A reference designator unambiguously identifies a component in an electrical schematic or on a printed circuit board and usually consists of one or two letters followed by a number, for example R10. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, for example, R12A, R12B. The Institute of Electrical and Electronics Engineers (IEEE) has a standard with a list of class designation letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C represents capacitors, and K represents relays.

Note
The hyphen ( – ) character will always try to call an expansion to the references. In this case, the only option is to change it to an underscore ( _ ) however, this also involves changing the references in the ECAD section of FactoryLogix. FactoryLogix only interprets data as a range if the data before the hyphen matches the data after the hyphen. For example, U1-C2, U2-C2 is interpreted as two references.
