Block model of PROFIBUS PA/DP
In the PROFIBUS configuration, all the device parameters are categorized according to their
functional properties and tasks and are generally assigned to three different blocks. A block
may be regarded as a container in which parameters and the associated functionalities are
contained.
A PROFIBUS device has the following block types (see
•
A Physical Block (device block)
The Physical Block contains all device-specific features of the unit.
•
One or more Transducer Blocks
The Transducer Block contains all the measuring and device-specific parameters of the
device. The measuring principles (e.g. conductivity, temperature) are depicted in the
Transducer Blocks in accordance with the PROFIBUS Profile 3.0 Specification.
•
One or more function blocks
A function block contains the automation functions of the device. The transmitter contains
Analog Input blocks by means of which the measured values can be scaled and examined
for limit value overshoot.
A number of automation-related tasks can be implemented with these blocks. In addition to
these blocks, a transmitter can have any number of additional blocks, for example several
Analog Input function blocks if the transmitter can process more than one process variable.
