Parameter Group Number represents the identifier of a J1939 message.
Every J1939 message has a unique PGN assigned to it by the SAE committee when the message is defined.
A PGN is 18-bits wide and is made up of the following fields:
Extended Data Page, Data Page, PDU Format
Depending on the value of the PDU Format field, a message is either destination-specific, meaning it is for a specific node.
