Mapping of process data in the process image of fieldbus systems
The representation of the process data of some I/O modules or their variants in the
process image depends on the fieldbus coupler/controller used. Please take this
information from the section "Fieldbus Specific Design of the Process Data"
included in the description concerning the process image of the corresponding
fieldbus coupler/controller.

The 750-597 I/O module provides 1 status byte (8 bit) and 1 data word (16 bit) per
channel.
The digitized process value is output in a data word via the process image of the
fieldbus coupler/controller as output byte "0" (low) and output byte "1" (high).
The process value is displayed at the following resolution:
• Signal type „0-10 V": 15 bit (bit B0 ... B14)
• Signal type "+/- 10 V": 16 bit (bit B0 ... B15)
