can receive their 24 V supply voltage via internal supply from the
Flow-X flow computer and can be connected accordingly. This may require additional
cables.
An external supply is also possible, the correct connection is described in
