In its current version, this Driver only allows PLC Tags and Block Tags.

The type or name of a message must be informed in the Item parameter. The Device, N1, N2, N3, and N4 parameters are not used.

As soon as this Driver receives a message of the same type, the values are received according to the order they were declared in the file HL7BlockDefs.map.

As an example, if the file HL7BlockDefs.map declares a message ADT_A01 with 3 (three) information items, users must create a Block Tag with 3 (three) Elements to receive those information items, defining the Item parameter with the address ADT_A01.
