2.1.2.7 Process Image

Using the I/O module 750-404, a 5 byte input and output process image can be
transferred to the fieldbus coupler / controller via one logical channel.
The transfer of the setting counter value in binary format is made via 4 output
bytes (D0 ... D3) and the transfer of the counter reading in binary format is
made via 4 input bytes (D0 ... D3). The control byte C0 serves for setting the
counter and the outputs. The status byte S0 shows the status of the counter and
the inputs and outputs.
Attention
The representation of the process data of some I/O modules or their variations
in the process image depends on the fieldbus coupler/-controller used. Please
take this information as well as the particular design of the respective
control/status bytes from the section "Fieldbus Specific Design of the Process
Data" included in the description concerning the process image of the
corresponding coupler/controller.
