_daveConnection struct _daveConnection: A structure representing the physical connection to a single PLC. daveConnection stores all properties that are unique to a single PLC: - The MPI address of this PLC. - The rack the PLC is in. - The slot the PLC is in.
_daveInterface struct _daveInterface: A structure representing the physical connection to a PLC or a network of PLCs (e.g. like MPI). daveInterface stores all those properties that are common to a network of PLCs: - The local address used by your computer. - The speed used in this network. - The protocol type used in this network. - A name which is used when printing out debug messages. * The structure daveInterface is created and initialized by daveNewInterface: *
