For SCADAPack 32 and SCADAPack 32P controllers counter input events are processed by the
DNP driver at a rate of 100 events every 100 ms. If more than 100 counter 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 counter input events per second.
For SCADASense Series of controllers, SCADAPack 100, SCADAPack LP, SCADAPack and
Micro16 controllers counter input events are processed by the DNP driver at a rate of 20 events
every 100 ms. If more than 20 counter 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 counter
input events per second.
The Word Order selection specifies the word order of the 32-bit value. The selections are:
 TelePACE Least Significant Word in first register.
 ISaGRAF Most 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.
