7.2.1 How the Module Connects to a Field Device
The HART output module behaves as a HART master in which case the field device is
considered the slave. In other words, the master must initiate the communication with the
field device and the device simply replies with an appropriate response. Any given
channel may have a master, a secondary master (hand held configuration tool), and a
slave connected simultaneously. Please see Figure below.
