System diagnosis. The master's slave parameter record contains<br />
diagnostic data for this slave. Possible causes:<br />
a: Master has found a local failure<br />
b: Slave has sent diagnostic data<br />
c: Slave did not explicitly cleared extended diagnostic data<br />
Data transfer. Master an DP slave exchanged a valid data frame within<br />
the set Date <strong>Control</strong> Time.<br />
Telegram buffer overflow. Slave responded by sending a longer frame<br />
than expected. Not enough buffer memory for telegram data. Possible<br />
cause: The entry for Max_Diag_Data_Len in this SP slave's GSD file is<br />
not identical with the length of the frame that was actually sent.<br />
