PROFIBUS PA/DP block model

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 functions
are contained (see ).
A PROFIBUS device has the following block types:
• A physical block (device block)
The physical block contains all the device-specific features of the device.
• 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 (function block)
A function block contains the device' s automation functions. The transmitter contains
Analog Input Blocks which can be used to scale the measured values and to check for
limit value overshoot.
A number of automation tasks can be implemented with these blocks. In addition to these
blocks, a transmitter can also contain any number of other blocks. These can include, for
example, several analog input function blocks if more than one process variable is provided
by the transmitter.

7.1.1 Physical block (device block)
A physical block contains all the data that uniquely identify and characterize the
transmitter. It is an electronic version of a nameplate on the transmitter. Physical blocks
parameters are e.g. device type, device name, manufacturer identification, serial number.
