So I took my BT-200, an Osciloscope, and a Diagnostic Repeater and I went to the plant.
The osciloscope shapes are ok, pretty squares.
BT200 and diagnostic repeater shows that net is in order (the whole net is inside a cabinet).

QUESTIONS :
My questions are about the Online diagnosis that I took from the CP342 NCM window.

Figure NCM S7_1:
How Should I interpretate the statistics that appear in the LAYER2 diagnosis?
What is SP0 overflow?
What are the HSA LAS items from the Bus Error Diagnosis?
Is there any manual that explain this better that the help file?


Figure NCM S7_3:
How should I interpretate the Station's ICONS?, Some are Black, some Gray and some are grey and have a "R". ALL slaves are PASIVE.
If they are black, and if I disconnect the slave, appears a red cross, showing that there is a failure, and that is OK., but that, does not happend with the grey ones and the ones with the "R".
the help file, is very bad, there nothing there. any idea? is there a manual were I can lern this?

Hope someone can help me on this.

This specifies the highest PROFIBUS address of an active −> station on PROFIBUS. Addresses higher than the highest station address (HSA) are possible for passive stations.
If a station with a higher address as HSAwas detected on the bus, you would see it in NCM (HSA exceeded <> 0)

LAS = List of active stations
Each active station (DP master or system accepting and forwardingthe token) has to keep a list of all other active stations on the bus (to be able to forward the token to the correct NS = next active station). If the CP had a problme by creating the list, you would see it in NCM (LAS errors <> 0)
