The HART analog modules are used in the distributed I/Os attached to
PROFIBUS DP (see Figure 4-1).
You can connect one field device to each of the two channels on a HART
analog module: the module acts as HART master, the field devices as HART
slaves.
Different software applications can transmit or receive data via a HART
analog module. These applications can be compared to clients, for which the
HART analog module acts as a server.
