Process Image

2.1.2.7 Process Image
Using the I/O module 750-511 or 750-511/000-002, a 6 byte input and output
process image can be transferred to the fieldbus coupler / controller via two
logical channels. The setting of the On/Off times occur in the four output
bytes (D0, D1) or (D2, D3). The four input bytes (D0, D1, D2, D3) and the
status bytes (S0, S1) are not used for the On/Off time settings.
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.

The programming of the On/Off times occur with the resolution of 10 bits.
The five LSB of the 16 bit are not defined. In the table these bits are
represented with a 'X'. The indication of the hexadecimal and the decimal
numerical values in the table considers the condition ' 0 ' for the first five low
order bits in each case. If these five bits accept the condition ' 1 ', the decimal
numerical value is higher around 31, than indicated in the table.
The MSB will hold the sign and is preset to the null state.
