Hello everybody! I need some help about RSE. I have developed the diagnostic system on the base of RSE. It seems to work fine, but there is a problem. There are two arrays in automatically generated data block "Diagnostic status DB" with names "MASTERSTATUS_FAILED" and "MASTERSTATUS_FAULTY".
Accordingly to the data block description in STEP7 Manual these arrays consists of bits indicating DP Master System with faulty or failed station.

During experimental tests some bugs were found. If problem with SM331 appears, RSE works fine and coresponding bit of array "MASTERSTATUS_FAULTY" is set to "1". When the problem is eleminated corresponding bit remains set to "1" until new problem appears and disappears fast. On the other hand if the duration of problem is more than several seconds then bit remains set to "1".

Other fields of data block "Diagnostic status DB" work fine. Notes from STEP7 Manual with field i am talking about is in attachment.

P.S. Sorry for my English.  English is not my native language.
