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 in the section related to "Programming Using Local
Adjustment". It is significantly the resources on this transducer display, also all the 303 series 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 on binary files by the Device Description Language.
This feature permits that third party configuration tools enabled by Device Description Service
technology can interpret these features and make them accessible to configure. The function blocks
and 303 series transducers have been defined rigorously according to 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 Syscon.
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.
