7.3 Connection variants
The sensor is a 2-wire device with a passive 4...20 mA current output and HART ® interface.
• Multidrop mode is supported Multidrop mode is supported Multidrop mode is supported Multidrop mode is supported
In a multidrop communication system, more than 2 devices are connected to a common
transmission cable.
• Burst mode is not supported Burst mode is not supported Burst mode is not supported Burst mode is not supported
In the burst mode a slave device transfers cyclic pre-defined response telegrams, to get a
higher rate of data transfer.
There are two ways of using the HART ® communication:
• as Point-to-Point connection and
• as Multidrop connection, with 2-wire connection.
INFORMATION!
