(6) Set the operation mode to AUTO.
NOTE
To confirm the setting of flow calculation, use
Simulation Function. See ‘6.3.6 Simulation
Function.’
6.4.4 Flow Unit/Decimal Point Digit
The flow unit is indicated in the
FLOW_VALUE_UNIT parameter and the number of
digits past the flow decimal point is indicated in the
FLOW_VALUE_DECIMAL parameter. As the content
of these parameters is interlocked with sub parameters
Unit and Decimal of XD_SCALE in the AI function
block where the flow signal is selected,
FLOW_VALUE_UNIT and
FLOW_VALUE_DECIMAL also are automatically
changed when XD_SCALE.Unit and
XD_SCALE.Decimal are changed.
6.4.5 Flow Type Selection
Mass flow, volume flow and standard volume flow are
automatically selected according to the flow unit. The
currently selected flow type can be referenced at the
FLOW_VALUE_TYPE parameter.
6.4.6 BLOCK_ERR
The BLOCK_ERR parameter indicates the cause of
errors that occur in the block. On the FLOW transducer
block, check the following error causes, and set the bit
corresponding to the cause.

Not supported O/S is set for ModeBLK.Target.
*1: The mode other than O/S is set for ModeBLK.Target.
*2: The flow value is zero or less. This is supported only in the Auto
Compensation mode.
*3: The sum value of the Auto Compensation flow setting does not agree
with the value when it was written by the setup tool.
6.4.7 XD_ERROR
The XD_ERROR parameter indicates the most impor-
tant error code among the errors that are currently
occurring on the FLOW transducer block. The follow-
ing table summarizes the content of supported
XD_ERRORs and error codes.
When two or more error codes are being generated
simultaneously, error codes are displayed with prefer-
ence given to the largest error code.

FLOW TB is in the O/S
mode.
Other than O/S is set even
though it is a Multi
Sensing type.
The flow setting sum
value does not agree with
the value when it was
written by the setup tool.
The flow value is smaller
than zero.
6.5 LCD Transducer Block
6.5.1 Outline of the Functions
The LCD transducer block controls alarms and
measured values that are displayed on the integral
indicator. It displays not only OUT signals from the AI
blocks, but also I/O signals of the Installed blocks on
the integral indicator.
6.5.2 Block Mode
The Block modes permitted for the LCD transducer
block are Automatic (Auto) and Out of Service (O/S).
Settings can be changed in the AUTO mode for this
block, except the Block tag parameter.
6.5.3 Display Contents of the integral
indicator
The components of the integral indicator are the bar
graph, the title field, the center field for numerical
values, the lower text field, and auxiliary characters.
The contents and meanings of these components are as
follows:
