Configuring control strategies to obtain correct
process values
1. The parameter "Tag Name" is read correctly by DeltaV. No additional configuration is required with
regard to the value; it can be used directly from its Dataset.
2. For the first 11 parameters (Avg. Distance, Min Distance, Max Distance, Volume, 4-20mA, SNR,
Temperature °C, Temperature °F, Avg. Level, Bulk Density, and Mass), the byte order must be
swapped and converted from binary to floating point. A control strategy with the configuration
shown below is used.
3. In the control strategy, set up the following parameters in the function blocks and variables (see

1-7):
a. AI1: For Device Tag use Browse... to add the newly defined Dataset (Dataset1). For Parameter,
assign the first Modbus register.
b. AI2: For Device Tag use Browse... to add the newly defined Dataset (Dataset1). For
Parameter, assign the second Modbus register.
c. PV: Parameter type should be defined as Floating point with status.
d. SING: Parameter type should be defined as Floating point.
e. MANTISSA: Parameter type should be defined as Floating point.
f. EXPONENT: Parameter type should be defined as Floating point.
g. CALC1: Enter the expression in
