FI303 - Operation and Maintenance Instruction Manual
3.18
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 user interface 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.
Select/Set Parameter Type/Index
This is the index related to the parameter to be actuated or viewed (0, 1, 2…). For each block there
are some pre-defined indexes. Refer to the Function Blocks Manual to know the desired indexes
and then just enter the desired index.
Set Mnemonic
This is the mnemonic for the parameter identification (it accepts a maximum of 16 characters in the
alphanumeric field of the display). Choose the mnemonic, preferably with no more than 5 characters
because, this way, it will not be necessary to rotate it on the display.
Set Decimal Step
It is the increment and decrement in decimal units when the parameter is Float or Float Status
value, or integer, when the parameter is in whole units.
Set Decimal Point Place.
This is the number of digits after the decimal point (0 to 3 decimal digits).
Set Access Permission
The access allows the user to read, in the case of the “Monitoring” option, and to write when "action"
option is selected, then the display will show the increment and decrement arrows.
Set Alpha Numerical
These parameters include two options: value and mnemonic. In option value, it is possible to display
data both in the alphanumeric and in the numeric fields; this way, in the case of a data higher than
10000, it will be shown in the alphanumeric field.
