Both the HART input and Output module behave 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 3.
