How to Configure the Transducer Block
The transducer block has an algorithm, a set of contained parameters and a channel connecting it to
a function block.
The algorithm describes the behavior of the transducer as a data transfer function between the I/O
hardware and other function block. The set of contained parameters, it means, you are not able to
link them to other blocks and publish the link via communication, defines the user interface to the
transducer block. They can be divided into Standard and Manufacturer Specific.
The standard parameters will be present for such class of device, as pressure, temperature,
actuator, etc., whatever is the manufacturer. Oppositely, the manufacturer’s specific ones are
defined only for its manufacturer. As common manufacturer specific parameters, we have calibration
settings, material information, linearisation curve, etc.
When you perform a standard routine as a calibration, you are conducted step by step by a method.
The method is generally defined as guideline to help the user to make common tasks. The
configuration tool identifies each method associated to the parameters and enables the interface to
it.
The Simatic PDM (Process Device Manager) configuration software from Siemens, for example, can
configure many parameters of the input transducer block.
