events occur and the rate at which the events are reported to the master station. The valid values for
this parameter are 0 - 65535. Default value is 16.
For SCADAPack 32 and SCADAPack 32P controllers analog input events are processed by the DNP
driver at a rate of 100 events every 100 ms. If more than 100 analog input events need to be
processed they are processed sequentially in blocks of 100 until all events are processed. This allows
the processing of 1000 analog input events per second.
For SCADASense Series of controllers, SCADAPack 100, SCADAPack LP, SCADAPack and
Micro16 controllers analog input events are processed by the DNP driver at a rate of 20 events every
100 ms. If more than 20 analog input events need to be processed they are processed sequentially in
blocks of 20 until all events are processed. This allows the processing of 200 analog input events per
second.
The Word Order selection specifies the word order of the 32-bit value. The selections are:
 TelePACE / ISaGRAF (MSW First) Most Significant Word in first register.
 Reverse (LSW First) Least Significant Word in first register.
The Allow Duplicate Modbus Addresses checkbox determines if the Modbus I/O database
addresses assigned to the DNP data points must be unique. Check this box if you want to allow more
than one point to use the same Modbus address.
