CONFIGURATION
One of the many advantages of Fieldbus is that device configuration is almost indepen-dent of the
configurator. The
FI303 may be configured by a third party terminal or operator console.
The
FI303 contains three output transducer blocks, one physical block, one display transducer block
, three analog output function blocks.
Function Blocks are not covered in this manual. For explanation and details of function blocks, see
the “Function Blocks Instruction Manual”.
The transducer block isolates the function block of the specific I/O hardware, like sensors and
actuators, for example. Transducer block controls access to I/O through manufacturer specific
implementation. This permits the transducer block to execute the algorithm, as frequently as
necessary to obtain good data from sensors without burdening the function blocks that use the data.
It also insulates the function blocks from the manufacturer specific characteristics of certain
hardware.
By accessing the hardware, the transducer block can get data from I/O or passing control data to it.
The connection between Transducer block and Input/Output Function blocks is called channel.
Normally, transducer blocks perform functions, such as linearization, characterization, temperature
compensation, control and exchange data to/from hardware.
In order to assure correct values in the offline configuration, when using download function of
Simatic PDM, please make sure you have done the upload firstly.
Offline Configuration
1. First run “Download to PG/PC” option to assure valid values.
2. Run after the Menu Device option to configure the required parameters using the related menus.
NOTE
It is not advisable to use the “Download to Device” option. This function can misconfigure the equipment.
How to Configure a 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, 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 manufacturers specific ones are
defined only by its manufacturer. As common manufacturer specific parameters, we have calibration
settings, material information, linearization 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 guide line to help the user to make common tasks. The
Configuration Tool identifies each method associated to the parameters and enables the interface
to it., linearization curve, etc.

Terminal Number
The terminal number, which references a channel value, which is sent via internal, manufacturer-
specific from the specified transducer, output to function block.
