Section 3
3.1
CONFIGURATION
This section describes the characteristics of the blocks in the
LD303
. They follow the Profibus PA
specifications, but in terms of transducer blocks, the input transducer block and display, they have
some special features on top of this.
The 303 Smar family is integrated in Profibus View from Smar and Simatic PDM from Siemens. It is
possible to integrate any 303 Smar devices into any configuration tool for Profibus PA devices. It is
necessary to provide a Device Description or Drive according to the configuration tool. In this
manual is taken several examples using Profibus View or Simatic PDM.
In order to assure correct values in the offline configuration, first run “Download to PG/PC” option to
assure valid values. After, run the Menu Device option to configure the required parameters using
the related menus.
NOTE
In offline configuration, it is not advisable to use the “Download to Device” option. This function can
misconfigure the equipment.
Transducer Block
Transducer block insulates function block from the specific I/O hardware, such as sensors,
actuators. Transducer block controls access to I/O through manufacturer specific implementation.
This permits the transducer block to execute as frequently as necessary to obtain good data from
sensors without burdening the function blocks that use the data. It also insulates the function block
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 Function block is called channel. These blocks can
exchange data from its interface.
Normally, transducer blocks perform functions, such as linearization, characterization, temperature
compensation, control and exchange data to hardware.
