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 "I/O Modules" included in the description
concerning the process image of the corresponding coupler/controller.
The I/O Module 750-439 provides the fieldbus coupler/controller 2 bytes in the
input and output process image.
The signal status of inputs DI 1 ... DI 8 is transmitted to the fieldbus
coupler/controller via input data byte D0, the error status via input data byte D1.
Diagnostic deactivation is transferred to the I/O module via output data byte D1.
Output data byte D0 determines whether a make contact or break contact is
connected.
