Display Transducer Block
The local adjustment is completely configured by
Simatic PDM or any configuration tool . It
means, the user can select the best options to fit his application. From factory, it is configured with
the options to set the Upper and Lower trim, for monitoring the input transducer output and check
the Tag. Normally, the transmitter is much better configured by
Simatic PDM or configuration tool ,
but the local functionality of the LCD permits an easy and fast action on certain parameters, since it
does not rely on communication and network wiring connections. Among the possibilities by Local
Adjustment, the following options can be emphasized: Mode block, Outputs monitoring, Tag
visualization and Tuning Parameters setting.
The interface between the user is described very detailed on the "General Installation, Operation
and Maintenance Procedures Manual". Please take a detailed look at this manual in the chapter
related to "Programming Using Local Adjustment". It is significantly the resources on this transducer
display, also all the
Series 303 field devices from SMAR has the same methodology to handle with
it. So, since the user has learned once, he is capable to handle all kind of field devices from SMAR.
All function block and transducers defined according Profibus PA have a description of their features
written by the Device Description Language.
This feature permits that third parties configuration tools enabled by Device Description Service
technology can interpret these features and make them accessible to configure. The Function
Blocks and Transducers of Series 303 have been defined rigorously according the Profibus PA
specifications in order to be interoperable to other parties.
In order to able the local adjustment using the magnetic tool, it is necessary to previously prepare
the parameters related with this operation via System Configuration.
There are six groups of parameters, which may be pre-configured by the user in order to able, a
possible configuration by means of the local adjustment. As an example, let’s suppose that you
don’t want to show some parameters; in this case, simply select "None" in the parameter, "Select
Block Type". Doing this, the device will not take the parameters related (indexed) to its Block as a
valid parameter.
Definition of Parameters and Values
Select Block Type
This is the type of the block where the parameter is located. The user can choose: Transducer
Block, Analog Input Block, Totalizer Block , Physical Block or None.
