7.3 Fieldbuses
7.3.1 HART
You can communicate using the HART protocol via current output 1.
‣ Connect the HART modem or handheld to current output 1 (communication load 230 - 500
Ohm).
‣ Establish the connection via your HART device.
‣ Operate Liquistation via the HART device. To do so, follow the instructions in the manual.
All the information on HART communication is provided on the CD (--> BA00486C).
7.3.2 PROFIBUS-DP
With the fieldbus module 485 and the appropriate device version, you can communicate via
PROFIBUS DP.
Connect the PROFIBUS data cable to the terminals of the fieldbus module as described (-->
BA00443C "Commissioning").
7.3.3 Modbus
With the fieldbus module 485 and the appropriate device version, you can communicate via
Modbus RS485 or Modbus TCP.
Connect the Modbus data cable to the terminals of the fieldbus module (RS 485) or to the RJ45
(TCP) port as described (--> BA00443C "Commissioning").
