8 Bus systems
8.1 Modbus
The MODBUS data transfer of the HYGROPHIL
®
F 5673 uses the RTU
(Remote Terminal Unit) mode. It is always a MODBUS slave and is physical-
ly transmitted through a RS485 connection. The RS485 line has to be con-
nected on clamps 414(-) and 415(+).
Alternatively the MODBUS can be operated via RS232 interface. You can
select the interface in the “Modbus/Profibus” menu (see section 5.6.7).
