DNP Float Output Data
This data type stores Float values sent from the DNP master unit to the module
and PLC. The size of this data area is determined from the configuration
parameter Float Outputs. These data are transferred from the module to the PLC
using the write operation. Therefore, these data are read-only for the PLC, as the
PLC cannot directly alter these values in the module. It is the responsibility of the
DNP master unit to maintain this data. For example, if the DNP master sends a
value of 3405.000 to the module for a specific point, the value will be stored in
the module until changed by the master. A data flow diagram for the float output
data is shown in the following figure.
