B.6 Example Of A Profibus Trace - Siemens SIMATIC FC 45 Function Manual

B.6 Example of a PROFIBUS Trace
B.6
The following trace shows all telegrams which were sent on the PROFIBUS interface during
an ASM start-up or a MOBY read command. The trace illustrates the information in Sections
"Cyclic control word between master and MOBY-ASM" to "PROFIBUS implementation". It
can also be used for orientation or for trouble-shooting of customer-specific MOBY-ASM
implementations.
Note
Using FC 45 on PROFINET
If the FC 45 is used on PROFINET, the PROFINET trace is similar to the PROFIBUS trace.
The data contents are identical. The header data of the telegrams are different.

Programming the MOBY-ASM on PROFIBUS

B.6 Example of a PROFIBUS Trace

Start-up of ASM
FC sets the start-up bit.
ASM sets the command counter to one.
FC resets the start-up bit.
ASM also resets the start-up bit.
RESET telegrams to 4th channel
PROFIBUS confirmation of the RESET
Command counter for 4th channel is incremented to
2.
Acknowledgment counter for 4th channel is
incremented to one.
Optional: Presence is set.
Request of FC for a non-cyclic telegram
Return acknowledgment telegram of the RESET to
the FC
