DNP Analog Output Data
This data type stores analog values sent from the DNP master unit to the module
and PLC with a data range of 0 to 65535 or -32768 to 32767. The size of this
data area is determined from the configuration parameter Analog 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 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 analog output data is shown in the
following figure.
