Configuration

3.5

Limit Conditions for Calibration:

For every writing operation in the transducer blocks there is a code indication for the operation
associated with the writing method. These codes appear in parameter XD_ERROR every time a
calibration is performed. Code 16, for example, indicates a successfully performed operation.

Lower:

0.0mA < NEW_ LOWER < 9.0mA
Otherwise, XD_ERROR = 22

Upper:

15.0 mA < NEW_UPPER < 22.0mA
Otherwise, XD_ERROR = 22.

NOTE

Codes for XD_ERROR:

… 16: Default Value Set
… 22: Out of range
… 26: Invalid Calibration request
… 27: Excessive Correction

Display Transducer Block

The local adjustment tree is completely configured by

SYSCON

. 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 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 shows significantly the resources on this
transducer display. All Series 302 field devices from SMAR have 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 blocks and transducers defined according Foundation Fieldbus



have a description of

their features written on binary files, by the Device Description Language. This feature permits that
third parties configurator 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.

In order to enable the local adjustment using the magnetic tool, it is necessary to previously prepare
the parameters related with this operation via

SYSCON

(System Configurator). The Figure 3.8 -

Parameters for Local Adjustment Configuration and the Figure 3.11 - Step 1 - IF302 show all
parameters and their respective values, which shall be configured in accordance with the necessity
of being locally adjusted by means of the magnetic tool. All values shown on the display are default
values.

There are seven groups of parameters, which may be pre-configured by the user in order to allow 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 write an invalid Tag in the parameter,
Block_Tag_Param_X. Doing this, the device will not take the parameter related (indexed) to the Tag
as a valid parameter.

Definition of Parameters and Values

Block_Tag_Param

This is tag of the block to which the parameter belongs. Use up to a maximum of 32 characters.

Index_Relative

This is the index related to the parameter to be actuated or viewed (0, 1, 2…). Refer to the Function
Blocks Manual to know the desired indexes, or visualize them on the SYSCON by opening the
desired block.
