5.2 Design of the Process Data for PROFIBUS-DP
Depending on how the coupler is parameterized, the status bytes (S), control
bytes (C) and data bytes (D0...Dn) of the byte or word orientated modules are
transmitted via PROFIBUS in Motorola or Intel format.
Attention
For the meaning of input and output bits or bytes of the individual I/O
module please refer to the corresponding I/O module description.
