Transducer Display – Configuration
Using the Syscon or any other configuration tool is possible to configure the Display Transducer
block. As the name described it is a transducer due the interfacing of its block with the LCD
hardware.
The Transducer Display is treated as a normal block by any configuration tool. It means, this block
has some parameters and those ones can be configured according to customer's needs.
The customer can choose up to seven parameters to be shown at LCD display; they can be
parameters just for monitoring purpose or for acting locally in the field devices by using a magnetic
tool. The first two parameters will be toggle in the display.
Display Transducer Block
The local adjustment is completely configured by SYSCON 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 SYSCON, 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 with 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 302 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 functions blocks and transducers defined according Profibus PA have a description of their
features written, 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 Transducers of Series 302 have
been defined rigorously according the Foundation Fieldbus specifications in order to be
interoperable to other parties.
This parameter is
used to save or
restore the
default, factory or
user
configuration
stored at the
sensor module.
