B.8

Example of a PROFIBUS Trace

The following trace shows all telegrams which were sent on the PROFIBUS
interface during an ASM startup or a MOBY read command. The trace illustrates
appendices B.1 to B.7. It can also be used for orientation or for trouble-shooting of
customer-specific MOBY-ASM implementations.
