The data sent and received is stored in 2 output bytes(D0, D1) and 5 input bytes (D0 … D4). The output bytes D2 ... D4 arereserved and without function. One control byte (C0) and one status byte (S0)are used to control the data flow.AttentionThe representation of the process data of some I/O modules or their variationsin the process image depends on the fieldbus coupler/-controller used. Pleasetake this information as well as the particular design of the respectivecontrol/status bytes from the section "Fieldbus Specific Design of the ProcessData" included in the description concerning the process image of thecorresponding coupler/controller.
