Data Sheet
6.0 Appendix (A) – Manchester Encoding
All Fieldbus devices transmit the data onto the media as a Manchester-encoded baseband signal. With Manchester encoding, zeros
and ones are represented by transitions that occur in the middle of the bit period (see below). For Foundation Fieldbus H1 and Profibus
PA, the nominal bit time is 32
μ
sec, with the transition occurring at 16
μ
sec. The Manchester encoding rules have been extended to
include two additional symbols, non-data plus (N+) and non-data minus (N-). The symbol encoding rules are shown below.
