Actually this is by design.
1) In a MODBUS PDU data is addressed from 0 to 65535 (0 origin)
2) In the MODBUS data Model each element within a data block is numbered from 1
to n
(1 origin)
3) .NET collections are of 0 origin
In order to be true to the Modbus data model I created the
ModbusDataCollection, a 1
origin collection.
