Master Poll
The Master Poll property page is selected for editing by clicking Master Poll in the tree control
section of the DNP Settings window. This selection is only visible if the controller type is a
SCADAPack 330/334, SCADAPack 350, SCADAPack 32 or SCADAPack 32P. These controllers
support DNP Master. When selected the Master Poll property page is active and button Copy is
renamed to Edit.
The Master Poll displays slave devices to be polled by this master station as a row, with column
headings, in the table. The table may have up to 1000 entries. A vertical scroll bar is used if the list
exceeds the window size.
Note: All slave devices in the Master Poll table need to be added to the Routing table.
The Station column displays the address of the DNP slave device to be polled. Each entry in the
table should have unique DNP Station Address.
The Class 0 Rate column displays the rate of polling for Class 0 data, as a multiple of the base poll
interval.
The Class 1 Rate column displays the rate of polling for Class 1 data, as a multiple of the base poll
interval.
The Class 2 Rate column displays the rate of polling for Class 2 data, as a multiple of the base poll
