Server Side Limitations  

The  DNP  3.0  Server  can  only  parse  a  single  poll  per  message.   This means  that  a  single  message 
cannot contain more than one read request - You cannot read two different objects types/variations in 
a single read request.  The same limitation applies to write commands sent the Server.
