 Have admissible bus parameters been set only? If you are in doubt

set them to default values.

 Is it guaranteed that the PROFIBUS master has consistent access

to the 16 byte sensor data structure?

Note for Siemens PLC with programming language STEP7:
The following commands have to be used for consistent access:

– SFC15 (for writing)

– SFC14 (for reading)

 After commissioning:

Do all devices signal error-free behavior?
(DIQ/S 182-PR: status "Online" in the measured value and status
display).
