Output Data
The output data is transmitted from the fieldbus coupler to the I/O module. The
process image of the I/O module can contain process data with or without
diagnostic confirmation. If you have parameterized a synchronous diagnostic
confirmation, the process image has a size of 5 bytes. Otherwise, only 4-byte
process data is contained in the process image.
The process data and the diagnostic confirmation are structured as follows:
