ControlNet Description  

The ControlNet driver allows the FieldServer to transfer data to and from devices using 
ControlNet protocol.  The SST 5136-CN-ISA Communications Adapter card is included with the 
FieldServer.  The FieldServer can communicate using un-scheduled transfers with PCCC 
messages embedded in the ControlNet messages. 
 
When the FieldServer originates PCCC messages to communicate with PLC5 controllers, it 
uses connected messages.  This provides fast reliable communication to the other node.  When 
another device originates PCCC messaging, the FieldServer will emulate a PLC5 controller 
supporting connected or unconnected messages to files N7 through to N32..
